WK-com F air handling units with flat construction

High performance, compact design

WK-com F air handling units with flat construction

Always the right decision!

WOLF WK-com F compact flat units are ideal for convenient and efficient ventilation of demanding applications. The compact designs of the energy-optimised modules are versatile and feature a high output range. Depending on customer requirements, maintenance is performed from below or from one side of the unit. All components are fully internally wired to the individually configurable WOLF C-max control unit and the terminal unit (if an on-site control unit is used), making these air handling units versatile and fully customisable for your application.

Control

Control

Combination of the WK-com flat units with the WOLF C-max control unit yields an intelligent system solution in which all components work together perfectly. Mounted fully wired on the air handling unit for quick and easy commissioning at the installation location.
Optionally without control unit, with internal wiring to externally mounted docking stations and terminal boxes.

Material variety

You decide on the material: zinc-plated, stainless steel, aluminium (AlMg3) or painted/coated to customer requirements. Even combinations, such as a stainless steel internal casing with a zinc-plated outer shell, can be implemented easily.
Unit mounting

Unit mounting

The unit fixing holes provided as standard enable simple and secure mounting on the ceiling. Access for inspection and maintenance is not impaired.
Hygiene

Hygiene

With their smooth inner surfaces, WK-com flat units ensure no breeding ground for micro-organisms. Their casing is sealed hygienically with tested, microbially inert sealants.

Noise transmission

To prevent noise transmission (of both structure-borne and acoustic noise), only insulating connectors (zinc-plated or stainless steel) are used. These can be completely isolated and insulated to prevent the formation of weak spots. Whisper-quiet: The acoustically optimised casing design with a sound-­absorbing coefficient Rw of 38 dB to DIN 52210 minimises noise emissions from the fans.
Unit connection

The externally mounted module connectors enable swift, secure and permanent unit installation.

    WK-com F air handling units with flat construction Modular Design

    Modular design

    Thanks to the modular, inherently stable framework construction, all arrangements and combinations are possible. The WOLF modular design allows a wealth of variations and solutions. You choose the side from which to operate. Whether you are looking for operation and maintenance from the side or below – every conceivable casing arrangement is feasible with WK flat units.

    Fans

    Fans

    The WK-com F uses energy saving EC fans. Apart from a high efficiency of IE4, they boast extremely quiet and low-vibration operation thanks to the optimised blade profile.
    The integrated electronics make frequency converters unnecessary and ensure demand-dependent, variable speed control.
    3D Condensate Pan

    3D Condensate Pan

    At high levels of heat recovery, condensate forms during cooling and humidification. This must be removed quickly and reliably. The WOLF 3D pan, made from aluminium or stainless steel, has a three-dimensional fall, which reliably prevents water residues and the associated hygiene risks from bacterial growth.
    Heat recovery

    Heat recovery

    High-grade counter-current plate heat exchangers with heat recovery coefficients up to 90 % recover valuable energy from the extract air. The wear-resistant systems impress with high operational reliability, relatively low costs of purchase and efficiency in operation. They are hygienically safe thanks to fully separated air flows. The standard integral bypass with control damper and servomotor enables optimum output control. The surroundings of the heat recovery system can also be used for free cooling (introduction of cool outdoor air for room cooling without any use of artificial cooling energy).
    Filters

    Filters

    All WK-com flat units are fitted with 48 or 96 mm thick panel filters as standard (M5-F9) to EN 779 (2012) or ePM 1 - ePM 10 to ISO 16890. Additional filters can optionally be fitted by adding filter sections, for example in the biostatic version. The filters treated with biostatic preservative prevent the growth of fungi and bacteria to ensure clean, healthy air. Biostatic filters boast an outstanding dust storage capacity and efficiency in damp conditions.

      options, combination and extension modules

      Fan module

      Various individually sized and optimised EC fans can be used for each unit size. With their integrated electronics, the fan/motor units allow continuously variable output control.


      The sizing takes account of all external and internal resistances and ensures that the optimum fan is always selected.

      Casing options

      The frame is available in zinc-plated and stainless steel 1.4301 versions, whilst the cladding panels can be supplied zinc-plated, in aluminium AlMg3, stainless steel 1.4301 or with a RAL paint finish according to customer specification.
