3 in 1 dehumidification dryer machine combines drying, dehumidifying, and the two-stage conveying functions in a single unit. They are suitable for drying hygroscopic engineering plastics, such as PA, PC, PBT, PET, and so on. It can reach dew point-40℃ under ideal conditions. Features of dehumidifier air dryer 1) Microcomputer controller adopted. 2) This HDC integrated conveying dehumidifier is equipped with an imported honeycomb dehumidifying rotor from Proflute, a Swedish company. 3) Micro-motor designed with the latest pendulum structure for the easier achievement of dew-point. 4) Suitable for use on engineering plastic materials with strong absorption ability such as PA, PC, PBT, PET, etc. 5) Integration of three functions in one machine, namely dehumidifying, drying, and two-section material conveying. Three-section or four-section material conveying is also optional. 6) Air blowing tube designed under the heat-preserving drying barrel to effectively avoid heat dissipation and improve drying efficiency. 7) Using dual-fin cooler design to ensure a lower return air temperature and dew-point. 8) Equipped with material conveying, recycling, and regenerating filter to keep the key components such as the fan and honeycomb from dust contamination. 9) The conveying system contains a material cut-off valve to make sure no remains in the tube. 10) Optional dew-point meter with real-time display of dew-point detected. 11)With a recyclable and resettable filter to make sure the honeycomb is not contaminated. 12) A thoughtful multiple security devices built-in. 13) Clear fault code display.
