Thermo King has introduced its Spectrum SB multi-temperature system with the SmartReefer2 (SR-2) controller for trailers. The company also presented the latest in freeze protection for temperature-sensitive cargo: the Heat King unit.
The Spectrum unit is designed to achieve temperature balance in up to three different zones with various configuration possibilities. The Spectrum S-3 remote evaporator, designed with high airflow and large capacity, complements the Spectrum host units, making each temperature zone act like an individual trailer. Thermo King’s Smart Set, designed to offer precise temperature control, facilitates reduced fuel consumption at all operating ranges; cool, moist air circulates throughout the entire cargo area, thereby keeping product dehydration to a minimum and allowing produce to be delivered in the freshest state, according to the company.
EMI-3000, Extended Maintenance Interval, includes a special 12,000-hour coolant and high-grade mineral oil to facilitate extended service life. Optional rear remote control and electronic door switches also are available. The hybrid model 50 units offer electric-to-diesel-switching as standard. All Spectrum SB multi-temperature models come standard with Whisper quiet technology and feature biodiesel-compatible engines.
