AIR COOLED WATER CHILLERS WITH FREE COOLING u Solutions B - Base I - Integrated u Version ST - Standard u Equipment AS - Standard equipment DS - Desuperheater Cooling Capacity 44,9-409,8 kW Free-cooling Capacity 37,8-308,3 kW Housing Base made of painted galvanised steel; panels made of galvanised steel externally coated with plastic (PVC) film and mounted on aluminium profiles to ensure total weathering resistance. Compressor HERMETIC SCROLL type, complete with thermal protection. Antivibration mountings and oil charge are standard. Fan Low speed, axial-flow fans fitted with accident-prevention protective grille; directly coupled motor with built-in thermal cutout and IP 54 protection degree; aerodynamic housing and wing profile blades increase efficiency and decrease noise level. Air heat exchanger Finned coil made with copper pipes and aluminium fins offering a high exchange surface area. Water heat exchanger Plate-type made of AISI 316 steel complete with water differential pressure switch. Shell covered with closed-cell neoprene anti-condensate material. Electrical board Switchboard to standards IEC 204-1/EN60204-1, complete with con- tactor and protection for compressor and fans. Main isolator and door interlock safety device. Control The microprocessor controls the unit capacity by timing the compressors and checks the operating alarms with the possibility to connect to BMS. Refrigerant circuit Filter dryer, moisture-liquid sight glass, solenoid valve, intercepting valve on the liquid line, thermostatic expansion valve with external equaliser, HP and LP pressure switches, flooding coil and hot gas by pass pressure equalising valve.
