A NEW TRUCK REFRIGERATION UNITA new truck refrigeration unit is designed to set mechanical refrigeration records for performance, maintenance-free reliability and profit-producing potential. The unit's ‘built-for-transport components’ result in extended maintenance intervals of once every 1,000 hours or twice a year, says R. Pfankuch, marketing manager with Thermo King Corp. The components Featured components include: Fin condenser and evaporator coils. They contribute to heat transfer efficiency by allowing more effective air-wash over more coil fin surface. The coils resist wear, corrosion, shock and vibration because of aluminum fins. Bypass oil filter Long-life silicone coolant hoses Pre-programmed, solid state timer for automatic defrost. Defrost can also be initiated manually. The specs The refrigeration unit is suited for 28-foot straight truck bodies; it has capacity of 25,000 BTU-hour at 35ºF. The unit can hold product at -20ºF, and it distributes air evenly throughout the load, according to the manufacturer. “When we showed this unit for the first time at the Food & Dairy Expo '85, the audience was extremely receptive,” says Pfankuch. The refrigeration unit is ideal for transporting ice cream, he adds. High volume air flow is 1,800 cfm from dual evaporator fans. Air change rate is 1.1 per minute in a 20-ft body. What does this mean? Fast temperature recovery after door openings and accurate temperature control. Fuel consumption can be as low as 30 gallons per hour, depending on ambient temperature, type and condition of the load, loading methods, evaporator airflow restrictions and maintenance of equipment. (An optional control to automatically start and stop the unit by thermostat demand is available, too.) The unit's diesel engine has a 14.1 hp continuous duty rating at 2,400 rpm, thereby delivering the power needed for maximum operating and maintenance economy. The compressor, with 30 cubic inch displacement, has a 50 to 1 compression ratio. The evaporator occupies 23 percent less cargo space than other mechanical refrigeration systems. It is 13 inches high, extends 27.7 inches into the truck body and is positioned next to the ceiling.Three models are available.
