Stationary Electric Screw Compressor

KAISHAN is one of the leading suppliers of stationary electric screw compressor on the Chinese market. Our electric compressors have been widely recognized by our cutomers. The product advantages have been listed below. Feel free to contact us for any questions about our air compressor.

1. Low operating cost
The air output can be steplessly adjusted within the range of 0-100%. When the air consumption decreased, the air output and motor electric current will also decline. If no air is consumed, the compressor will be in idling, and then stop automatically after long-time idling. When the air consumption starts to increase, the compressor will start automatically. Thus a great energy-saving performance can be achieved.

2. Excellent environmental adaptability
The stationary electric screw compressor comes with a great cooling system, making it suit high temperature and high humidity working environment. Good vibration isolation and noise reduction technologies have been applied. So no special base is needed for the installation, and only a small space will be enough for the air circulation and machine maintenance.

3. Great electric control system
Our stationary electric screw compressor is controlled by a intelligent microcomputer control system which has powerful fault diagnosis and protection functions. This system can work 24h a day without human monitoring. Once a fault is detected, suitable measures with be taken immediately, reminding you to replace the broken parts and make necessary maintenance. The operation is quite use-friendly-you can activate the automatic operation status by touching the corresponding area.

4. Optional frequency conversion function
The frequency conversion function is available if you need. The parameters of our frequency conversion type stationary electric screw compressor include 5.5-280kW motor power, 0.6-45m3/min air flow, 0.5-1.3MPa working air pressure. In addition, the air cooling device and water cooling device are optional, and the belt driving mechanism and direct connection mechanism are also available.

The frequency conversion screw air compressor has a range of features. The most effective energy saving method is to make the air o equal to the air consumption. Conventional air compressor adjusts the air flow by loading/deloading, shutdown/startup, or meter-in flow control valve. However these methods have low precision and need high frequency movements of valve and electric component. The frequency conversion type stationary electric screw compressor controls the air flow by altering the motor's rotating speed. Thus the air output can change precisely in accordance with the air consumption, and the movement frequency of the valves and electric components can be greatly reduced.

Two significant advantages of the frequency conversion type screw compressor are high energy efficiency and high reliability. The optimum working air pressure can be achieved by setting suitable frequency conversion pressure which is usually lower than the maximum working pressure (discharging pressure). Thus the stationary electric screw compressor will have better performance and less leakage risks.
