TwinFresh Solar SA-60 with a square 164x164 mm air duct TwinFresh Solar SA -60 Promit a square 164x164 mm air duct and a power storage tank TwinFresh construction The ventilation system consists of a controllable telescope. All TwinFresh and TwinFresh Comfo ventilation systems are equipped with multi-leaf dampers (models TwinFresh S-60 and TwinFresh SA-60) Ventilator does not run (blind dampers are CLOSED)Fan runs (blind dampers are OPEN)Models TwinFresh S1, SA1 and SA1 The unique regenerative heat accumulator has a cellular structure with a larger surface area and high efficiency. The heat accumulator is characterised by its excellent heat transfer properties and good heat storage capacity. the ceramic heat accumulator has a special antibacterial treatment to prevent bacterial proliferation. The antibacterial properties of the coating are designed for 10 years. The inside of the ceramic heat accumulator is lined with a thermal insulation material that also serves as a sealant. square air duct The square air ducts of the TwinFresh models are made of polymer-coated metal and are lined with an insulating fabric. The round ventilation pipes are made of PVC plastic. The telescope length is adjustable according to the wall thickness, which makes installation quick and easy. air filtersThe intake and exhaust air are cleaned by two built-in air filters with the entire filter class G3. The filters clean the supply air from dust and insects and prevent soiling of the ventilation system. The filters have an antibacterial coating Filter cleaning is carried out with a vacuum cleaner or with water, which does not remove the antibacterial solution. reversed EC fanA reversing axial fan with EC motor is used for ventilation and de-aeration. Thanks to EC technology, the fan excels with low energy consumption. The motors are supplied with extra-low voltage of 12 V. The motor is equipped with an integrated overheating protection and ball bearings for a long service life. mounting plate The TwinFresh Comfo models include a mounting plate which facilitates the maintenance of fans, filters and heat accumulators. The fan unit is fixed to the mounting plate with magnets and special interfaces. the inner part of the ventilation system can be reached after removing the fan unit, no special tools are required. The interfaces on the mounting plate allow several ventilation systems to be integrated into one ventilation system and enable synchronous operation. The TwinFresh Comfo RA1-25 model has no interface and these systems cannot be integrated into a ventilation network. outside hood Thanks to the special construction of the outside hood, the exhaust air flow and the condensate that forms inside the inside of the outside hood are separated from the building wall. In addition, the outer hood prevents direct penetration of water and foreign bodies into the ventilation system. The inner part of the outer hood is lined with an insulation layer to prevent condensation in the outer hood, while the outer hood is made of polymer-coated aluminium and the outer hood EH-2 is made of polymer-coated stainless steel. Thanks to the labyrinth structure of the outer hood, the air flow changes direction several times and thus protects the ventilation system against wind penetration into the air duct. power cord The TwinFresh Comfo ventilation systems are equipped with a power cord. The ventilation system is ready for operation and does not require any extra electrical connections. just plug the plug into the socket and enjoy the fresh air. If, in your case, the cables have to be flush-mounted and several ventilation systems have to be integrated into a network, you can remove the cable with the plug. operating logic of the TwinFresh ventilation systemsThe ventilation system can be operated in reversible operation with energy recovery or only in supply or exhaust air operation without the need for an external ventilation system. The warm exhaust air is extracted from the room via the ceramic heat accumulator. The exhaust air heats and humidifies the heat accumulator. In doing so, it transfers up to 90% of the heat energy to the building. After some time the heat accumulator heats up and the ventilation system switches to supply air mode. CYCLUS II The fresh, cold outside air flows through the heat accumulator and removes the stored heat and humidity from the heat accumulator until the room temperature is reached. When the heat accumulator is cooled down, the ventilation system switches back to exhaust air operation. The cycle restarts Switching to supply and return air operation takes place every 70 seconds.             TwinFresh Solar control and operating modes The system control allows four operating modes: Lü ventilation operation (delivery or supply air) at the 1 pace Ventilation operation (supply or exhaust air) at the 2nd speed Reverse operation (energy recovery) at 1 pace Reverse operation (energy recovery) at the 2 The TwinFresh Solar SA-60 ventilation systems are controlled by the KVS control unit and powered by the solar module. The scope of delivery of the TwinFresh Solar SA-60 Pro ventilation systems includes a power storage tank. During the day, the ventilation system is supplied by the solar module and the storage tank is charged. At night, the ventilation system is supplied by the power storage tank. an example of the ventilation system based on TwinFreshFor a ventilation system based on TwinFresh ventilation systems, install one ventilation system in each room. install two or more ventilation systems at night. The TwinFresh ventilation systems can be used individually or can be integrated into a ventilation system. If each ventilation system is operated separately, the operating mode of each individual ventilation system can be set individually. The TwinFresh Comfo models are fully operational and the TwinFresh Standard models still need to be connected to the control and power supply units. When connecting the ventilation systems, set up some ventilation systems in supply air operation and other ventilation systems in return air operation. We recommend installing the ventilation systems in pairs for controlled living space ventilation. in reverse operation with heat and moisture recovery, TwinFresh ventilation systems change their operating mode from supply air to exhaust air and vice versa every 70 seconds. In winter, the heat and humidity of the exhaust air is transferred to the heat storage tank and in summer the cooler is transferred. the air flows between rooms through openings and the corridor, thus creating air circulation in the house. Then the exhaust air is automatically withdrawn after the operation of the humidity or motion sensor.
