BSK SCHOLAR-Clasroom Type Heat Recovery Device

1-Casing and Insulation

The casing of our devices is double-walled 0,7 mm galvanized sheets filled with 25 mm rock wool insulation material in order to keep keep the sound and heat insulation at the highest level. The outside as well as the inside surfaces of our devices are painted with electrostatic powder paint and deliver a long life, while providing a stylish and clean appearance.

2-Filters

Total of 3 filters are used in our devices to filter both the supply and exhaust air. M5 filter is used on the exhaust air to filter dust and protect the inside of the device.G4 and F7 filters are used on the fresh air side can stop particles up to 1 micron (0,001 mm) and filter allergens such as dust, spores and pollen that may come from outside. In addition, when the filters reach a certain filling rate, our devices give an automatic filter full warning, thanks to the differential pressure sensors that detect the pressure build up of filters.

3-CO₂ Sensor

Thanks to the carbon dioxide (CO₂) sensor on the exhaust air side, the CO₂ level of the environment can be continuously monitored and the device can automatically control the fans if it reaches a set value, which can be easily changed via the digital control panel.

4-Air and By-Pass Dampers

There are 3 dampers in our devices,2 of which is for blocking the outside air while the device is off and 1 for free-cooling. Thanks to the by-pass duct and damper, when the indoor and outdoor temperatures are close to each other, it is possible to by-pass the heat exchanger via the bypass channel to enter free cooling mode. This feature is activated automatically when the set temperature is reached

5-EC Fans

High efficiency EC fans are used in our devices. EC fans do not need frequency inverters like ordinary AC motors to be operated at the desired speeds, while consuming much less energy than their AC counterparts. Fans with reverse blade inclination on EC motors offer maximum performance thanks to the 3-dimensional blade curves, while minimizing the sound levels and providing a comfortable use.

6-Plate Heat Exchanger

High efficiency counter flow heat exchanger is the core of our units, where heat recovery takes place. Heat is transferred between exhaust air and fresh air, without mixing them, so it can supply 100% fresh air. Plastic plates are easy to wash and offer longevity. In exchangers operating with the counter flow heat transfer principle, thermal efficiencies of up to 95% between hot and cold air can be achieved.

7-Silencer

The silencer section at the fresh air outlet of our devices allows silent operation which provides a quiet working environment for classrooms or offices.
