We are ready for CO₂

Welcome to the future of refrigeration: technology: carbon dioxide R744 (CO₂) as an alternative refrigerant.

Explore a future that focuses on environmental protection, energy efficiency and sustainability. As R744 is a new refrigerant for many, it is also important for us to be well informed on the subject and the differences to other conventional refrigerants. As a competent wholesaler, we strive to support you, clarify questions and do everything we can to ensure that your projects can be implemented safely and flawlessly in the future.   

Here you can find out everything you need to know about CO₂ refrigerant, from its benefits to its applications.  

Why CO₂?

The refrigerant R744 is not only an innovative choice, but also a sustainable solution for refrigeration and air conditioning systems. It offers many advantages:

  • Environmentally friendly CO₂ is a natural refrigerant that has no negative impact on the ozone layer and has a low greenhouse effect. The use of CO₂ as a refrigerant actively contributes to environmental protection.
  • Energy efficiency CO₂ is extremely efficient and enables significant energy savings. This leads to lower operating costs and an improved environmental footprint.
  • Versatility CO₂ is used in a wide range of installations, from food refrigeration to air conditioning. The adaptability of this refrigerant makes it the ideal choice for various industries.
