Screw chiller is mainly applied to building industry and industrial cooling process in molding of plastic film and PE plastics bag or other industries. The chiller will greatly improve quality of molded products and shorten period of injection molding cycles.
The water cooled screw chiller is made up of compressor, evaporator, condenser, refrigeration accessories, electric control system and so on. It will need auxiliary equipment to provide cooling water for the chiller heat exchange. Auxiliary equipment includes: cooling water tower, circulating water pump, double layer stainless steel insulated tank.
The air cooled screw chiller is used the fan to dissipate heat, so it is used the finned condenser to continuously heat exchange with the air. Therefore, the air cooled screw chiller does not need cooling water tower, but it needs circulating pump and double-layer stainless steel insulated water tank.
Evaporator – water or air enters the chiller system. Through the use of refrigerant, it is transformed into a low-pressure gas.
Compressor – takes low-pressure gas and compresses it to a higher pressure, which in turn allows it to flow through to the next step, the condenser.
Condenser – the high-pressure gas is cooled by refrigerant, whereby it converts back to low-pressure liquid form.
Expansion Valve – the liquid returns to the expansion valve and is directed back to the evaporator, and the cycle is repeated.
• Adopt the brand high efficiency screw compressor, such as: Bitzer, Hanbell, Carrier, Trane.
• High efficiency shell and tube evaporator.
• Adopt the 304 SS water tank to prevent corrosion and rust.
• PID controller system can maintain accuracy within 0.1℃, convenient operation.
• Imported electrical accessories, OMRON、FUJI、TE、LG、ABB、SCHNEIDER、SIEMENS etc.
• Unit equipped with the 304 SS water circulating pump according to the cooling capacity.
• Multiple safety devices protection and fault display system improvement, maintenance no need the professional personnel.
• RS485 communication, which can realize automation management.
• PLC control, high reliability, strong anti-jamming capability.
• Explosion proof design of electric control cabinet and pipeline.
• Various refrigerant R22,R407C,R410,R134A,R404A.
The above model of air cooled chiller is for reference only. Please contact market@njstartemp.com for specific selection, parameters and price
 | 1. PID controller (PLC controller optional) ▪ PID controller can clearly displays the actual cold water inlet temperature and set temperature, easy to accurate operate within 0.1℃. ▪ The control water temperature range from 5deg.C to 35deg.C. ▪ The functions of real-time alarms. |
2. Brand electrical components ▪The machine adopts famous brand electrical components, such as: Siemens, Schneider, LS, Omron, ABB, West... ▪ Brand electrical components integrates control and protection functions in one, powerful overload and short circuit protection, to ensure that the machine electrical line is safe and stable running, technical liability of the machine and quality guaranteed. |  |
 | 3. 304 Stainless steel water pump and water tank, Screw compressor ▪ 304 Stainless steel water pump and water tank can keep accurate temperature level and its ensure corrosion-resistant, no leakage and long working lifetime. ▪ Brand Copeland compressor, with lower noise, less vibration and more good cooling effective. |
4. High efficiency shell and tube type evaporator and condenser ▪ Shell and tube type evaporator with high-precision internal threaded copper tube design, More larger heat exchanging area, higher efficiency cooling temperature and maximize system performance. ▪ Shell and tube type condenser for quickly heat radiation. It is the better choice in hot summer. |
