DSH Mould Dryer Series

The DSH air dehumidifiers are the most innovative solution to the problem of condensate on injection moulds and blowers.
Air is dehumidified with a desiccant rotor system that brings the air dew point to -10°C. With airflows from 800 to 3000 m3/h, they can be mounted on one or more processing machines.


  • Microprocessor control of the machine, leading to a constant dew point with PID regeneration control.
  • Filtration through an easily accessible and cleanable panel filter.
  • Air is pre.cooled by an exchanger using low temperature water (7-10°C). Condensed water is expelled by a pump with in-built floater.
  • The high-head fan sends air to the high-efficiency absorbent rotor providing a stable process also in tropical climatic conditions with temperatures of up to 45°C and humidity up to 90%.
  • A post-cooler may be installed to reduce the outflowing air temperature
  • RS485 ModBus interface


  • Dew Point device with alarm.
  • Touch screen colour operator panel
  • Clogged filter pressure switch


  • Increases productivity by reducing the cycle time.
  • Constant process in all climates
  • Absence of waste due to mould moisture.
  • No mould corrosion risk and subsequent maintenance.
