INVT GD350A helps the compressor industry achieve efficient and energy-saving operation

1. All wheel drive and versatile, suitable for various compressor loads
Compressors are divided into various types such as screw, piston, centrifugal, etc., with significant differences in load characteristics. The INVT GD350A frequency converter supports G/P integrated design, and can perfectly adapt to both constant torque screw compressors and variable torque centrifugal compressors; Its excellent vector control performance can achieve smooth starting of the compressor, avoiding damage to the power grid and equipment caused by the impact of starting current.

2. Flexible expansion to achieve intelligent control of compressors
Modern compressors require functions such as constant pressure gas supply and remote monitoring. The INVT GD350A can be extended with an analog I/O card, which can be connected to pressure and temperature sensors to achieve closed-loop constant pressure control; Through the EtherNet/IP communication card, the factory automation system can be connected to achieve remote start stop, parameter adjustment, and operation data monitoring of the compressor, improving the automation level of the compressor.

3. Convenient operation and maintenance, reducing equipment maintenance workload
The compressor usually runs continuously for 24 hours, making maintenance difficult. INVT GD350A supports fault recording card expansion, which can record parameters and operating waveforms at the time of fault occurrence, providing detailed data for fault analysis; The standard real-time clock function can accurately record the time of fault occurrence, facilitating the development of maintenance plans. Simultaneously supporting local and remote firmware upgrades, system optimization can be completed without downtime.

4. Energy saving and reliable, reducing the operating cost of compressors
The compressor is a major consumer of industrial electricity, and INVT GD350A adopts a new energy-saving algorithm to automatically adjust the output power according to load changes. Compared with traditional power frequency operation, the energy-saving rate can reach 20% -50%. The product is equipped with a built-in DC reactor, which can improve power factor and reduce harmonic pollution in the power grid; At the same time, through rigorous reliability testing, the compressor can maintain stability even under long-term continuous operation, reducing equipment failure rates.
