Thermo King SB-210 Trailer Refrigeration Unit

The Thermo King SB-210 is a foundational model in trailer refrigeration, recognized for its widespread use and reliability across North America. Its ubiquitous presence ensures excellent parts availability and service support through the extensive Thermo King dealer network and independent repair shops, making it a practical and economical choice.

This single-temperature, nose-mount unit is powered by the robust TK486V four-cylinder diesel engine and utilizes R-404A refrigerant. It’s designed for genuine frozen capability and operates using an SR-2 microprocessor controller. While standard, options like an Electronic Throttling Valve (ETV) and a 50-gallon fuel tank were commonly integrated.

Offered at $5,000 for inspected used units with confirmed engine hours, the SB-210 provides a cost-effective solution for trailers ranging from 48 to 53 feet. It is important to distinguish it from the later SB-210+ model, which introduced features like ETV as standard and the SmartPower electric standby option for enhanced efficiency.
