Heat Recovery Unit

WAFE 1000 E/EFS is a decentralised ventilation unit with a enthalpic heat recovery, designated for areas with extended number of persons: commercial and public properties, light industry. It is the first heat recovery unit with this cubic capacity completely cast from expanded polypropylene. This unit is definitely the lightest one in its category. It is endowed with an integrated sound silencer and provides modular positioning for 360° installation. Remote wireless controlling is possible by connecting the unit to Sigox IOT network


  • Enthalpy: the unit does not require condensate drain and only limited or no use of preheating.

  • Control and monitoring: Apart from the standard WIFI or ethernet connection, Sigfox IOT network connection may be used.

  • Universal positioning that enables maximal utilization of space: The unit can be placed on the wall or on the ceiling - especially useful for reconstructions.

  • Light weight: The first recuperator in its category made of expanded polypropylene so 75 kg weight allows easy manipulation and installation.

  • Innovative technology: natural humidity is maintained with WAFE enthalpy flap system of an enthalpic heat exchanger.

  • Low operating costs: Prolonged filter lifetime, low electricity consumption, high heat exchanger efficiency

  • Invisible, inaudible: Experienced project architect can design an individual placement and sheathing to let the unit merge with the room.

Application and Use

Simplicity of installation and variability of positioning opens the door to easy and high-quality ventilating solutions that have not been previously possible.

Optimization of the output determined by an intelligent control reduce the overall energy consumption. The unit simply ventilates more when people are present. The ventilation decreases its power to a minimum level automatically when the room is empty. The difference between WAFE units and the others lies in the long-term operating costs. The EFS unit uses standard high efficiency heat exchangers with easy maintenance. Thanks to this it will not degrade over time like units with celulose membrane heat exchangers. The E version of WAFE 1000 uses the latest enthalpic membrane exchangers made of washable materials reducing the degradability to minimum as well.  The connection via IOT Sigfox Network or ethernet cable provides monitoring, simplifies maintenance and remote control.
