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 system incorporates the latest technology and innovation into the industry’s most advanced temperature control systems, the company says. Featuring the SR-2 controller with enlarged display screen, customers can view cargo temperature and system set point value; all temperature zones are viewed simultaneously, which allows for quick unit checks in the yard. Clear text messages, along with codes, are viewable, and customers have the option to choose between 22 language settings.
  • 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.

  • The Heat King unit is a powerful, forced air heating unit that works on the same basic principle as a car’s heating system, according to the company: A Tier-II, diesel-powered engine heats liquid coolant in a radiator coil, while a powerful blower forces air across the coil and into the cargo area. The result is safe, efficient, dependable heat inside the trailer or container, no matter how cold it gets outside, Thermo King says. The Heat King unit also features a belt-driven alternator designed to automatically recharge the unit’s battery while the engine is running.
  • When operating on high speed, the Heat King’s blower delivers substantial heat output to protect valuable cargo, even in the coldest of ambient temperatures, the company says; when temperatures moderate but remain below the desired product temperature, low speed provides the appropriate amount of heat output, which still protects the cargo and also conserves fuel.
