Desert Aire has introduced the ExpertAire™ LW Series of dehumidification solutions for low-temperature environments. The company says the ExpertAire™ LW Series is ideal for facility owners and HVAC system designers striving to keep space humidity under control when air temperatures are low. The dehumidifiers are designed to control low-temperature conditions in ice arenas, water treatment plants, pumping stations, food storage and processing facilities, and the drying rooms of grow rooms and indoor farms. ExpertAire™ LW Series solutions meet operating conditions from 45°F to 80°F (7°C to 26°C). Desert Aire offers ExpertAire™ LW Series solutions in capacities ranging from 3 tons to 15 tons.
Key to the extended performance of ExpertAire™ LW Series solutions in low-temperature environments are evaporator coils engineered specifically for low ambient moisture removal. Desert Aire then adds appropriate components to ensure long operating lives of the evaporator coils and the entire systems. The company says these components include user-definable timers that will initiate defrost cycles of the evaporator coils if needed. The need to defrost is determined by monitoring suction line temperatures and then activating defrost cycles when they drop below 32° F (-1° C).
