KDSL series low temperature screw freezer is mainly used in process cold source cooling of non-ferrous metallurgy, chemical and pharmaceutical intermediates, petrochemicals, grain and oil, beverage and food, machinery, medicine, electronics, air separation and other production and processing.

The unit consists of a semi-closed screw refrigeration compressor, oil separator, condenser, economizer, evaporator and control system.

Design Features

The unit can supply low temperature chilled water from 5 °C to -40 °C.

The imported high-efficiency semi-closed twin-screw compressor has high energy efficiency, reliable operation and long service life.

The compressor segmentation capacity control effectively reduces the starting current and the impact on the grid.

25%-100% continuous energy regulation (stepless energy adjustment), to ensure the full performance of the compressor and help users to maximize operating costs.

Adopt high-precision large-screen touch screen, imported brand PLC controller.

Multiple protection functions: temperature protection of compressor exhaust over temperature, motor over temperature, cold water antifreeze, over current, phase loss, reverse equal electrical protection; refrigerant system high and low pressure, water cut and other state protection.

Large-capacity PLC storage can permanently save hundreds of alarm records and effectively monitor unit operation.

The password setting ensures that the device will not be shut down or damaged due to accidental factors.

The use of internationally renowned brands of thermal expansion valves, solenoid valves, check valves and other control components to ensure efficient and stable operation of the unit within a wide range of operating conditions.

After the product has passed the comprehensive inspection and full-load operation test of the manufacturer, it will be shipped with the refrigerant. The equipment can be started after the water and electricity are in place.

A patented exhaust gas eliminator is installed in the compressor to ensure low noise operation of the unit.

The salt water resistant corrosion waterway design is optional.

Optional refrigerant: R22, R407C, R404A, R134A, R410A.
