Ammonia Refrigerating Units 

Screw refrigeration compressor unit structure features:
1.Adopts high-efficiency oil separator and high efficient oil cooler, ensure units low fuel consumption and higher heat exchanger efficiency.
2. All are made of steel valves, make operability and security of equipment get further   guarantee.
3. Increase constant pressure valve on the pipe, make the pressure of oil supply stable, and improve the use of whole machine performance.

4. Reasonable unit gravity and the anchor bolt position, further reducing the vibration and noise.
5. The unit pipeline system decorates concise, simple operation.

6. Prepare manual and microcomputer full automatic control two kinds of ways. The key components of control part adopt import products, good quality, and long life, further improve the reliability.

Controller is dedicated microcomputer controller, developed according to characteristics of screw unit. This controller compared with similar products, faster speed, higher reliability and stronger control function. It has achieved modular, networking. At the same time also has characteristic of beautiful appearance, convenient operation, friendly interface in man-machine, etc.
