HTSL series low temperature screw chiller is widely adopted in manufacturing process in industries such as non-ferrous smelting, chemical and pharmaceutical, petroleum chemistry, grain and oil, food and beverage, mechanical, electric, air separation, elc.
Unit main partsinclude semi-hermetic screw compressor, oil separator, condenser, economizer, evaporator and control system.
 

• Coolant temperature range from 5o C to -40o C.
• High efficient semi-hermetic twin-screw compressor adopted, high COP, steady performance and long service life.
• Compressor stepped capacity control, minimize starting current and impact to grid.
• 25%-100% continuous capacity control, ensuring compressor full performance, saving running cost for customers.
• High accuracy touch screen and imported PLC controller adopted.
• Multi-protection function: Compressor discharge over temperature, motor over temperature, anti-freezing, over current, phase sequence, high/low pressure, flow switch.
• Mass Storage PLC, allows permanent reservation of more than 100 fault records, precisely monitors unit running state.
• Pass word setting, avoids unit from shut down or damaged by accidental factor.
• Control components including thermal expansion valve, solenoid valve, check valve are supplied by international brand, ensuring steady and efficient running under wide range of working condition.
• Units are completely tested and operated at full load, leave factory with refrigerant, can be start once water and power is connected.
• Compressor with built-in exhaust pot silencer ensures low noise running.
• Corrosion-resistance water system upon request.
• Refrigerant option: R22, R407C, R404A, R134A and R410A.
