Significant energy savings. Up to 80% energy cost savings by free-cooling mode, reducing the load on compressors.
RW / EFC ax Chiller with Free-Cooling
energy saving and performance optimizationThe RW / EFC ax chiller combines energy efficiency and sustainability for industrial refrigeration with integrated free-cooling technology. The combination of operating modes, between free-cooling and compressor operation, allows up to 80 percent energy savings compared to conventional versions.
Efficient at very low temperatures. The lower the outdoor air temperature, the higher the efficiency of the machinery: with a temperature difference greater than 5°C, free-cooling operation is able to completely shut down the compressors.
Customizable and integrable configuration. Turnkey solution that integrates with other systems and components: a single point of contact for the entire refrigeration system.
Optimized resource management. Brushless EC fans ensure precise control, reduced compressor operating hours, and reduced energy consumption as a result.
Durability of the system. Less use of compressors ensures an increase in the lifetime of the entire system.
Remote monitoring arranged. Different types of IoT services are available.
Chiller with Free-Cooling: description and operation
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.
