The SD-H series honeycomb dehumidifiers are mainly used to dry hygroscopic engineering plastics. A honeycomb-rotor is used in this series to offer effective drying. We offer two types of honeycomb rotors: H4 and H5 models that, under ideal conditions, can supply dehumidified dry air with a dew-point down to -40°C and -50°C respectively. The SD-H series offers accurate PID temperature control as standard, with LCD touch screen and dew-point monitor as optional features. The range comprises 14 models of honeycomb dehumidifiers, the largest of which can provide dry air up to a volume of 3000m³/hr.
