Applications
One system, many possibilities
- Building cooling & heating: Ideal for residential buildings, supermarkets, offices, restaurants, hotels, ice rinks, wellness facilities, greenhouses, and more.
Industrial & process cooling: Efficient for food processing, commercial cold storage, breweries, wineries, pharmaceuticals, or blast freezing.
Data centers & server cooling: Reliable performance to ensure maximum availability in digital infrastructures.
District heating & cooling networks: Perfect for neighborhoods, housing developments, or university campuses—with precise control and high return temperatures.
CO₂ is a safe choice for efficient and future-proof investments.
Its use depends on the supply temperatures and temperature differences of your project – and we’re happy to advise you!
