The ComfortPro APU has a 2 cylinder tier 4 final Kubota engine. The engine has a rated output of 8.9 HP at 2400 RPM.
Is an APU worth it?
On average, we see about a 1 gallon per hour fuel savings of using a APU instead of idling the truck engine. This means that if you idle a truck engine for 1,000 hours per year, you would see a fuel savings of 1,000 gallons. At $4.00 per gallon, you would be saving $4000 per year. In addition, you would save
additional wear and maintenance on your main truck engine and emission system. Use this online calculator to determine what your potential savings may be: https://apuidlecalc.carrier.com/.
Does an APU heat the engine?
Our integrated diesel APU is tied into the truck engine’s coolant system and will preheat the tractor engine, eliminating cold starts.
How long can you run an APU?
The comfortPro diesel APU has a programmable max run time feature. This feature can be set from 2 hours to 24 hours and prevents the unit from running unattended. Once the max runtime has been reached, the driver must push the power button again to restart the APU.
Can you run an APU while the truck is running?
Depending on the installation, the truck and APU engine may be able to run at the same time. If the APU was installed with an interlock, the truck engine must be turned off for the APU engine to start. Battery monitor will override the interlock in the case where a truck alternator fails while the tractor engine is on. In this case, the APU will charge the truck batteries, allowing the driver to reach the next repair shop.
