Refrigerant: 134a or R22EKSC series screw-type water cooled chillers feature a leading-edge screw unit design, inherit this air conditioning innovations over 40 years and integrate 13 patents. Equipped with a double screw compressor and a high-efficiency heat exchanger developed by us, the units work at the optimal efficiency with the help of a state-of-the-art control system. Thanks to an innovative condensate heat recovery technology, the units can be used for multiple purposes to save energy, and best apply to places that have mangy buildings and require central air conditioning and hot water systems, such as high-rank hotels, office buildings, schools, hospitals and factories.Screw type water cooled chillersModel No.EKSC250EKSC280EKSC330EKSC400EKSC450EKSC500EKSC560EKSC660EKSC800EKSC900CoolingCooling CapacityU.S.RT248.5280.6331.8403.5448.8496.9561.3663.5806.9897.6KW873.89871166.914191578.41747.619742333.72837.93156.8Power InputKW153.3170.6200.6244.5271.5306.5341.2401.2489543COPkw/kw5.75.795.825.85.815.75.795.825.85.81Chilled water flowm³/h150.3169.8200.7244.1271.5300.6339.5401.4488.1543Pressure drop of chilled waterkPa42424955576267697272Cooling Water flowm³/h176.7199.1235.2286.1318.2353.3398.2470.4572.2636.4Pressure drop of cooling waterkPa47475967778282828585HeatingHeating CapacityU.S.RT347.8392.3462.4562.4625.4695.6784.5924.91124.91250.7KW1223.21379.61626.41978.12199.42446.42759.23252.83956.24398.8Power InputKW197.1220.1259.2315.3350.6394.2440.2518.4630.6701.2COPkw/kw6.216.276.276.276.276.216.276.276.276.27Hot water flow ratem³/h150.3169.5199.8243270.2300.6339399.6486540.4Pressure drop of Hot waterkPa34344348565959596161Water source flow ratem³/h176.5199.4235.2286318353398.9470.3572636Pressure drop of water sourcekPa58586776788287899090CompressorTypeSemi-closed double-screw compressorQtySet1111122222Startup typeY-#Power Supplyv/ph/hz380/3/50CondenserTypeWater cooled shell-tube typeQtySet1111122222EvaporatorTypeFlooded typeQtySet1111111111RefrigerantTypeR134aLubricantCodeEK03FillingL5055556060100110110120120Temperature controlPID control over water temperatureOuter diameter of chilled water inlet/outlet pipediameter mm219.1219.1219.1219.1219.1219.1219.1219.1219.1219.1Outer diameter of cooling water inlet/outlet pipediameter mm168.3168.3168.3168.3168.3219.1219.1219.1219.1219.1Weight of a single indoor unitkg5050525053505450560095109900100701027010580Operating Weightkg548056805780588060501025010650108101101011310Rated current (cooling)A263293345420466526586689840933Rated current (heating)A33537644353859867075288610761196Startup currentA749882135813581388749882135813581388Max startup current (cooling)A74988213581358138810121175170217781854Max startup current (heating)A74988213581358138813471551214523162452Note:1.Working conditions for nominal cooling capacity: inlet/outlet water temperature in the evaporator:12/7 degree; inlet/outlet water temperature in the condenser 30/35 degree2. Working conditions for nominal heating capacity: water flow in the above table;inlet/outlet water temperature in the condenser:40/~ degree;inlet/outlet water temperature in the evaporator 20/~ degree (note:antifreeze is required when water temperature in the water circuit is lower than 3 degree in winter)3. The pressure drop of condenser and evaporator don't include resistence from external water pipes and parts.4. For on-site electric wiring,see the nameplate or installation manual of the unit
