Product Description
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, etc.

Unit main parts include Semi-hermetic screw compressor, oil separator, condenser, economizer, evaporator and control system.

Design features:

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.Air Cooled Low Temperature Screw Chiller
