Description
USE   
  • Arrangement of supply and exhaust ventilation with heat recovery in wet rooms like kitchens, bathrooms, utility rooms.
  • Balanced ventilation due to synchronous supply and exhaust ventilation.
  • Protection from outdoor noise.
  • Reducing heat losses caused by ventilation due to heat recovery.
  • Humidity control by means of the built-in humidity sensor.
DESIGN

Easy maintenance. Indoor unit is opened by a light
press on the latches on both sides.

One of the best regeneration efficiency on the market
due to innovative hexagonal structure of the heat exchanger cells.
 UNIT OPERATING LOGIC IN WINTER PERIOD  
 Phase 1 (70 seconds)   Phase 2 (70 seconds) 
  • One fan supplies fresh and cold air from outdoor, which flows through the correspondent part of the ceramic regenerator and absorbs accumulated heat and moisture.
  • Another fan synchronously extracts polluted and warm indoor air, indoor air, that flows through the other part of the ceramic regenerator and transfers heat and moisture to it.
  • After 70 second of operation, the fans change their rotation direction to the opposite and the cycle starts again.
 
CONTROL    
  • Operation mode is controlled with the sensor control panel located on the unit casing or the remote control.
  • TwinFresh Expert Duo can operate either as independent units, or can be wired with other ventilators in a house to be controlled with a master unit. In this case, only a master unit responds to a signal from the remote control.
  • TwinFresh Expert Duo is equipped with a humidity sensor for indoor humidity control. If indoor humidity exceeds a set point, the ventilator boosts to the high speed indepe dently on other interconnected ventilators in the system.
CONTROL EXAMPLE  
MOUNTING
  • The unit is designed for through-the-wall installation inside a prepared hole in an outer wall of the building. TwinFresh Expert Duo must be installed in each wet room (kitchen, bathroom, etc.) to be ventilated, while TwinFresh Expert should be installed in each living room to be ventilated.
