Unit description Outdoor unit for the production of chilled water with hermetic rotary Scroll compressors, ozone-friendly refrigerant R410A, axial-flow fans, braze-welded plate-type heat exchanger, micro-channel full-aluminum air coils and thermostatic expansion valve. The range is composed by units equipped with four compressors in tandem configuration on two independent refrigeration circuits. Version K - Standard efficiency, compact version LN-K - Key efficiency, compact and low-noise version SL-K - Key efficiency, compact and super low-noise version Configurations - - basic function D - partial condensing heat recovery function Features REFRIGERANT GAS R410A The use of R410A allowed to achive better energy efficiencies with environment full respect (ODP = 0) MAXIMUM COMPACTNESS This new range is available in the new K version, that integrates the maximum compactness with a qualifying unit’s efficiency. This allow to achieve a very high flexibility in the design process as well as during the on-site installation operations, offering a premium solution in case of reduced clearances or when retrofitting existing installations.
