Unit description Outdoor unit for the production of chilled water with hermetic rotary Scroll compressors, ozone-friendly refrigerant R410A, axial-flow fans, shell and tubes exchanger and electronic expansion valve. The range is composed by units equipped with four, six and eight compressors in multi-circuit configuration. Version B - Basic SL - super-low noise version CA - Class A of efficiency SL-CA - Super Low noise version, Class A of efficiency Configurations - - basic function D - partial condensing heat recovery function R - total condensing heat recovery function Features REFRIGERANT GAS R410A The use of R410A allowed to achive better energy efficiencies with environment full respect (ODP = 0) ALUMINIUM MICRO-CHANNEL HEAT EXCHANGERS This new range of chiller uses aluminum micro-channel condensers that ensure a premium level of efficiency. This solution also allows to reduce the refrigerant charge with respect to traditional copper/aluminum coils, assuring the minimum allowable ratio between the refrigerant volume and the power capacity thus making this product range unique in the market, also improving the resistance against corrosion in saline or corrosive atmospheres.
