Legal Restrictions

As no restrictions or bans are expected due to the F-Gas Regulation, propane is considered highly price-stable and future-oriented. By utilizing the low greenhouse effect of the refrigerant and its good compatibility with nature, you bypass any refrigerant regulations and can expect long-term operation with low maintenance costs.

Applications

The system can be used in industrial, process, and commercial facilities. The components are designed for permanent outdoor installation and suitable for long-term operation. With a flexible configuration, the propane refrigeration machine can be tailored to the customer's needs.
