Joint Venture with The Conair Group, USA
A World Leader in Plastic Auxiliary Equipment Manufacturing
Screw Chiller
(Water Cooled Water Chiller)
Cooling Capacity from 30 TR to 200 TR Energy Efficient Central Chilling Plant.
Provide chilled fluid for industrial application from a central location with the Conair Water Cooled W-SK series central chillers.
Simple design of screw compressorsprovide both full load and part load efficiencies unmatched in the industry, and results in lower energy costs when compared to reciprocating compressors.
Screw Chiller (Water Cooled Water Chiller)
Option of eco friendly refrigerant (R134a) also availableHelical screw design results in part load performanceOnly four moving parts when compared to reciprocating compressors; there are no pistons, connecting rods, suction and discharge valves or mechanical oil pumpLatest heat transfer technology results in increased condenser and evaporator tube efficiencyReduced rotor clearance results in reduced leakage between the high and low pressure cavities during compressionResistant to liquid slugging; this compressor design can handle amounts of liquid refrigerant that would severely damage a reciprocating compressorDeveloped by Thermal Care � Group company of Conair Inc. USAUse of multiple Proportional Integral Derivative (PID) temperature control loops ensures consistent reliability, stability, and efficient operation by instantly reacting to fluctuations in system loadsFULL Screen Display � a simplified view of Chiller with larger display of SETPOINT and PROCESS temperatures that can be seen from a distance provides a quick glance to validate the operationClear language text display and graphic representation of unit components provides quick and easy understanding of unit operationControl on no. of ON / OFF cycle of compressor Controls and maintains stable and reliable operation of the chiller through use of an extensive array of sensors, actuators, relays, switches, and control algorithms User friendly screen for operatorCommon locations for most adjustment or settingsDetailed description for each settingProcess supply water above high temperature alarm set point Process supply water below low temperature alarm set point Status banner of start-up and shut-down sequences Compressor ON / OFF cycle control
Unique FeaturesRugged compressor design with only four moving parts eliminating the need for pistons, connecting rod, wrist pins and valves. Less moving parts means less internal friction and greater efficiencySemi hermitic screw compressors with two shaft designs with suction and discharge solder connection, integrated check valve, integrated pressure relief valves, flanged on oil separator, oil heater, oil filter and oil sight glassAll chilled water contact surfaces are non ferrous for protection against corrosion. All wetted surfaces are stainless steel, copper or other non ferrous materialSmall unit size, factory wired, easy lifting procedure, easy start up logicStainless Steel Brazed Plate Heat Evaporator with option of Shell & Tube Evaporator designed for high surface area and rapid response (capacity up to 60 TR)Shell & Tube Evaporator with option of Stainless Steel Brazed Plate Evaporator designed for high surface area and rapid response (capacity of 75 TR and above)Strainer protects the evaporator from solid contaminations in the process waterFlow switch is used to detect flow loss for safety of evaporator when return water flow is lowElectronic expansion valve is used to regulate the flow of refrigerant in the evaporator as per the load of system to maintain the suction superheatShell & Tube type water cooled condenser for Indian ambient condition with externally finned copper tubeRemovable cartridge type filter dryer to ensure moisture free system and quick change featuresSight glass indicates the status of dry or moist systemPressure switch protects the compressor against low and high pressureMonitoring of suction and discharge refrigerant pressuresAntifreeze protection to safe guard the evaporator & compressor against low temperature
