The NRB Free Cooling (glycol-free) models are chillers that are designed and built to meet air conditioning needs in residential / commercial complexes, or cooling needs in industrial complexes where the use of glycol is not permitted. They are outdoor units with scroll compressors, axial fans, external copper coils with aluminium fins, and a plate heat exchanger. Fitted with a free cooling coil, they are used when the cooling request continues into the winter months, or in any case when the outdoor air temperature is lower than the temperature of the return liquid in the system. In Free Cooling mode (Free Cooling Plus compressors, or just Free Cooling), the fluid is cooled directly by the external air to the point that the compressors can be completely deactivated, thereby ensuring notable electricity savings.
