comfort guard apu
 

Does anyone have any experience with the Comfort Guard APU? It has a Cummins engine in it. I was wondering if its a quiet running unit?

It's a Kubota engine not Cummings.

It's a cummins engine not cummings.

Ya, whatever. Still a Kubota in there.

Steve what unit did u end up buying for your truck?

I bought the Rigmaster and very happy with it. I'm sure the Comfort Guard is just as nice. I know it's quieter than my unit.

I was also wondering which unit is the quietiest unit out there?

I don't think it really matters. They are all pretty quiet when your inside the cab. I've also seen people run the muffler out to the very end of their tractor with another muffler and it's really quiet.

have u heard it run? or u taking a wild guess?

I've heard the Comfort run a bunch of times and it's the quietest out of all of them.

I wonder how does it compare to the thermo king apu? I have read that thermo is the best and the questiest wish I could hear them both side by side...

thanks steve

The tripac doesn't provide much power though.

Really? when u say power u mean cooling and heating? or power to run stuff in the cabin?

I have a Rigmaster, had to replace the muffler and the flex exhaust manifold. Other than that no problems. Rigmaster is working on a newer exhaust system to quiet it them down to below 80dB while under A/C load

It has it's own AC compressor, 13,000 btu's, should be more then enough.

It comes with an espar air heater, instead of the generator making the heat to heat the cabin. The espars are very efficient.

To keep the engine warm, the tripac is hooked up to the cooling system.

All it has for power is 12 volts, 65 amps, which is 780 watts if you do the math.

But it is REALLY efficient, only comes on when needed

Yes, but you're talking about 12 VDC.

The thermoking produces ZERO 120 VAC.

So you're restricted to a mere 780 watts with the tripac unit. Any more and you start draining batteries.

The other 2 units produce their own 120 VAC, as well as 12 VDC.

So with the tri pac if I still decided to use this unit I would need a powerful inverter connectted to maybe dry cell batteries and once the power is used up the tri pac would recharge them. could this setup work?

Here is an article on them...I read it in a trucking magazine and just found it online as well.....the cummins unit had its warranty backed service interval changed from 500 hours up to 1000 hours...i am sure this will be a big selling point for it.

Wow! thanks this is good news I was leaning more to the tri pac beacause of the 1000 hours service but now this is a big plus for me.. also there a Cummins Dealer that install and service this item 3 miles from my house..

thanks for the article

You should read the specifications for yourself on the units your interested in. A lot of the info here is wrong.

The Tripac does not provide 780 watts of power. Allan is confused about that. They are talking about the alternator which is only for charging your batteries. The Tripac does offer 110 but it's an optional feature.

The Rigmaster maintenance interval is also 1,000 hours. That's why Tripac followed them with the same idea. They both basically increased the oil pan from 1 quart to 3 quarts.

Rigmaster by default provides 6,000 watts of 110 power, 20,000 btu A/C and 12,000 btu heater. It also has the auto start and auto stop and only comes on when needed.

You need to read about all the units out there. They vary so much in functionality and price so you need to decide which is best for you.

Yes steve I will check all the information and also check the watts and amps on the items I want to power while on the road then decide which unit is the right one..

thanks for the information

I am not confused at all. The tripac also has optional inverters, but you could supply your own. It would all be connected to the same circuit. And with the 110 it would only supply 780 watts, any more usage then that it would start draining your batteries, since it's all the same circuit.

Sorry, I actually went to the dealer and they can outfit the unit with up to 3,000 watts. The 65 amp you were talking about before is the alternator used just for keeping your batteries charged.

Yes you're right, but it can also be used to power household stuff with an inverter. Since it's all connected.

Upgrade the unit to 3000 watts... 12 volt or 120 volt or what?

I just read up on the unit and I didn't realize Tripac does not offer 110 off the unit itself. I just assumed that was an option and now realize the dealer was just offering to sell an inverter. That's weird?
