Green Star Idle Reduction Technology

The fire service is going GREEN! Our exclusive auxiliary power unit (APU) designed specifically for use on fire apparatus will save your department thousands of dollars annually.*

Today's fire service is a constantly changing community organization. We've watched the role of fire departments take on more responsibilities from medical calls, rescues and hazmat incidents for example. Eighty percent of calls fire departments respond to, result in fire apparatus needlessly idling for 10-40 minutes per call.

Frequently Asked Questions
Green Technology

Q. What is an APU?
A. APU stands for Auxiliary Power Unit currently APUs are used on airliners, locomotives, and-long haul trucks to handle the electrical, heating and air conditioning while the vehicle is stationary.

Q. What effect does idling have on Diesel Particulate Filters (DPF)?
A. DPFs are designed to capture unspent diesel soot that occurs while a diesel engine operates at cooler tempatures. Most commonly this happens as diesel engine is at idle. Excessive idling similar to the use pattern of fire apparatus on non-fire calls will increase service intervals above the engine manufacuters suggestions.

Q. How much fuel does a diesel engine use while idling?
A. According to engine manufacturers big block diesel engines use a minimum of 1 gallon per hour idling.

Q. Can a hydraulic generator be used
with an APU?

A. PTO generators cannot be used since the goal of the idle reduction technology is to eliminate the main chassis running.

Q. How much fuel is used by the APU while running under full load?
A. An 8kW diesel gen-set uses approximately one quart of fuel per hour while operating.

Q. How is an APU considered "Clean Diesel Technology"
A. While the APU does not alter the chemical make-up of diesel emissions, it does reduce the amount of NOx (Nitrogen Oxides) that are released overall.

Q. Can the APU power scene lights and provide electical power while the truck is pumping?
A. YES! You can start your APU gen-set from inside the cabin or from the pump control panel similar to a standard generator installation. There is NO need for a second generator as the GREEN Star can handle traditional duties.
