  • Energy is recovered due to reversing operation of the ventilator, which consists of two cycles:
  • CYCLE I. Warm stale air is extracted from the room, then it passes through the ceramic energy accumulator and while flowing through it, heats and moistens the ceramic accumulator transferring up to 88 % of its thermal energy. In 70 seconds, as the ceramic heat exchanger gets heated, the ventilator switches to supply mode automatically.
  • CYCLE II. Clean fresh air from outside passes through the ceramic energy accumulator, absorbs moisture and is heated up to the room temperature due to the accumulated heat. In 70 seconds, as temperature of the accumulator drops down, the fan switches to extract mode and the cycle is renewed.
  • The ventilator changes its operation mode between supply and extract ventilation every 70 seconds.
TWINFRESH COMFO CONTROL AND OPERATION MODES
  • The TwinFresh Comfo series ventilators are equipped with a remote control.
  • If several ventilators are integrated into a central remote controlled ventilation network the signal from the remote control is received by the first ventilator only.

VENTILATION SYSTEM ARRANGEMENT EXAMPLE BASED ON TWINFRESH VENTILATORS
  • To arrange a ventilation system based on TwinFresh ventilators, install one ventilator in each room.
  • For larger premises, install two or more ventilators.
  • It is advisable to use paired units to ensure balanced ventilation.
  • While integrating many ventilators into a single network one part of them must be set into air supply mode and the other part must be set into air extract mode.
  • TwinFresh ventilators are also suitable for use as single units.
  • Operation mode of each ventilator installed in a separate room is individually adjustable.
  

  • Air flows from one room to another through door grilles, openings or halls and provides that way required circulation in a premise.
  • An energy regeneration ventilation system based on the TwinFresh ventilators is designed to save operating costs for heating and air conditioning.
  • To arrange the most energy efficient ventilation in a kitchen or in a bathroom we recommend to install in the kitchen or in the bathroom the intelligent VENTS iFansthat extract air on a signal from the activated motion or humidity sensor.

  • The TwinFresh Comfo RB1-50 unit is equipped with a decorative front panel internally lined up with an insulation layer for extra sound attenuation and condensation prevention.

 

  • Air filters.
  • Two built-in filters with total filter class G3 are used to clean supply and extract air flows.
  • The filters ensure fresh air cleaning of dust and insects and prevent the ventilator parts from soiling.
  • The filters have antibacterial treatment.
  • The filters are cleaned either with a vacuum cleaner or flushed with water with no harm to the antibacterial treatment.
  • F8 filter is available as an option.

 
  • Ceramic energy accumulator (regenerator).

  • The high-tech ceramic energy accumulator with regeneration efficiency up to 88 % is used for extract air heat energy recovery and supply air heating.
  • Due to its cellular structure, the unique energy accumulator has larger air contact area and excellent heat conducting and accumulating properties.
  • The ceramic energy accumulator has a special anti-bacterial treatment to prevent bacteria generation inside of the regenerator.
  • The antibacterial treatment is rated for 10 years operation.
  • The outer side of the regenerator is lined up with a heat insulating material.

 

  • Reversible DC fan.
  • Air is supplied or extracted by a reversible axial fan with DC motor with safe voltage 12 V.
  • Due to DC technology the fan is distinguished with low energy demand.
  • The motor has overheating protection and ball bearings for longer service life.

 

  • Outer ventilation hood.
  • The specially designed outer hood enables removal of extract air flow and condensate that is generated inside of the outer hood from the building wall.
  • Besides, the outer hood prevents ingress of water and foreign objects in the ventilator.
  • The outer hood is internally covered with insulating material that absorbs street noise penetration into the room through the ventilator and prevents condensate generation in the outer hood.
  • The EH 150 outer hood is made of polymer coated aluminium.
  • The EH-2 150 outer hood for thin walls is made of polymer coated stainless steel.
  • Due to its labyrinth structure of the outer hood air flow changes its direction several times and the ventilator is protected against direct wind impact.

 

  • Mounting plate
  • The TwinFresh Comfo series models are equipped with a mounting plate which facilitates servicing of the fans, filters and the regenerator.
  • The ventilation unit is fixed to the mounting plate with special magnets and contact sockets.
  • The ventilator inner parts are accessible by pulling the ventilation unit by hand.

 

  • Telescopic air duct.
  • Round air ducts are made of PVC plastic.
  • The telescope length is adjustable to the wall thickness which makes mounting quick and easy.
