What is “Polymer Sorbent” ?

It is an unprecedented moisture absorbing and desorbing material which consists of organic polymer. Its characteristic mechanism “sorption” provides extremely high performance of moisture absorption-desorption. It does not has deliquescence property and can be used repeatedly.

Polymer Sorbent Graph
  • It has high hygroscopic performance over a wide relative humidity range from low humidity to high humidity.
  • Its adsorption/desorption isotherm changes linearly over relative humidity.
  • Its hygroscopic capacity is two to three times as high as the capacity of silica gel. It has superior performance especially in high relative humidity range.
  • Compared with conventional hygroscopic materials, Polymer Sorbent is possible to regenerate at low temperature and it is possible to utilize low-temperature waste heat for regeneration source.
    1. Eks-rotor®・Eks-block®

    Polymer sorbent realizes energy saving, air conditioning, dehumidification / humidification, air quality improvement by making good use of excellent low temperature regeneration characteristics.

    1. HU granular moisture absorbing agent

    It is a granular polymer sorbent with particle size of several millimeters. It is possible to use it with simple equipment such as filling in a column

    1. Moisture permeable sheet , Total heat exchange element

    A moisture permeable sheet using Polymer Sorbent has high moisture permeability while suppressing the passage of air. Its excellent moisture permeability delivers the high performance for total enthalpy heat exchange system
