How much fuel does an APU use?

It varies but between .1 and .3 gallons an hour depending on power and cooling load. As for it being loud have the mufffler checked my thermoking is quiter then my MX13 and vibrates less then any reefer ive used.

 

The trucks I've had use 05. gallon per hour when idling. I don't know about Carrier APUs. I never had to suffer with one of those.

 

THANK YOU!! Most other people think im nuts for dispiseing carrier junk

 

Hmm, the Dynasys and Rigblasters l had were very high RPM under HVAC load. Sounded more like 2 stroke lawn equipment compared to the nice medium idle hum of a TK Tri-Pac IMO. I wouldn't be surprised of they all use almost a gallon an hour also with full HVAC load honestly.

 

I'd like a Carrier but it seems like they are due for an update. Plus the incab box is too tall for the KW sleeper according to some shops l talked to they had to use spacers etc. to fit it.

 

Agreed. I have a dynasys and they claim less than half a gallon per hour, I'm not buying that. My guess is closer to 1 gallon.

Personally if I didn't have a newer emissions truck, I wouldn't have an APU.

 

The tripack on my truck averages around .15 gallons an hour unless its stupid hot and i have the AC cranked to max where its .32 an hour. As for the cooling check if there is a vent under the bunk. Sometimes they get flipped closed and block airflow.

 

It is a nice unit and you save thousands over the main two brands. I had the shore power option so l would plug it in at FedEx where they had plugs for van block heaters. That was nice, free Air conditioning.
