General Information

This Thermo King Advancer unit is a one piece, self-contained, diesel/electric powered cooling/heating trailer unit. The unit mounts on the front of the trailer with the evaporator extending through an opening in the front wall. It features a fully programmable microprocessor controller designed exclusively for transport refrigeration applications, all-new DDE (Diesel Direct Electric) architecture, a quiet running Thermo King diesel engine, and a Thermo King X430 reciprocating compressor.

  • A-360: The all-round Advancer unit includes a powerful engine, fully variable airflow and precise temperature control.

  • A-400: The new standard in trailer refrigeration comes with electronic engine speed control and with extra features to boost fuel efficiency.

  • A-500: The flagship Advancer unit that offers the highest level of fuel efficiency, refrigeration capacity, and temperature management.

  • A-500 Whisper Pro: A top-of-the-range PIEK certified Whisper™ Pro version which complies with the most stringent noise abatement standards. Features a dedicated controller which monitors the time and GPS position to force the unit into PIEK mode.

  • A-500 Spectrum: The flagship Advancer unit that offers the highest level of fuel efficiency, refrigeration capacity, and temperature management, now with Multiple trailer compartments.


  • Cooling, heating (hot gas) and defrost (hot gas) on engine operation and electric standby operation.

Single Temperature Units: Power is provided by a water-cooled, direct injection diesel engine. A centrifugal clutch transfers power from the engine to the compressor. Belts transfer power to the fans and alternator. During electric standby operation, an electric motor drives the compressor, fans and alternator using belts. The centrifugal clutch on the engine isolates the engine from the compressor during electric operation.

Multi-Temperature Units: Spectrum model systems consist of a host unit with a single evaporator and one (or two) remote evaporator units. The host unit contains the diesel engine, compressor, system controls and an evaporator. Refrigerant lines and wire harnesses connect the host unit to the remote evaporators. Several compartment configurations are possible. The temperature in each compartment is maintained by a separate controller (except when the unit is set to control at a single temperature). The systems are flexible enough to allow each compartment to be set at any temperature.

NotaRemote evaporator fans are powered by separate electric motors.
