Air Cooled Screw Chiller Central Air ConditionerCompany ProfileSENDO is a professional manufacturer of quality air conditioning products.Sendo could supply most products in HVAC field, such as Rooftop Packaged Unit, Split Commercial Unit, Air Cooled Water Chiller, Water Cooled Water Chiller, Chilled Water Air Handling Unit and Fan Coil Unit etc.Sendo also supplies made-to-measure HVAC solutions. We engineer and manufacture Air Conditioner to suit the building design and application.  Air Cooled Screw Chiller & Heat Pump18 basic models with cooling capacity ranging from 196kW to 1164kWR134a friendly refrigerant has no ozone-depletion potentialColors can be ordered in either white or dark grey.FeaturesReliable Operation1. All parts and control components of the unit are provided by world-famous reliable suppliers to make the unit highly efficient, energy saving, and reliable, such as Bitzer Comp. & Danfoss EXV, Schneider electric etc.2. The unit uses the advanced electronic expansion valve, which ensures excellent performance both under full load or partial load and higher control accuracy (Optional)3. Each unit was extensively tested before delivery to verify its operational reliability and to ensure a smooth startup.Easy and Fast Installation 1.  The water pipe of the water-side heat exchanger has been equipped with water flow switch and is ready to use, which saves the job site installation time. Inlet and outlet pipes are equipped with flange connection, which makes the on-site installation easier. 2.  The Chiller comes with the startup cabinet and control cabinet and has been filled with refrigerant and refrigeration oil before delivery. The chiller can be placed in service after being connected with power supply and water supply during field installation. 3.  The built-in hydronic module is optional. This module integrates all necessary hydronic components such as water pump, filter, expansion tank, flow switch, safety valve, pressure gauge, and drainage valve.Components1. High efficiency Bitzer screw compressor, Hanbell screw compressor is optional.2. High efficiency heat exchanger. Condenser adopts the copper tube & hydrophilic aluminium fin coil type structure, the appearance is V-shape. This design increase the heat exchange area, reduce the temp. differences, thus increase the heat exchange efficiency by 20%. Evaporator built with high efficiency shell & tube type heat exchanger, factory insulated with flexible close cell material.3. External rotor type axial fans, equipped with three phase direct drive motors, low noise 8 poles, protection level IP54, provided with a protective outlet grille.4. Electric panel consist of: compressor contactor, fan motor contactor, compressor isolating switch, fan protection breaker, phase sequence relay and microprocessor with function display. All of them are Schneider Electric brand.OptionColors can be ordered in either white or dark grey;Cooling only or heat pump;Refrigerant is optional;Capacity can be ordered based on projects actual demand;Low ambient temperature cooling;Process cooling unit - Provide customized inlet/outlet water temperature condition;Total or partial heat recovery;Top-level efficiency free cooling;Optional golden fins for some area need special anti-corrosion;Build-in hydronic module;Scroll R410A compressors.    Specification  ModelUnit200250300320360400Cooling Capacity *kW196238306340358405Cooling Power InputkW62.777.294.6103.2112.2124.5Heating Capacity **kW213257339362385446Heating Power InputkW61.275.493.6100.7109.5123.2Power Supply/380~415V/3Ph/50HzRefrigerant/R134ACompressorType/Semi-hermetical Screw CompressorQty/Refrigerant CircuitNos1/11/11/11/11/11/1Cooling Power Input *kW56.768.485.692.8100.4111.3Heating Power Input **kW55.266.684.690.397.7110.0Energy Adjustment%25%~100%25%~100%25%~100%25%~100%25%~100%25%~100%Water Side Heat ExchangerType/High Efficient Shell & Tube Heat ExchangerWater Flow Ratem3/h33.7 40.9 52.6 58.5 61.6 69.7Water Side Pressure DropkPa454546464865Connect Pipemm8080125125125125Air Side Heat ExchangerType/Copper Pipe + Anticorrosion Aluminium FinFan Type/Axial / DirectFan Motor NumberNos446666Air Flowm3/h88000112000132000144000156000168000Power InputkW4x1.54x2.26x1.54x1.5+2x2.22x1.5+4x2.26x2.2Sound Pressure Level ***dB(A)808079798182Net Weightkg246027803450355037203960  ModelUnit430470500520570610Cooling Capacity *kW411465490515554574Cooling Power InputkW128.4143.0152.7157.0169.2176.2Heating Capacity **kW442513526566610611Heating Power InputkW125.3141.5149.0155.4167.4172.0Power Supply/380~415V/3Ph/50HzRefrigerant/R134ACompressorType/Semi-hermetical Screw CompressorQty/Refrigerant CircuitNos1/11/11/11/11/11/1Cooling Power Input *kW115.0128.2136.5139.4151.4155.6Heating Power Input **kW111.9126.7132.8137.8149.6151.4Energy Adjustment%25%~100%25%~100%25%~100%25%~100%25%~100%25%~100%Water Side Heat ExchangerType/High Efficient Shell & Tube Heat ExchangerWater Flow Ratem3/h70.7 80.0 84.3 88.6 95.3 98.7Water Side Pressure
