Temp on empty trailer

It does not matter what the outside temp is provided everything is in order. Particularly the integrity of your trailer. You can usually get down to -20 after a period of some hours inside that thing ready to accept a load. The trailer knows what the outside air temperature combined with the heat index is. And will do it's best to meet your set point. Ive had trailers working in a apparent 145 to 160 degree environment some days at the catwalk.

What you cannot do is chill 80 degree product to -20, it will use up so much time and burn all of your money trying to do it.

 

If you are trying to cool the trailer to a temperature to load 70,000 dollars in say Ice Cream, Frozen. A few gallons of fuel is the least of your anxiety. Cool that thing.

 

I think any seller of a refer will understand your need to test the unit and won't have any issues with you running it for a few hours. My refer will burn about 9 to 10 gallons in a 24 hour period set at -10 continuous in the summer time. Just saying.

 

If I was selling a trailer say for 40,000 dollars (Pulling a price out of a hat...) to you, and you aint happy until you can see first hand what it can do to cool... let it run I say. The fuel loss aint nothing.

It's a lot better to prove it to you in actual cooling than to kick the tires like a shyster salesman trying to con and pressure you into buying a trailer you know nothing about.

 

Buy an TK SB 230 or SB 330.Other then the head gasket issue they are easily the best reefer ever made.

 

They're good too,just make sure the exhaust manifold isn't cracked before you buy it. It's alot of work to replace it.
