Description Air/Water chillers for outdoor installation, with Free-Cooling. Suitable for air conditioning of residential / commercial buildings and for the cooling of industrial buildings.
NRB free cooling and the outdoor chillers range with scroll compressors, axial flow fans, aluminium micro-channel coils and plate heat exchanger. The micro-channel coils make it possible to use a lower amount of refrigerant compared to the traditional copper/aluminium coils and ensure very high levels of efficiency. 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. Indeed, 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. The range is available in 4 versions also silenced, with increasing efficiency degree.The unit can work at full load with an outdoor temperature of up to 50 °C, depending on the size and version.
