WOLF Easy Lifting System

Difficult site conditions for engineers and installers? WOLF has the answer: the Easy Lifting System. It simplifies and speeds up transporting functional units to or into a building and improves the installation process. It is so effective that it can be used to transport even our largest AHU components, such as thermal wheel or plate heat exchangers, into any building or onto any roof without any trouble.

The Easy Lifting System also greatly improves the hygiene of WOLF AHU appliances. The sophisticated connection and transportation technology virtually eliminates any leakage from heat exchangers or unit cubes.

  • The advantages of the Easy Lifting System

    • Easy transportation and simple installation
    • Saves a huge amount of time and reduces the potential for error
    • Lifting eyes for straightforward transportation by crane or helicopter
    • No balance problems: lifted from above instead of from below (using rods, rails etc.) 
    • Cube joiners for quick assembly and lowest air leakage class L1 in line with DIN EN 1886 
    • Significantly improves appliance hygiene
    • Optimises the construction of large components such as thermal wheel or plate heat exchangers

     

    Our tip: If you are rather dubious about splitting assemblies, we would be happy to deliver all our appliances fully fitted on a base frame — and even fully wired on request.

Highest hygiene standards

Air is treated like food in our air handling units (AHUs). With well thought-out technical solutions and an optimal unit design, our claim goes beyond the fulfillment of hygienic standards.

Coupled with proper operation and regular maintenance according to VDI 6022, WOLF ensures hygienic air exchange in buildings.

02. WOLF SuperSeal

Closer to the limit

The WOLF SuperSeal sealing system achieves unprecedented air-tightness in all critical areas of an air handling unit, starting with the labyrinth sealing system that can boast 98% air-tightness (in line with VDI 3803/5). It eliminates the need to allow for additional volumes of intake and extract air, as was necessary in earlier fan designs.

    Redefining standards

    Additional output and increased power consumption for intake and exhaust fans are also a thing of the past thanks to the WOLF SuperSeal. In combination with an F7 carbon filter in the intake and extract air, unpleasant odours can finally be banished to where they belong: the extract air.

    And it doesn’t stop there — the doors feature an extra wide, double-lip cascade seal. In combination with our distinctive red seal profiles, we achieve class L1 air-tightness (in line with DIN EN 1886) as standard. 

    The WOLF SuperSeal system guarantees the highest hygiene standards in AHU appliances. It prevents the ingress of dirt particles through joints in the appliance. It also minimises the volume of potentially contaminated recirculated air in the heat recovery system – a critical factor with regard to viruses.

     

    Overview of benefits: 

    • Minimises the volume of recirculated air in heat recovery systems
    • Fitted as standard on all WOLF air handling units 
    • Airtight housing for outstanding hygiene: no intake of contaminants from the surrounding air 
    • No air bypasses the filter or heat exchanger, no ingress of ambient air into the appliance

    03. Get the perfect look

    Custom RAL colours

    Whether an AHU appliance is installed inside or outside a building or even on a roof, it is vital that the appliance does not clash with the architecture. Ideally, the building and domestic technology should blend together seamlessly. This also looks good on satellite images. The modular and compact air handling units can be finished in any RAL colour you desire. Naturally, they are also available with durable C5 paintwork capable of withstanding extreme environmental influences.

    04. Complete wiring systems for all switch cabinets

    Directly from the WOLF factory

    We provide complete wiring services not only for compact appliances, but also for all other WOLF appliances, We strongly recommend these services to anybody involved in a construction project. The times of homespun wiring, often installed unprofessionally on site in difficult circumstances, are gone. Our industrial standards enable us to route all electrical wiring perfectly and flawlessly without damage the housing. We can also prevent the ingress of moisture using innovative solutions – particularly important for outdoor installations. A terminal strip is also applied to create a tidy interface between the various components – the best results can only be achieved by using WOLF control units.

    WOLF KLM-L wired

    Tidy and precise

    For example, we work with great dedication to find the perfect probe position. Only then can the high-quality components work with maximum efficiency.

    Probes and sensors installed on site are usually not positioned at the ideal location. This can impair their efficiency or even cause malfunctions. The air handling unit of the future is pre-wired, has an integrated control unit and is delivered to the construction site in one piece – and is preferably Made by WOLF, of course.

    05. Certified and safe

    We are committed to quality

     

    At WOLF we consistently and verifiably implement all structural, energetic and hygienic requirements, regulations and mandatory specifications. Strict adherence to standards regarding the wide variety of quality directives is the fundamental basis for proficient system planning and efficient operation. We are intensively involved in specialist committees, quality associations, organisations and institutions to help us fulfil new standards as early as possible. This is how we accommodate the growing hygiene and energy awareness of designers, developers and operators and respond proactively to topics such as energy-aware construction (green building), sick building syndrome (SBS) and the professionalisation of holistic building expense management (lifecycle costs).
