This enthalpy exchanger is dimensionally identical to the recuperators in the recuperation units Stiebel-Eltron LWZ 604-5-8, 303, 304, 403, 404, 504 and is normally installed in the units.

However, it is not an original spare part supplied and fitted by the manufacturer of the unit, so its use is at the discretion of the user of the recuperation unit.

  • The new generation of enthalpy counter-flow heat exchangers is an ideal alternative to standard heat exchangers. In residential premises with low humidity they are ideal for maintaining a comfortable microclimate by recovering humidity from the extract air.

  • This process is possible due to the unique polymer membrane with a microporous structure that enables transition of water vapour molecules, but blocks transition of bacteria, germs, mould, gases and smells. This design enables to keep high hygienic standards also in sanitary areas, kitchen and laboratories and other premises with permanent sources of air pollution. No transition of smells and toxins. Only warmth and water vapours are allowed.

  • The supply and extract air streams are moved in the air channels of the heat exchanger plates toward each other. The sensible and latent heat energy is transferred thought the heat exchanger membrane.
  • The comparison of the standard plate heat exchangers  and the enthalpy heat exchanger shows that the standard heat exchangers have higher sensible heat recovery efficiency as compared to the enthalpy heat exchangers, but the enthalpy heat exchangers of this series have higher total heat recovery efficiency due to the latent heat recovery from water vapour.

  • The heat accumulating mass consists of special plates laid as channels to enable moving of air streams toward each other.
  • The ultrathin membrane is used as a barrier in the heat exchanger.
  • The rigid airtight casing is protected against mechanical influence.

  • The membrane is a polymer material with a high coefficient of thermal conductivity and moisture transfer. The membrane enables transition of water vapour but blocks transition of biological contaminants, viruses, gases and foreign smells.
  • The membrane has a special coating that is resistant to acids, alkalis and salts. This coating is necessary to ensure stable operation during membrane application.
  • The membrane is both tear-resistant and puncture-resistant.
  • The membrane has excellent resistance to environmental influences and temperature drops from
    -25 °C to + 50 °C.
  • The membrane ensures low air leakage (<1%).
  • The membrane protects the premises from the penetration of the SARS-CoV-2 virus, bacteria, mould spores, gases (CO2/SF6) and various smells due to its structure. The membrane blocks the penetration of particles >30 nm in diameter. For reference: the diameter of the SARS-CoV-2 virus ranges from 60 nm to 140 nm.

Enthalpy exchanger - membrane

  • Central ventilation
  • Single-room ventilation
  • Heat recovery with air humidification in winter
  • Cool recovery with air dehumidification in summer
  • School premises
  • Health care buildings
  • Office buildings

  • Air sealing process is automated.
  • High-quality hot-melt synthetic-base polymer adhesive used in food and pharmacy industries provides air tightness.

  • The applied materials enable operation, storage and transportation of the heat exchangers in the temperature conditions from -25 up to +50 °C.
  • Storage of heat exchangers in an exposed position in direct sunlight is forbidden.
  • The enthalpy heat exchangers are not subjected to freezing in case of normal operation conditions in winter.

  • Regular check-up of filters is required to keep the heat exchangers and the supply filter clean. The filters must be cleaned or replaced as
  • To remove the contaminations flush the heat exchanger with warm water up to 30 °C.
  • Do not use high pressure water jet for cleaning of the heat exchanger because it may damage the ultrathin membrane.
