A full range of trailer units that offer greater efficiency, ease of use, and uptime.
SB-Series: Trailer Refrigeration Units
The SB-110+ was introduced at the Mid-America Trucking Show. The reefer unit follows on the heels of the company’s 210 and 310 models but provides a reduced cooling capacity.
This unit is elementary to use and operate, and at the same time it provides the best available technology.
The SB-110 is perfect for dairy and deli operators making shorter trips and in-city deliveries.
Like its more powerful cousins, the SB-110+ comes equipped with the SR-2 controller, which features the industry’s largest temperature display making it easy to read from a distance. The controller is also sloped downward so it doesn’t reflect sunlight and the keypad has been more conveniently located. Also, the SR-2 functions in various languages.
