LCS™ is available with either a single or dual refrigeration circuit. The refrigeration circuit includes a hermetic scroll compressor. These durable, heavy duty, fully welded compressors have no gaskets or seals, eliminating the possibility of refrigerant or oil leaking into the controlled space or environment. Scroll compressors also bring a combination of reliability, efficiency, and improved system sound performance. The refrigeration circuit includes built-in compressor overload protection, crankcase heater, filter drier, sight-glass, adjustable expansion valve with external equalizer, low pressure override timer (air cooled units), manual reset high pressure control, and compressor short cycle timer.
Water/glycol cooled units include a plate fin condenser sized to provide the required capacity for heat rejection with minimum water/glycol flow and low total pressure drop. Head pressure regulating valves control the condensing temperature and maintain required capacity at various water/glycol flow rates and temperatures.
Air Cooled with Remote Outdoor Condenser
A wide range of outdoor condensers are available. Condensers are manufactured by Data Aire and sized to meet heat rejection and ambient conditions as required. The industrial duty design includes galvanized corrosion resistant housing, aluminum finned copper tube coils, coated fan guards, energy efficient thermally protected direct drive motors, and variable fan speed control on lead motor for proper control down to -20° F ambient temperatures. Additional fan motors are controlled with ambient thermostats.
Air Cooled with Outdoor Condensing Unit
When compressors are required to be out of the controlled space, LCS™ is available with a remote outdoor condensing unit. The condensing unit includes hermetic scroll compressor(s) with built-in overload protection, crankcase heater, filter drier, sight-glass, and condenser coil. The coil is constructed with copper tubes and aluminum fins. The housing is galvanized steel with vertical air discharge. The condenser fan motor is variable speed type for head pressure control down to -20° F ambient temperatures. Additional fan motors are controlled by ambient fan thermostats.
Water/Glycol Cooled with Remote Outdoor Dry Cooler
Remote outdoor dry coolers are available in a variety of sizes. Each dry cooler includes galvanized corrosion resistant housing, aluminum finned copper tube coil, coated fan guards, surge tank, pump contactor, and energy efficient thermally protected direct drive motors. Dry coolers with multiple motors have cycling control.
