Rigmaster has a new pricing promotion.
Wednesday, October 22nd, 2008TORONTO — RigMaster has announced its “Roll Back the Hands of Time” promotion that will make it more attractive to purchase the RigMaster APU this fall.
RigMaster has rolled back the price of all T2 model units to pre-2005 pricing levels, offering customers a net savings of up to 10 percent, if purchased and installed between now and December 31st, 2008.
The RigMaster T2 APU burns just 2/10 gallon per hour and can save enough fuel to pay for itself in a year. It provides the operator with heating, air conditioning, 6000 Watts of electrical power for in-cab appliances and a 60 Amp DC alternator that charges the truck’s batteries. Available with either a Perkins or a Caterpillar engine, the T2 model is EPA compliant and can be operated in California when installed on 2006 or older model trucks.
“This is a great opportunity for everyone who has wanted to purchase an APU, but couldn’t afford it,” says Amy Egerter, RigMaster’s Marketing and Communication manager. “In a time when the rest of the industry is raising prices, we have lowered ours to help our customers be more profitable by reducing their idling and fuel costs.”
Land Line magazine reports on Idlebuster financial woes and temporary shutdown.
Wednesday, October 22nd, 2008CEO says APU-maker IdleBuster will return after 90 days
Cash flow problems and the recent credit crunch have shaken firms from Wall Street to Main Street, and also have prompted one APU-maker to temporarily shutter its manufacturing facilities.
IdleBuster will take a 90-day hiatus to regroup before reopening early next year, Wade Gordon, the company’s industry liaison, told Land Line Magazine. IdleBuster is a division of Odessa, FL-based OX Brands LLC.
“We’re not shutting down per se,” Gordon said. “We’ve invested over $15 million into APUs trying to build the best in the market. With the economy like it is, it’s not just hurting us, it’s hurting everyone.”
Service contracts that drivers have for oil changes through another party are still valid, Gordon said. Maintenance or repair bills covered by the company’s warranty will be repaid, Gordon said.
“If a person has a warranty issue and they repair it themselves, write down engine hours, date and where you had it repaired, submit the invoice to us,” Gordon said. “It may take 90 days – but you will be reimbursed.”
Some vendors owe IdleBuster money, and the credit crisis has limited available capital, Gordon said.
About 450 to 500 truck drivers are using APUs built by IdleBuster, Gordon estimated.
Gordon, an OOIDA member and longtime driver himself, said his company’s optimism about the APU market led to the temporary closing rather than a permanent one.
“It’s gonna be a tough time – but IdleBuster believes that they service the most vital industry in the country, the truck driver,” Gordon said. “I will not let the drivers be left hanging like some other companies have done – even if that means I have to meet the drivers close to their home and work with my own two hands.”

Auxiliary power units just got a bit cheaper.
Sunday, October 12th, 2008Well, not exactly the unit itself. Part of the Wall Street bailout bill includes a provision to eliminate the FET or federal excise tax on auxiliary power units installed on new tractors. The FET rate is 12% so a potential savings of $1200 is realistic.
Since more truck buyers will be buying new APUs, this also means that we should see a slight increase in used trucks with their anti idling gear in place. Good news all around.
Steam engine proposed as an anti idling unit.

Cyclone Power Technologies Unveils Eco-Friendly Auxiliary Power Unit at Commercial Vehicle Show
POMPANO BEACH, FL, Oct. 6, 2008 — Cyclone Power Technologies Inc. (Pink Sheets: CYPW) will introduce its production version Waste Heat Engine at the SAE Commercial Vehicle Engineering Congress and Exhibition, commencing Tuesday, Oct. 7, outside of Chicago, IL Cyclone’s Waste Heat Engine (WHE, pronounced “we”) is a steam-driven engine capable of producing up to 10kW of electricity from the exhaust of commercial trucks and recreational vehicles. This auxiliary power can charge batteries, run small-scale refrigerating units and support in-cab comfort appliances while the prime mover engine is running. When the primary engine is off, the WHE can run on a multitude of fuels, including diesel from the main fuel tank, or CNG, propane or even clean coal powder from a secondary tank.
“We believe that our solution is more economical and environmentally friendly than other auxiliary power units on the market,” stated Harry Schoell, CEO of Cyclone and inventor of the WHE.
A substantial portion of the energy produced by an internal combustion engine is lost through exhaust heat. The WHE was developed to harness that wasted resource and transform it to usable energy. This reduces fuel consumption and, consequently, greenhouse gas emissions. When running on fossil or bio fuels, the WHE operates at low pressures and temperatures, which virtually eliminates the production of nitrogen oxide and harmful particulate matters.
Engine idling is a major problem in the commercial trucking industry. A typical long-haul truck idles for an estimated 1,800 to 2,400 hours per year when parked overnight at truck stops and other rest areas. In fact, U.S. Department of Transportation regulations require 10 hours of rest for every 11 hours of driving. Commercial trucks alone consume an estimated 1 billion gallons of diesel fuel annually during overnight idling, costing well over $4 billion and emitting millions of pounds of dangerous greenhouse gases into the air.
Cyclone will showcase the WHE as attached to a commercial truck engine’s exhaust system and three additional fuel tanks: one for diesel/gasoline, one for CNG, and the last for clean coal powder. The company expects this engine to be ready for production by mid 2009.
Wisconsin’s extends it’s diesel truck idling reduction program application deadline.
Thursday, September 25th, 2008The Wisconsin Department of Commerce has extended the deadline for it’s idling reduction program until December 1st 2008.
The slowdown in the economy, high fuel prices, and a high initial cost of idling reduction units may be the reasons that the grant money has not been utilized as early as in years past. While the program does reimburse companies and owner-operators from Wisconsin up to 50% of the cost of idling reduction units and idling alternatives, the owner operator or company must pay for the units up front and report on their idling habits before checks are sent.
EPA announces the distribution of the first $3.4 million of it’s Diesel Emissions Reduction Program.
Thursday, September 25th, 2008Press Release
(Washington, D.C. – Sept. 24, 2008) To improve air quality and protect public health, EPA today announced the first $3.4 million in funding for clean diesel projects under the $50 million Diesel Emission Reduction Program. This campaign makes awards to save fuel and lower greenhouse gas and diesel exhaust emissions from the country’s existing fleet of 11 million diesel engines.
“This fall, EPA is paving the way for clean diesel progress,” said EPA Administrator Stephen L. Johnson. “These grants encourage technologies that will help truckers save over $72 million in fuel costs per year and lower their environmental impacts.”
Three organizations received $3.4 million for small trucking firms to lower fuel costs and shrink their carbon footprints through innovative loans and rebates. The organizations receiving funds under the national diesel program are: the Community Development Transportation Lending Services, Washington, D.C.; Cascade Sierra Solutions, Oregon; and Owner-Operator Independent Drivers Association, Missouri.
EPA will also begin disbursing $14.8 million for State Clean Diesel programs. All 50 states will receive funds, and 35 states will put matching resources toward the program. Later this fall, $27.6 million in grants will be distributed by EPA’s ten Regional offices. Finally, grant awards for emerging technologies totaling approximately $3.4 million will be announced this winter.
Diesel engines emit 7.3 million tons of smog-forming nitrogen oxides and 333,000 tons of soot annually. This pollution is linked to thousands of premature deaths, hundreds of thousands of asthma attacks and millions of lost work days. EPA’s new diesel engine standards will significantly reduce emission from newly manufactured engines, and these grants will lower emissions from the diesel engines already in use through clean innovative technology.
OOIDA’s special report on it’s role in the clean diesel program
The perfect APU (with current technology).
Sunday, September 14th, 2008After all of the research that I have done to get this site up and running, I have come to see the advantages and shortcomings of a lot of idling alternatives. I have come up with the characteristics of what would make the best APU. It would surely be expensive, but if you are spending enough money to buy a small car, you want it to be right.
- Start with a Kubota engine. Great dealer network, a long service interval, and a reputation for reliability. Optionally 2 cylinders for a liteweight model or a 3 cylinder for a no comprimise model.
- A 6000 watt generator. This would give you plenty of power for a rooftop A/C if you have a large sleeper.
- The APU would be tied into the main engine but would have shutoff valves in case one or the other springs a leak. Optional separate APU radiator and Webasto/Espar coolant heater for those who don’t like the engine tied in.
- Auto start/stop for cabin temperature, low battery, block temperature, and a day/hr timer. All of these settings would need to be ajustable.
- Heat would come from a Webasto or Espar diesel fired heater. These are incredibly efficient at around .04 gallons per hour and their reliablity is bankable.
- A/C would come from a rooftop unit, back of wall unit, under bunk unit, or under floor unit. Some of these are not commercially available, but the technology exists for a company like Dometic, Carrier, or Coleman to easily create one. This would eliminate the need for ducting, one of the biggest capacity thieves of current A/C units. Any one of these units should be repairable cheaply or completely replaceable for under $500.
- As many parts as possible would be non-proprietary. You should be able to replace the alternator, air filter, oil filter, fuel filter, and belts from Wal-Mart or any auto parts store in under one hour.
Because of the non-proprietary nature of the APU service locations would be plentiful. It would also be simple enough that a owner or general service person could work on it. The only proprietary part on the unit would be the electronics.
I know that it isn’t possible for a given APU to be perfect for everyone, but with a non-proprietary, open approach, additions or options would make the purchase the best choice for more situations.
Some tips to get better heating and cooling from your HVAC unit.
Friday, September 12th, 2008Who doesn’t wish that they could get better heating and cooling from their APU or battery powered anti-idling unit? Those of us with large sleepers and dark paint know that when the weather gets hot, their APU is going to run 24/7. My friend Gary posted some great tips in the forums about how to give your HVAC a boost.
I purchased a Pro Heat APU last year. I have a black Volvo 770 so it takes a lot of air conditioning to cool it off, the sun is not my friend in the summer. I have been in the Pro Heat shop a few times and have always asked if there was anything I could do to improve the performance of the air conditioning. Always the same answer, no.
If I was in 90 degree heat in the sun the Pro Heat just would not do the job. Even with the curtains closed it could not keep the sleeper cool.
One day my brother in law (Joe)was over to my house and had remembered me telling him about the problem he asked if he could take a look, he is trained in heat and air conditioning . Within five minutes he pointed out what he thought the problems were.
1:On the install they had cut two, three inch holes for my cold air return when the Hvac unit has a twelve inch by twelve inch opening that it draws from. My Hvac was starving for air.
2:The air ducts were routed through my tool box area and were not insulated. Joe said that I was losing a lot of cooling btu’s through the walls of the ducting system.
3: Joe pointed out that on my set up they had cut a hole in my existing truck duct system and just stuck one of my APU ducts in there and that again I would lose cooling btu’s by having to cool the duct system and that the cool air would naturally fall back into the truck a/c unit. Also, the way they just stuck the APU duct into my truck system the truck system had been partially blocked which decreased my truck a/c performance.
4:Joe pointed out that even though the truck has electric shut off valves on the input to the trucks heaters that there is always back feed which will put some warm water from the engine back into the truck heaters making the cab harder to cool.
So, I purchased a roll of four inch insulated hose from Menard’s $28.00 bucks and just slid it over the factory three inch APU hoses.
Then I pulled the APU duct out of my trucks ducting system and made a new vent for it then patched the truck duct. The new vent cost $6.00.
After that I went to the hardware store and bought a standard twelve inch by twelve inch return vent, Where they had cut two tiny three inch cold air return holes I cut an eleven inch by eleven inch hole and covered it with the vent I had purchased at the hardware store, cost $10.00.
Finally I bought two inline valves and installed them in both the input and output of the truck heater. Cost $10.00
The result… Well, I am in Richmond,VA it is 91 outside and my truck is sitting in the sun. Before I made the changes Joe suggested the Pro Heat would never shut off and would not keep me cool. Now, it cycles as it should, shutting the APU off when the cab temp is down to my desired temperature. Then it starts back up when the cab warms up.
What surprises me is that this multi million dollar company goes through so much effort to build a good unit, then does not properly install them to work up to their potential.
Happy APUing
If you have some tips to add, post them in the comments, in the forums, or even better, do both.

Wisconsin APU grant program applications due by August 8th.
Wednesday, July 30th, 2008The program to reimburse Wisconsin carriers 50 percent of the cost of an idling reduction unit is approaching it’s deadline for applications. The Department of Commerce began accepting applications on July 1st and will close the acceptance period on August 1st. Of the $2 million dollars set aside for the program, $500,000 will be reserved for small trucking companies.
The program was created by the Governor’s budget bill, 2005 Wisconsin Act 25. Under the program, Commerce provides grants to freight motor carriers (common, contract and private motor carriers) headquartered in Wisconsin to purchase and install idling reduction units for newer truck tractors. Idling reduction units provide an alternative source of power used to heat, cool, or provide electricity to the cab or other parts of a truck in lieu of operating the truck’s main drive engine to power these services. The use of idling reduction units on heavy-duty diesel trucks saves fuel and lowers air pollution emissions. The program will award grants through June 2011.
You can check out the program at the Wisconsin idling-reduction grant site.
Thermo King Launches Extreme Arctic Kit for TriPac System
Monday, July 28th, 2008(Minneapolis – March 27, 2008) – Thermo King is pleased to announce the launch of the Extreme Arctic Kit for their TriPac Hybrid Auxiliary Idle Reduction and Temperature Management System. Lower operating costs and longer engine life are two of the driving factors behind the development of Thermo King’s Extreme Arctic Kit for the industry’s leading anti-idle solution, the TriPac system. Numerous studies have shown that the majority of mechanical engine wear (up to 90 percent) occurs during engine start-up. Cold weather startup is potentially even more damaging as oil pressure will vary widely during the first several minutes of a cold-engine start.
Thermo King’s Extreme Arctic Kit includes both a coolant and oil heater, which ensures that not only are cold weather starting problems a thing of the past, but that engine wear is no different than during warm weather starts.
When the TriPac system senses a coolant temperature below 30° F, the system automatically starts the TriPac engine and engages the coolant and oil heaters. The TriPac engine then circulates the coolant between the engine block and the TriPac, continuously monitoring the coolant temperature until it reaches 60° F. With the Extreme Arctic Kit, the TriPac system not only keeps the driver comfortable in the coldest of environments, it now makes sure the tractor starts easily every time with minimal wear and tear. The Extreme Arctic Kit is available now at Thermo King dealers nationwide.
Thermo King’s TriPac DPF Gains CARB Approval
Monday, July 28th, 2008(Minneapolis – June 10, 2008) – Thermo King’s diesel particulate filter (DPF) for its TriPac Hybrid Auxiliary Idle Reduction and Temperature Management System has been approved for use by the California Air Resources Board (CARB). The DPF is designed to meet TriPac APU emissions requirements required by CARB for APUs running in California that are attached to class 8 tractors with 2007 or newer engines. In addition to being designed to meet CARB regulations, the TriPac DPF offers several other features important to drivers and owners. Regeneration, the process of burning off particulate matter trapped in the filter element, takes place during normal driving hours with no disruption to the driver during rest periods. Plus, extended APU runtime between regenerations assures minimal driver involvement.
TriPac APU customers can be assured that the TriPac DPF does not reduce fuel economy and will place no extra strain on the APU, nor will it alter scheduled maintenance intervals. As another environmental benefit, the filter also reduces engine noise, making the already-quiet TriPac system even quieter.
Because Thermo King is committed to delivering excellent performance to its customers, the company has gone beyond the testing required by CARB and performed additional testing to ensure that the DPF meets the high standards demanded of all Thermo King products.
Other benefits include flexibility for all customers, as the DPF has nine different mounting options, based on vehicle considerations, enabling easy installation on most modern tractors despite the trend of less available frame rail space. The DPF is also designed for minimal maintenance, which reduces costs and downtime.
“Beyond meeting the emission requirements as set by CARB, we were very conscious of our customers’ requests not to add additional maintenance to their fleets or require the stocking of different types of lubricants than what they already use in their equipment,” says Tom Kampf, APU product manager, Thermo King.
The TriPac DPF is the example of Thermo King’s commitment to developing the latest in environmentally-friendly Green technologies.
The DPF is now available as an aftermarket or original equipment option to support both current and new customers and is backed by the Thermo King Dealer Network, with more than 200 locations nationwide.
Navistar offers new Fleetrite APU
Saturday, July 26th, 2008Truck owners and fleets can reduce fuel usage, lower emissions and comply with new anti-idling laws with the new Fleetrite® Auxiliary Power Unit (APU), a retrofit product introduced from Navistar.
“A Class 8 truck burns a little more than a gallon of diesel fuel per hour idling, and a long-haul sleeper idles around 2,400 hours per year,” said Ron Sandefur, vice president, aftermarket purchasing and products, Navistar Parts Group. “Figure in the high price of diesel fuel and the result is a lot of wasted money.
“With a Fleetrite APU, truck owners can reduce fuel usage to only 0.3 gallons of fuel per hour while idling, or up to 80 percent less than normal idle, saving fleets and owner-operators up to $8,500 a year and 1,920 gallons of fuel annually per truck,” Sandefur said.
The Fleetrite APU is an auxiliary power unit designed as an aftermarket retrofit for all makes and models of Class 8 trucks. Powered by a 14-horsepower, 2-cylinder Caterpillar diesel engine, the unit takes the place of the engine under the hood to efficiently provide driver necessities including heat, air conditioning and power for electronics while the truck is idle.
“Even with the high price of diesel fuel, drivers don’t have to sacrifice being comfortable while resting for the night or waiting for their trailers to get loaded or unloaded,” said Jan Penrow, product manager, aftermarket products, Navistar Parts Group. “The Fleetrite APU delivers air conditioning, heat and power quickly and most importantly, without using a lot of fuel.”
A simple and non-intrusive design, the Fleetrite APU only uses the truck’s battery power and fuel tank to start and power its electronic system and run the engine.
The HVAC system of the Fleetrite APU delivers the most cooling and heating capacity on the market, ensuring drivers will be comfortable in any temperature conditions. A 60-Amp DC alternator charges the truck’s battery while a 6-kW generator powers appliances and the engine-block heater. Mounted in the cabin of the truck, the control panel features a large LCD screen and easy-to-use single-touch menu functions.
Two CARB-compliant Fleetrite APU models are available depending on the truck’s manufacture date. For 2007 or newer trucks, an APU model is available that requires a diesel particulate filter (DPF) for CARB compliance.
International dealers also offer other anti-idling solutions as aftermarket retrofits including NITE battery powered systems, Espar cab heaters, Webasto cab heaters and Webasto C5 truck heating and cooling units, and Autotherm® energy-recovery units for day-cab trucks.
Navistar also will offer a factory-installed APU called MaxxPower as an option on new International Class 8 trucks beginning later this year.
