Energy-saving ventilation system TwinFresh Comfo series RA1-25, RA1-35, RA1-50
The ventilation system is designed for controlled air exchange in apartments, family houses, hotels, cafes, etc. The system is equipped with a ceramic heat accumulator for fresh air heating by means of exhaust air thermal energy.
The ventilation unit is designed for installation in external walls of buildings.
Many advantages at a glance
- Selectable versions: RA1-25, RA1-35, RA1-50
- 100 - 230 Volt, 50 / 60 Hertz
- efficient individual room ventilation (fresh air supply, exhaust air removal for rooms up to 50m²)
- Air purification of dust, viruses and bacteria
- Prevention of high humidity and mould formation
- Heat recovery and humidity compensation in the room
- Reduction of heating and air conditioning costs
- High-tech ceramic heat accumulators with the efficiency of energy recovery up to 90%
- reversing energy-saving fan (axial fan) with EC motor (direct current) with low energy consumption of 2.8 to 6.1 W and low voltage 12 V
- Quiet operation (13-33 dBA)
- Conveying air temperature (°C): -20 to +50
- easy mounting (for different wall thicknesses) and maintenance
- Filters with the overall class G3 ensure air purification
- decorative front grille made of ABS plastic (white)
- including mounting plate
- ergonomically optimized outer hood made of light- and weather-resistant plastic (white)
- built-in louver dampers with a thermal actuator
- designed for continuous operation
- no condensate deposits (the condensate is drained off on the building wall through the outer hood and the penetration of water is prevented)
- Setting option: 3 speed levels
- Control: including remote control, manually operated operating switches on the housing
- Delivery including plug
- Humidity control: setting of 45% / 55 % / 65%
- in larger rooms (over 25 m²) several ventilation systems can be installed (the control signal from the remote control is received only by the first ventilation system and the other ventilation systems are controlled only by the first ventilation system)
- the integrated control system enables speed control and setting of the operating modes
- Protection class: IP24
- suitable for extension, renovation and new construction of individual rooms in residential areas, houses, social and commercial buildings

Operating modes
The ventilation system has two operating modes:
- supply air / exhaust air (reversible, the ventilation system works in either supply or exhaust air mode)
- Regeneration (the ventilation system works in reverse operation with heat and moisture recovery)
The cycles of the ventilation system
Cycle I: warm air is extracted from the room. The exhaust air heats and humidifies the heat accumulator (up to 90% heat energy is transferred)
Cycle II: fresh outside air flows over the heat accumulator, takes out the stored heat and humidity until the room temperature is reached.
The cycles alternate after 70 seconds.
