How cold do reefer trucks get?
The average reefer maintains temperatures within a range of about -13 degrees to 77 degrees Fahrenheit. However, there are highly specialized refrigeration units that go as low as -85 degrees Fahrenheit. These reefers are typically used for the transport of items in the medical and chemical industries.
Can reefer containers heat?
Reefers can maintain temperatures up to 30 degrees Celsius (86 degrees Fahrenheit). Whether it heats or cools the air depends on the desired internal temperature. Condenser: Condensers may have air or water cooling, though typically, the industry is using air-cooled condensers.

Can a reefer truck heat?
How many reefer trucks are in the US?
Today, there are more than 500,000 refrigerated trailers in service in the United States alone and each one cost more than $60,000. Refrigerated trailers are called reefers for short by those in the transportation industry.
How long can a reefer container be unplugged?
It is expected that the insulation system of the reefer container is able to maintain internal cargo area temperatures within 1-2 degrees Celsius of the cargo protocol temperature, even with average power disconnection time periods of 1 to 6 hours during its trip.
How much does it cost to run a reefer trailer?
In the US, the annual cost of fuel to operate just the diesel reefer unit is nearly $4000.00. Add annual maintenance costs of over $1500.00 to that and you have a sizable overhead that general truckers do not have. Electric reefer units have less fuel and maintenance costs.
