Medium Size Industrial Screw Compressor Variable Speed Rotary Screw Compressor

Medium Size Screw Type Compressor Variable Speed With High Efficiency PM Motor

The biggest advantage of the permanent magnet frequency conversion air compressor is energy saving. Generally, it can save energy by 10%~35%. The amount of energy saving depends on the working conditions of the air compressor and the parameter setting of the frequency converter. The biggest factor is the working condition of the air compressor. When the customer's gas consumption fluctuates greatly, the energy-saving effect will be better. The most direct data is the ratio of the time of no-load to the total working time.

LTC Compressor is leading manufacturer of screw air compressor and can provide energy-saving PM VSD Screw Air Compressor (7.5KW~160KW) with high efficiency, stable working performance and longer lifetime.

6.Cooling System+Oil and gas separation system
Adopt high-pressure cooling system, high heat dissipation efficiency
High oil and gas separation efficiency, reliability, durability, reasonable structural design, and more convenient maintenance.

7.Intake Valve Assembly
The air intake valve can automatically adjust the air volume from 0 to 100% according to the requirements of the system air volume, and the pressure loss is small.

Advantages of PM VSD Screw Air Compressor:

Compared with general air compressors, permanent magnet variable frequency air compressors have three major advantages:

1. High efficiency, environmental protection and energy saving

At full load, the permanent magnet motor provides large air volume with the least energy consumption; when the load rate of the permanent magnet variable frequency air compressor is less than 20%, it can continuously maintain a high operating efficiency of 95%, achieving first-class energy efficiency. Compared with the industrial frequency air compressor, the energy saving is more than 39.7%; compared with the general frequency conversion air compressor, the environmental protection and energy saving are 10%.

2. Long life and durable maintenance-free

The permanent magnet frequency conversion air compressor uses a rare earth permanent magnet synchronous motor to drive the screw head, without loss of magnetism at 120°C, and has a service life of ten years. Its screw head and motor share the same spindle bearing, without transmission belts and couplings, and the transmission system is 100% efficient. The motor has no rolling bearings, which eliminates the potential problems caused by the rolling bearings of the motor.

3. Save maintenance costs

The volume of the permanent magnet motor is 1/2 smaller than that of the general three-phase motor head, and the weight is 1/3 lighter, and the entire mechanical specification is smaller. The screw head of the permanent magnet variable frequency air compressor is 1/2 smaller than the general head, and the lubricating oil required for each maintenance is about 50% of the general screw air compressor, which greatly saves the maintenance cost.
