Subzero temperature load

You may as well run it continuous. I has a load going to a Domino's Pizza warehouse. It was toasty outside. It took forever to get the product down to 10 below. The reefer ran for about 8 hrs before it finally cut off. Then it cut on every 30 min if that. Its better to pick up at the places where you the shipper can open your doors from the inside. The. You don't lose much coolness if you had to precool.

 

Same here, my reefer gets to -10 after sunset, during the day I set all frozen loads to -1 to keep rpm low, weird thing is the supply air temp is lower temp than when its on high rpm.

 

That's good thinking about keeping the rpm low, I'll take that as a tip
