Reefer in winter

the reefer unit can be set at whatever temperature you need it to be at......running produce in the winter you set your reefer at the temp required to keep it fresh...anywhere from like 35-45 degrees depending on the produce. If you need to run frozen during the summer no worries just drop the temp to below zero and away you go

 

you got it ......it sure can......you can freeze stuff or warm it up......very rarely have I had to set the reefer warmer than 50.....and usually I only set it at 50 with a load of bulk potatoes during the coldest days in the winter

 

Banana's like 60 and I'll set er around 61-62 depending on the outside temp.

If it's that cold supernaut, I'll run the reefer even empty.

 

A reefer unit will do whatever it takes to maintain the temperature it's set at.

It will heat a perishable load to 45 degrees if it's -22 outside. Many of today's units are sophisticated enough to even monitor the outlet air temperature so they don't freeze the top row of open produce to cool the whole load.

For example, if you had a load of mushrooms in open flats, and the rear doors were open on an 80 degree Phoenix day, it will keep the outlet air at 35 degrees until the unit achieves set temperature instead of blasting 5 degree air out to cool it quicker.

If this wasn't monitored, the top row of produce would have frost crystals on it, and ruin the product.

 

I haul not a lot but quite a bit of beer, mostly kegs but a lot of cans as well. If its -20 degrees out, the reefer is running full boar heating the beer or other beverages to usually around +38 to +40 to keep them cold but not freezing. I was always curiouse what a keg of beer freezing and blowing up would look like? Imagine it be a pretty good explosion.

As said above. The Thermo kings we run will cool the trailer down to -20 degrees Fahrenheit, and heat them up to I think +90 degrees Fahrenheit. Goodyear tires probley all tires have to cure for a certain amount of time at somewhere around +80 fahrenheit otherwise if they get cool, it does something bad to them I dont know what, so if the factory is in a hury to get tires out they get hauled by reefer to a heated warehouse untill the curing proccess is over and they can be shipped by however means to all the customers.

 

So I just learned today the all temperature in a BOL are Fahrenheit unless otherwise stated. I hopes this help others new drivers

 

So I’m wondering let’s say I set the reefer to +34 cycle mode and it for example 10 degrees outside. Will the reefer allow the load to to dip in to freezing temps before it turns on to heat it? That’s my concern. If a load bill says a range of 33-40 you can set it to cycle but it’s not supposed to freeze.

 

No it should not let it dip that low.

Outside temps that low I would run on continuous and make sure your fuel is treated. A froze up reefer unit is a royal pain to get started again. If you buy fuel in the southern states during winter time make sure you treat it before you get back north. That applies to both truck and trailer.
