TYPE CRT3000 – CRT 25000


Desiccant dehumidifers in the CRT range, are bigger dehumidifier designed for room air dehumidification and in a quality that matches the CRP range – our flagship.


The chosen proportion between rotor dimension, air flows and connected load, results inndehumidifiers with very high energy efficiency. The advantages of this design are considerable, particularly at low temperatures and low %RH.

TYPE CRT3000 – CRT 25000


  • Cabinet manufactured in stainless steel
  • High capacity, kg/h, at normal temperature and %RH
  • Economic operation, in particular at low temperature and %RH
  • External pressure for process air adapted to the existing installation
  • Cabinet with insulated inlet plenum for process air
  • Pocket filters for process air inlet are standard
  • Stepless temperature control ensures constant regular air temperature
  • Stepless capacity control by using our DCC control and by adjusting the electrical components (accessories)
  • High performance desiccant rotor of silica gel, alternatively molsiev or LiCl
  • Efficient rotor gaskets with long durability
  • Service doors in front of all internal components
  • Operation and service from one side of the cabinet
  • Regeneration by electricity, steam or gas

This range of dehumidifiers has a variety of applications, among others :

  • Dry air storage in general: Humidity control in unheated storage buldings
  • Internal corrosion protection of machinery parts, bridges etc. with dry air
  • Cold stores and freezers: Reduction of ice on evaporators, at doors, on ceilings and on goods
  • Process and production rooms with low %RH in the pharmaceutical and the food industries
  • Water work buildings (including open top filters)
  • Ships, protection of cargo
  • Shipyard, at sandblasting and painting
  • Ice rinks



All Cotes humidity controls, DR10, DA20, DH24, DCC, can be used for the CRT dehumidifiers. The choice depends on the degree of accuracy needed and external user information. Together with the DCC controller the dehumidifier can be delivered with stepless capacity control preparing the dehumidifier for control signal 0-10V and 4-20 mA (accessory)
