VSB-25 Saving energy variable frequency inverter rotary screw air compresor 8 bar air compressor

CART frequency conversion use special inverter systems, adopt the newest technology of IGBT4 Industrial-grade chips,  it is reliable ,thermostable and long life. Energy savings have achieved the international advanced level.

VSB series(Direct drive)screw compressor technical data(5.5kw-22kw)

Frequency screw air compressor energy conservation principle:

Because motor’s speed and air compressor consumed power are first power relationships, reducing the motor’s speed are same as reducing power consumption. Frequency screw air compressor use gas pressure and gas consumption in pressure sensors in real time detection system. By the controller and drive the PID regulator for precise control, without changing the compressor motor torque(the ability to drag load) in the case of changes in the speed of air compressor (the output power),thereby adjusting the system pressure of the compressor and meet output air demand. When the system gas consumption decreases, the compressor provides greater gas consumption in the system, the inverter automatically reduces the compressor’s speed. Otherwise, in order to increase the compressed air, increase the motor’s speed. Keeping the system stable pressure and achieving constant pressure air supply.

Frequency conversion screw air compressor advantages:

4,Improve the gas production efficiency, air production increase about 5%-15%:

Avoid the frequent loading, unloading, stop and save energy.

5,The working years will be extended, from the general 10-15 years to 15-30years.

(1)Variable frequency soft start

(2)flat run

(3)Non-frequency device to prevent electrical contact failure

6,Improve the efficiency of transformer and power grid:

When the common units start or load, Current fluctuations will affect the electricity grid and other equipment, variable frequency compressor will reduce to a minimum, thereby enhancing the effectiveness of the transformer and the power grid.

7,reduce noise:

In routine conditions,  the inverter compressor rate motor speed is 60% to 90%, when the compressor run, effectively reduce the noise . Through field tests showed that, compare with normal air compressor,  the noise of variable frequency compressor decreased by about 2-10 db.

8,high ratio of performance:

CART variable frequency air compressors not only bring energy saving and production efficiency, but also have cost-efficient.

9,high quality:

Adopt well-known brand inverter, industrial-grade components, environmental adaptability, reliability and durability.
