Refrigeration Systems / Johnson Mechanical Blower Refrigeration Options

ThermoKing Corporation and Carrier Transicold are Johnson’s primary suppliers of forced air refrigeration systems. Both systems are designed with maximum flexibility to accommodate the various temperature control needs of medium and large truck bodies and trailers.

These systems cool by transferring heat from inside the truck body to the exterior. Consistent uniform airflow is circulated around the product to pick-up heat. The air is then lowered in temperature as it passes through the evaporator coil. The heat is absorbed from the air by the refrigerant gas in the evaporator, and is transferred outside the body into the atmosphere.

	Mechanical	Cold Plate
Operating Application	Extended road time	Daily runs 10-12 hours
Initial Cost	Higher than plates	Lower than mechanical
Operating Cost	Subject to fuel costs higher maintenance	Typically lower electric rates, less maintenance
Effective System Life	10 years with proper maintenance	Life of truck
Reliability	Failure = Loss of product protection	Product protected up to 24 hours
Down Time	Down time limited to pre-cooling	Plate recharging requires 8-10 hours down time
Maintenance / Complexity	100-1500 hours scheduled maintenance required	Low maintenance required
Temperature Response	Quick response to temperature recovery	Dedicated application, slower temperature recovery
Environmental Compatibility	Exhaust discharge, higher noise levels	No pollutant discharge, quiet operation
