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.

Software for a perfect plant analysis

Our AC-Systems contain a specially developed compressor module, integrating the whole electronic periphery of the compressor.

The module is monitoring the essential parameters: motor and compressed gas temperatures, oil supply and application limits.

The corresponding software can track all operating data tracked during operation. These data are recorded, enabling an ideal analysis for plant operation.

SMARTCOOL by WOLF:
Adiabatic evaporation cooling for a minimized energy consumption.
Together with our highly efficient heat recovery systems, the required refrigeration capacity can be reduced considerably in summer, decreasing significantly the energy consumption of an air handling unit.

WOLF: 100% CUSTOM-FIT

Different combinations of direct refrigeration enable a suitable solution for each application.

Use the full potential!

  • Heat pump function
  • Usage of the “free” condenser heat for reheating in dehumidification operation
  • “Free” condenser heat for warm water heating or as process heat
  • “Smartcool” combination with heat recovery
