Mr. Dennehy has been V.P. of Marketing and Communications with Espar for 9 years. He has played an integral part in working with several levels of government agencies in both the U.S. and Canada to bring awareness to the challenges of idling, anti-idling technologies and the reduction of green house gases. Mr. Dennehy will entertain questions on anti-idling technologies, state regulations and state/province initiatives regarding rebates/incentives and also idling laws and fines within each state.

John,
We are still looking for a viable alternative to Carrier Solara and Thermo-King Heat King for Full Trailer Loads hauling flammables that run in regions that we feel do not require the diesel with heat exchanger design.
Must have DOT exemption.

Well I had to do a little research on this one. I visited the web sites to understand what these units you are talking about did. Essentially they are generator sets that can provide heat and cool if they have too. Smaller gen sets are quite popular in the truck market now as anti-idling devices providing the creature comforts of home to drivers. Some consider them APU's. To answer your question , the only thing I can think of and recommend is using a high heat out put forced air heater like Espar's D8LC, http://www.espar.com/html/products/D8LC.html
It is quite capable of heating a 53 foot trailer and runs very much like your home furnace. It does not have the exchangers like the larger generator units. It does however need a supply of diesel fuel to run.

We recently started watching our idling time very closely and have reduced our numbers greatly but would like to do better. What is the an acceptable percentage time for idling.
|
|
| A. |
|
A few years ago the average idle times were between 40 - 50%, that is and was staggering. With new initiatives and regulations we've seen these numbers come down to around 30-40%, however I know there are fleets who are religious about not idling engines and they have gotten them down to as low as 7-10%. One very large fleet that we have worked with in the past and continue to today has there idle time in at 19% and they are happy about that. So I would say to you that 15-20% would be a good target.

1. We are looking for cab heating gear for construction equipment (loaders, tractors etc) What is our best option. We would also like to include engine heating as part of the system.
2. What is out there for auxilary power units? What types of accessory drag will these take off of the engine?

Your beet option is a combination package of a fuel operated bunk heater (cab) and a fuel operated engine pre-heater. The bunk heater draws fuel from the existing fuel tank and burns it in a heat exchanger, it is the most efficient and economical way of heating mobile applications such as off-highway vehicles. Both the units I'm talking about are independent of the engine.
The engine pre-heater is plumbed into the coolants lines and it has its own coolant pump which circulates the coolant through the block. It is controlled via a timer so can be set in advance so that the engine is warm before operator gets to the vehicle. There is absolutely no strain on the engines with these types of technologies. There is a small amp draw from the battery.
Have a look at this link for a more in depth understanding.

Hi Ken,
I include for you a link that will take you to a monthly publication that outlines available funding by states. It is called National Idling Reduction Network News and is run under the D.O.E.'s Energy Efficiency and Renewable Energy department. A friend of our industry, Terry Levinson publishes it monthly.

OUR COMPANY IS FROM SOUTHERN CALIFORNIA
LAST WEEK THE HEAT WAS AT 120ยบ. OUR TRUCKS TRAVEL IN CALIF.& AZ. WHAT OTHER
ALTERNATIVES ARE THERE FOR EXTREME HEAT AND COLD WEATHER.

There are a number of options for you to choose from, they are; in no particular manner.
Espar fuel opearted heaters, there is no more efficient way to heat your vehicle than this type of technology.
Gen/Set or APU, these systems can do it all, heat , cool, and also offer additional power for your amenities. Downside: Cost and Weight, if you're considering this route think Thermo King "Tri-Pak".
Battery powered A/C units. There are a number of them out there. Bergstrom "Nite" for e.g.
