Product Description

Description:

The series water chiller adopts efficient semi-closed screw compressor. the compressor adopts a 5:6 asymmetric high-efficiency screw rotor, which is graded or steplessly energy regulated. It is automatically adjusted according to load changes and is more energy efficient. The unit heat exchanger adopts high-efficiency heat exchange tube to improve the refrigeration efficiency, and the unit is equipped with multiple protections to make the unit operate safely and reliably.

Features of chiller:

1. Energy with high efficient

2. Operation noise and vibration is low

3. No friction loss

4. Low starting current

5. High system sustainability

6. Environmental protection

Safety system:

1 Compressor reverse protective

2 Freeze protector protective

3 Refrigerant safety valve

4 Buzzer

5 High-pressure gauge and Low-pressure gauge

6 Power phase failure protector

7 Coil over-heat protector

8 Temperature auto-switch

9 Refrigerant shortage protective

Note:

1. Above cooling capacity parameters are all based on the conditions of condensation temperature 40℃, evaporation temperature 2℃.

2. We can make order according to your requirement.

3. Please indicate the hot recycled if needed, as the recycle rate can be up to 25%-30% of the unit refrigerating capacity, the temperature can be up to 55℃.
