    BS air handling units use two technological solutions of the casing construction. The solution used so far is based on a frame made of aluminium poles and the solution based on a self-supporting structure. External casings are made of external aluzinc sheet, the internal is galvanised on both sides. Insulation is made of mineral wool with a standard insulation thickness of 50 mm (70 mm on special order). Selection between the two enclosure structural solutions depends on the rated air output, HVAC unit configuration, and air treatment specifications of each HVAC unit model.

    AHU tailored to your needs

    Sectional BS AHUs allow building any configuration of sections to achieve the specified air treatment through a wide selection of components per each AHU function. The concept behind the sectional AHUs is to enable a flexible selection of functional sections to meet the most demanding air treatment specifications. Flexible selection of functional sections in BS AHUs guarantees adaptation to individual investment needs and customer preferences.

    and Plug&Play

    For manufactured air-handling units, VBW Engineering delivers complete automation systems. VBW Engineering can also install, commission, and service the HVAC units with the aid of highly qualified and experienced service personnel. The HVAC unit control solutions are always adapted to the specific project requirements for the building and its users’ individual needs.

    The idea of the PLUG & PLAY automation system is to prepare the control system of the air handling unit so that it is ready for immediate operation.
    VBW Engineering offers air handling units together with a factory-fitted automation system. Internal wiring and switchgear with the controller mounted on the air handling unit.


    Advantages of using
    the PLUG & PLAY system

    Reduced installation and commissioning time
    (cost reduction)
    Commissioning without disturbances
    caused by difficult atmospheric conditions
    Electrical connections made and checked by
    qualified technicians
    electrical terminations, certified cable junction boxes and connections

    Gas-flow Heater

    Gas heating module

    Using the PEGAZ type heating module together with complete
    oil or gas installations is much cheaper than building a boiler
    room which is necessary to produce and send the heating
    medium to the central unit. PEGAZ heating modules with
    a gas or oil burner cooperate with BS sectional air handling
    units and air conditioning units, BD roof units and work
    as duct zone heaters.
