Future-proof design
The new EC-F-Gas Regulation (No. 517/2014) defines that manufacturers have to use refrigerants with a low GWP value (Global Warming Potential) in their units, contributing a lot to a reduction of CO2 emissions.

We at WOLF are using the climate-friendly R513A, so that you can operate your air handling unit with integrated cooling technology safely, maintenance-friendly and correctly even in the future.

The refrigerant R513A with a GWP of only 613,4 is able to reduce the potential CO2 emission to a third compared to conventional refrigerants such as R407C or R410A, contributing to a sustainable usage of modern refrigeration technology.

The new R513A is a mixture of refrigerants, consisting of 50 % of R134A and 50 % of R1234yf. By mixing the safety refrigerant R134a (A1) and the conditionally combustible refrigerant R1234yf (A2L), the refrigerant R513A (A1) is not combustible.

Competence from a single source
The refrigeration department at WOLF has decades of experience and expertise. Each customer request is processed individually in order to be able to offer the energetically and economically optimal solution.

Due to our flexible unit base, even special requests can be realized without any problems. From planning to final assembly, commissioning and on-site maintenance, you will work with certified refrigeration technology experts.

State-of-the-art technology, with its finger on the pulse. Our innovative strength from the interaction between people, technology and the company also gives you the security of being also ideally equipped in the future.

Ready for actionin flash
Integrating a refrigeration system into WOLF air handling units reduces the on-site installation and planning effort to a minimum.

Even at the planning stage, we take into account all pipe routing and the necessary installation conditions. The cumbersome coordination between many trades involved during the construction phase. In the end, everything fits perfectly and the system can be put into operation quickly, conveniently and uncomplicated.

WOLF Measuring and Regulating Technology

Two SOLUTIONS – one system
The extensive possibilities of our measuring and regulating technology offer the right solution for each plant. The pre-configured WOLF C-MAX compact presents a compact and cost-optimized unit. For individual requirements, we provide WOLF C-MAX flex program, fulfilling any requests of a ventilation regulation.

Plant-specific ex Works
From compact ceiling unit to roof central with refrigeration and humidification control. For customer-friendly commissioning, WOLF C-MAX is already configured ex works specifically for each plant. For commissioning only the nominal values, fixed speeds, volume flow, pressure and switching times have to be adjusted individually by customer.

Easy and Comfortable Handling
All important settings can be adjusted comfortably on the clearly legible control unit. Choose kind of operation, temperature or requested operating time. On the optional touch control unit, the plant functions can also be monitored as a graphic scheme.

Energy-efficiently matched
WOLF measuring and regulating technology is the ideal solution to secure a specific customer-tailored plant function in a perfect symbiosis between energy efficiency and performance.

Comprehensive Language Setting
A total of 13 languages enable the use of WOLF regulation almost everywhere: German, English, Danish, Dutch, Finnish, French, Italian, Lithuanian, Polish, Russian, Spanish, Swedish, Turkish.

Longstanding Partners
The market offers innumerable solutions, more or less convincing. For hard- and software, we rely on sophisticated regulation technology by Siemens.
