The Low Humidity System LHS-600 achieves and maintains extremely low humidity levels in enclosed environments through desiccant dehumidification. It removes moisture at 16 lbs/hr nominal capacity (75°F, 50% RH input) and delivers air at -40°F dewpoint or lower. The system operates continuously with automatic PLC control, dual centrifugal fans, and selectable on/off or modulating humidity control. An all-welded aluminum cabinet with insulated air chambers and a monolithic silicate rotor with glass fiber reinforcement provides reliable, low-maintenance operation across process airflow rates of 300–1125 scfm.
