The RW / EFC ax chiller from Frigofluid, a partner company of MITA Cooling Technologies in MITA Group, is designed to provide efficient industrial cooling through a combination of operating modes.
In fact, the structure of the system allows it to automatically manage three operating modes depending on the season and ambient air temperature:

• Summer mode. With outdoor temperatures above 23°C, the chiller uses only the compressors to maintain fluid temperature, ensuring maximum cooling performance even during the hottest periods.
• Intermediate mode (partial energy saving). When the ambient air varies between 15°C and 23°C, the system combines the action of the compressors and the free-cooling section. This provides partial energy savings by using the cooler air to reduce the compressor load.
• Winter mode (total energy saving). At temperatures below 15°C, the chiller relies solely on the free-cooling section. Cool outside air is used to cool the fluid without compressor operation, ensuring low energy consumption operation.

This technology, which integrates the operation of a chiller with that of a dry cooler, exploits free-cooling separately from the refrigeration circuit, improving operating efficiency and extending component life.

This advanced configuration makes the RW / EFC ax chiller a sustainable and cost-effective solution for industrial cooling needs, reducing environmental impact and improving the energy efficiency of the entire plant.
