State-of-the-art AHU

The series only uses the latest generations of each fan and heat recovery system, like highly efficient thermal wheel heat exchangers (TWHE) with temperature and humidity transfer levels of over 90% and unprecedented tightness rates of 98% to VDI 3803/5. WOLF also always complies with all relevant standards and regulations. Heat generators and cooling sources can be integrated into the appliance if required. A heat recovery system, integrated heating appliance and a variable speed refrigerating unit and heat pump make the WOLF KG Top an all-in-one energy centre.

KG Top heat recovery

Highly efficient thermal wheel heat exchanger
Flexible heat recovery with a compact footprint
Thermal wheel heat exchangers function as regenerative heat recovery systems (WRG). They are suitable for use across the entire air flow rate range. With the benefit of their compact design and ability to transfer high heat recovery outputs, they are especially effective in higher air flow rate ranges. The AHU achieves temperature and humidity transfer levels of over 90% and unprecedented casing tightness rates of 98% according to VDI 3803/5.

High-performance run-around coil system
Highly efficient heat recovery throughout the entire system.
Highly efficient heat recovery, even in areas with particularly stringent indoor air quality requirements. Complete separation of the supply and extract air flows means that no pollutants, moisture, odours or bacteria can be transferred from one to the other.

- What does Easy Lifting mean?
  Difficult site conditions for engineers and installers? WOLF offers just the right answer: the Easy Lifting System. It makes transport onto or into a building much easier, and the installation of these functional units becomes quicker and more accurate. It’s so simple that even our largest components, such as thermal wheel or plate heat exchangers, can be easily brought into any building or positioned on the roof.
  
  The Easy Lifting system also makes a great contribution to the hygiene of WOLF AHU appliances. The intelligent connection and transportation technology virtually eliminates the risk of leakages in heat exchangers or appliance modules caused by installation errors.

- Delivery times?
  Our unique synergy of software and products is unrivalled in the industry.
  It makes our appliance configurations highly adaptable, our production methods efficient
  and also keeps our delivery times remarkably short.
- Do air handling and ventilation systems encourage the spread of viruses?
  There is currently no evidence to suggest that COVID-19 can be spread through air handling and ventilation systems. Indeed, experts agree that good ventilation of indoor areas helps to keep the risk of infection down. In addition to systems being technically up to date and planned and installed correctly, they must also be operated properly and serviced regularly for operation to be safe and hygienic. If these points are carefully followed, air handling and ventilation systems pose no increased risk of infection according to the experts.
- What are the effects of filtration?
  When considering whether COVID-19 can be filtered out using ventilation system filters, the first point to bear in mind is the size of viruses. Viruses are significantly smaller than bacteria, which are relatively large at 1-10 µm and can therefore be separated out efficiently by ePM1 fine dust filters. The coronavirus measures approximately 0.16 µm. Having said that, viruses are generally attached to aerosols or dust particles. Transmission is primarily via droplets. Droplets that people produce are 0.5 to approx. 15µm in size. From other viruses it is known that a 1µm-droplet can contain a sufficient virus concentration to trigger an infection.
  ePM1 filters separate out particles and aerosols, i.e. including droplets, down to a size of 1µm, depending on the separation efficiency. With higher separation efficiency, more of these droplets are separated out and thus remain in the filter medium. When filters are replaced during servicing, personal protective equipment (PPE) should therefore always be worn. This is true irrespective of the current COVID-19 pandemic, as it is generally unknown what substances have been collected in the filter.
- What are the key points to remember regarding operation and maintenance?
  Recommendations for the operation of air handling and ventilation systems during the COVID-19 pandemic have been issued in a joint communication by the BTGA (Federal Industry Association for Technical Building Installations and Services), FGK (Association for Building and Indoor Air Quality) and AHU-Herstellerverband e.V. (AHU Manufacturers Association). Fundamentally, continued good ventilation of indoor spaces is recommended, including in the current situation. Relative room air humidity should be between 30 per cent and 65 per cent. Very dry air affects the sensitive mucous membranes in the upper airway and makes them more susceptible to viruses.
