Total Heat Exchange Element (PDF)


An total heat(temperature and humidity)exchange element with special thin paper membrane, that is made with our unique tissue papermaking technology.
By its characteristic of special thin paper membrane(Gas barrier, Moisture permeability, Thin membrane), exhaust air and supply air will not be mixed. It enable to collect the energy from return air(temperature and humidity) to supply air effectively.

■Comparison of our and conventional product

Our total heat exchange paper(0.04mm)
  • Since this is the thin paper membrane with moisture permeability, temperature and humidity exchange efficiency is high.
  • The fine structure will prevent to mix the exhaust air and supply air.
    (Dirty return air will not leak)
