The German Federal Ministry for the Environment provides support for development of sustainable refrigeration and air conditioning systems and equipment as part of the National Climate Initiative. The systems and equipment that receive funding subsidies do more than just use much less energy thanks to the use of high-efficiency components and systems. They also produce significantly lower CO2 emissions.

Ecofriendly alternatives? Yes, we use them!

  • Natural refrigerants are inexpensive, available in almost unlimited quantities and thus represent an environmentally friendly alternative to synthetic mixtures.
  • We have many years of experience working with natural refrigerants and rely on: Carbon Dioxide (R-744), Isobutane (R-600a) and Propane (R-290).
  • We are also one of the first to use low-GWP refrigerants of refrigerant class A1 according to DIN EN 3781-1.

Here’s how we reduce greenhouse gas emissions.

The EU is striving to reduce greenhouse gas emissions by 80 to 95 % compared to 1990 levels between now and 2050. The F-Gas Regulation is aimed at reducing emissions of these gases. We are among those making the switch to climate-friendly substitute refrigerants.

  • Regulation (EC) 1005/2009 on substances that deplete the ozone layer has banned the use of partially halogenated hydrofluorocarbons as virgin materials since 2010. This mainly affects the refrigerants R22 and mixtures with R22, such as R402A (HP80) and R401a (MP39), among others.
  • Taking into account the age, condition and remaining useful life of the refrigeration system, we recommend conversion to a drop-in refrigerant, partial conversion or new construction of the system - we will be happy to advise you on this.

  • Since 01.01.2020, the use of all unused refrigerants (virgin) with a GWP value* > 2,500 has been banned for placing new systems on the market and also for service and maintenance purposes.
  • Previously commonly used refrigerants, such as R404A (GWP 3922) and R507 (GWP 3985), also fall under the ban deadlines of the F-Gases Regulation (EU) 517/2014.
  • Operators of R404A systems should inform themselves in good time about converting their systems to a low-GWP refrigerant. We will inform you about alternatives and suitable concepts.
