Thermo King
Spectrum® SB 30 Multi-Temperature System



SPECTRUM multi-temperature systems lead the way in advanced cargo protection.

Thermo King’s temperature control systems for trailers usher in a new era in transport refrigeration. Fueled by growing concerns over temperature inaccuracy and contamination of perishable food products, governments and customers worldwide are demanding tighter control and more accurate monitoring of temperatures throughout the “cold chain.” Regulatory bodies have become industry partners in this effort, creating the Hazard Analysis Critical Control Points (HACCP) as a means of control.

At the same time, transport companies continually seek greater fuel efficiency, along with systems that run quietly and are easy to operate. The new SPECTRUM system meets these new challenges head-on, by incorporating the latest technology and innovation into the industry’s most advanced temperature control system. Reliability, temperature control, fast pull down, ease of use, fuel efficiency, quiet operation ... they’re all here. The SPECTRUM systems do it all ... and nobody does it better.
