Adsorption dehumidifiers with air-cooled condensera L4 HPW

Ideal for emergency response

L4 HPW is a robust and compact dehumidifier for professional use. The principle for the drying occurs through adsorption but unlike an adsorption dehumidifier, water is being removed by condensation and pumped out and therefore no wet air needs to be evacuated. L4 HPW is also equipped with wheels and a foldable handle for best user-friendliness.


Benefits with L4 HPW:

  • Water is being removed by condensation – no need to evacuate wet air.
  • Ideal for pressure drying, especially negative pressure.
  • Suitable also in lower temperatures.
  • Energy that is consumed during the condensation process will bring additional heat to the room or can be targeted to dry the damp material.
  • Equipped with wheels and foldable handle.
