Thermo King
Thermo King Corp. has designed the newest refrigeration unit in its SB truckload series. The SB-400 features the highest cooling capacity at low temperatures and super fast temperature pull down while providing the best fuel efficiency available, the company says.

Technology featured in the SB series includes the MP-VI SMART REEFER controller with the exclusive OptiSet temperature management system, the maintenance-reducing EMI-3000 system, the Electronic Throttling Valve, on-board Data Acquisition System with easy viewing WINTRAC software, Whisper- quiet package, the S-391 screw compressor and a 12,000-hour long-life coolant.

At 100 degrees F ambient, the SB-400 delivers the following unit capacities: the SB-400 has the capacity of 60,000 Btu/hour at 35 degrees F; 40,000 Btu/hour at 0 degrees F, and 30,000 Btu/hour at -20 degrees F.

Equipped with the S-391 screw compressor, the unit uses twin rotor screws to compress the refrigerant to achieve its capacity and an extra suction port capacity booster to generate even higher capacity for deep frozen loads. The S-391 screw compressor has 80 per cent fewer moving parts than reciprocating compressors resulting in a quieter, smoother performance with great reliability and less maintenance, the company says.

An array of performance enhancement options for the SB-400 is available. Thermo King’s exclusive PrimAir bulkhead and unique FlexAir duct system, constructed of “food safe” polyethylene material, distributes conditioned air to all corners of the cargo to ensure total temperature management.
Thermo King’s R:COM option allows remote retrieval of data stored in the unit datalogger as the reefer unit passes by a base station.
