First reefer load

When in doubt always run continuous! Being that your running frozen pastries I would probably set the reefer to start stop as that stuff won't melt or go bad between temps. -10 is frozen so that trailer would have to get pretty hot for it to go bad.

 

Loading pre-frozen pastries, you can run start/stop. Your temp variable will be less than 5 degrees. No need to waste reefer fuel. That is if your unit is capable of easily maintaining -10.
Just make a habit of every time you stop and get out, check the temp, to ensure there are no problems. Should you develop a fault/problem, the product will maintain a frozen state for 4-6 hours if the doors are not opened.

 

The bills will often state what the shipper "wants" as far as mode. If not, at -10 I would err on the safe side and run continuous at current cross-country temps, but then again if I had a newer unit I would not be concerned with running on cycle-sentry, either. If some of the product just came off the line, it would be wise to run continuous for 6-10 hours to insure a consistent deep cold as the warmer product slowly comes into equilibrium with the set temp

 

shipper or broker will generally tell u what temp to put it on & start/stop aka cycle or continuous.

 

Set it and forget it

 

I pull refers use stop and start the whole time. I pull refers. Only way continous is ice cream at -20

 

frozen loads I always ran continuous, dident see the point in the reefer turning on and off all the time, imo its easier on the unit to keep it running
