Unit description Water source reversible unit with total heat recovery for the simultaneous production of chilled/hot water with hermetic rotary Scroll compressors, with R410A, plate heat exchangers and thermostatic expansion valve. The range is composed by units equipped with two and four compressors, all with two refrigerant circuits. Version B - Basic Features REFRIGERANT GAS R410A The use of R410A allowed to achive better energy efficiencies with environment full respect (ODP = 0) INTEGRATED CONDENSATION´S CONTROL A 2 way valve is supplied as standard for the condensing pressure control. For all the applications in which a constant waterflow through the condenser is needed, a 3-way valve option is also available under request. ENERGY SAVING Energy saving guaranteed by the advanced operation’s logic. The best operation mode is set completely automatically and independently by the unit’s controller, in order to minimize the absorbed energy whatever the cooling and/or heating demand might be HOT WATER SUPPLY Production of domestic hot water up to 55°C in both summer and winter operating conditions, offering maximum versatility with respect to different plant engineering solutions.
