Properties of the Compact Ventilation Units Type: SupraBox Comfort Hygiene Requirements The SupraBox Comfort Compact Ventilation Units conform to the current version the norm according to VDI 6022. The units have smooth surfaces (coil coated inside and out – RAL 7035) and are easily cleaned. Housing The units contain a sturdy frameless housing. The sidewalls have a double-layered design. The inside and outside metal sheets are made from 1 mm galvanized (coated) steel plate. The insulation thickness is 40 mm for ceiling units and 60mm for stand-alone units. Heat Recovery High efficiency counter flow heat exchangers with over 90% efficiency are utilized for heat recovery. Complete separation supply air and return air without odor transfer is ensured. Filter Fine dust filters of filter class F7 for supply air and class M5 (formerly F5) for return air are utilized for serial production. Quick release fasteners make changing filters fast and easy. Hot water Heater coil of the Construction Line SupraBox Comfort Pipe and Duct Connections The connections are designed for ample room. The connection sizes are the same as the industry standard sizes. EC-Fans EC-fans in compact design with modern EC-motors from inhouse production make for quiet and energy efficient operation across the entire product line. For temporary increased performance an optional boost-mode is available (upon request). Accessories (optional) For units from the SupraBox Comfort line an optional heating and cooling coil (hot water/cold water) for raising or lowering the room temperature is available. Furthermore additional electronic pre-/supplementary heating coils are offered. Hot water Heater coil of the Construction Line SupraBox Comfort Integrated Controller The SupraBox Compact Ventilation Units are equipped with an integrated controller as standard. All internal components are already pre-wired. Temperature control is possible with an optionally available heater/cooler. Many control functions are integrated into the software and can easily be subsequently activated. A control until for setting operating parameters is enclosed as standard.

Heat Recovery Efficiency of the Heat Recovery The SupraBox-Units are equipped with high efficiency cross counter flow plate heat exchangers made from corrosionresistant aluminum. The actual efficiency ratings that can be attained depend primarily on the operating conditions. Outdoor Air Temperature and Return Air Humidity During most times of the year the humidity of the return air is irreverent. If supply air and return air flow volumes are identical then the SupraBox attains efficiency ratings over 80%. With falling outdoor temperatures the surface temperature of the plate heat exchanger...

Heat Recovery Level of Return Air Volume in relation to Supply Air Volume 200% Ventilation heat loss The level of the return air volume in correlation to the supply air also has a strong influence on the efficiency of the heat recovery. If the return air volume is reduced compared to the supply air volume, then the efficiency rating of the heat recovery with regards to the supply air is also decreased. By looking at the resulting ventilation heat loss, an assessment is made possible of the higher return air in regards to the supply air. Since the entire air volume in the room to be...

Sound power level: The sound data represented in the air performance curve is the A-weighted apparent sound power level of the housing LWA2 in dB(A). Pressure side apparent sound power level Lwa5 = Lwa2 + 2 dB Discharge side apparent sound power level Lwa6 = Lwa2 + 20 dB Calculation: Lwa5 per octave: LwA5(Okt) = Lwa5 + correction value (table row LWA5) Lwa6 per octave: LwA6(Okt) = Lwa6 + correction value (table row LWA6)
