Product features

BS/BD COMPACT – R line is equipped with a heater – water or electric, built inside the unit. Thanks to this, the unit easily adapts to the target room and has smaller dimensions. The unquestionable advantage of the device is the application of a modern and safe, self-regulating electric heater based on PTC heaters, which facilitates maintenance of significantly lower temperature of the radiator, complete elimination of the risk of overheating the system and obtaining a large heat exchange surface. BS/BD Compact-R meets the premise of the EcoDesign 2018 directive. BS/BD COMPACT – R AHUs are equipped with a rotary heat recovery exchanger, which ensures energy recovery efficiency of up to 81%.

The BS/BD-COMPACT-R range consists of 7 sizes, but there are no restrictions on larger units. There is the option of a customised unit in terms of materials and air output. The BS/BD-COMPACT-R air handling units are self-supporting without aluminium profiles. The outer panels of the HVAC unit are made of aluzinc outer metal sheets and galvanised inner sheets, forming the cladding for a mineral wool core. The air handling units are equipped with stubs for connection to ducts. The 50 mm thick mineral wool core has a good thermal insulating and sound attenuating performance. All functional sections are placed in one casing which makes the unit compact and facilitates its transport, assembly and operation. The unit is supplied as a complete unit with automation and wiring. The device is made in the plug & play standard.
