Environmentally Friendly Cooling with R290

All of our laboratory freezers use the natural refrigerant R290 – a future-proof and particularly eco-friendly solution. R290 stands out for its excellent energy efficiency and extremely low Global Warming Potential (GWP). This makes it an ideal choice for sustainable cooling and ensures compliance with current and future environmental regulations. In addition, R290 offers outstanding cooling performance while keeping energy consumption low – making it perfectly suited for reliable and sustainable use in medical environments.

Key Benefits:

  • Natural refrigerant,
  • free of F-gases
  • Very low Global Warming Potential (GWP = 3)
  • High energy efficiency
  • Powerful and reliable cooling performance
  • Compliant with future environmental standards
