Dual machine,dual stage

Product Introduction

Advantages of DASEN NH3 Double Machine Double Stage Screw Compressor Unit:

1： Intermediate pressure with bypass load, achieving simultaneous operation of quick freezing and pre cooling dual temperature conditions:

The high-temperature section of the two-stage machine can balance the load of the pre cooling section, achieving simultaneous cooling for both pre cooling and quick freezing equipment on the production line.

There are 0~4 ℃ refrigerated rooms, cooling rooms, etc. in the production and processing workshop, and this load can also be handled by the high-pressure stage head of the two-stage machine.

2、 Energy saving operation: The dual stage system is equipped with two heads, divided into a low pressure stage and a high pressure stage. Each head shares a smaller pressure ratio, resulting in more stable operation and higher COP.

3、 Adjustable content ratio: The content ratio of high-pressure stage machine heads with large cooling capacity can be adjusted to achieve different pressure ratios under different environmental temperatures in winter and summer, avoiding the existence of over compression and under compression of the machine head,

While improving the service life of the unit, the operation is also more energy-efficient.

4、 Single head installation with low power: The pry block is compressed in two stages by two heads, each with a smaller motor power and equipped with a variable frequency motor, resulting in a smaller starting current. It is particularly suitable for new construction, renovation, etc

For food processing plants with significant limitations on instantaneous start-up power.

5、 Efficient oil separation: Equipped with a high-efficiency horizontal oil separator developed by DASEN, it achieves an oil separation effect of 10ppm, reduces the flow of lubricating oil into the end heat exchanger, and improves heat transfer efficiency.
