Screw Air Compressor

Product Description

The PMS series screw compressor is a Class 1 energy-efficient permanent magnet variable frequency screw air compressor, designed for mid-to-high-end industrial users seeking high efficiency, energy saving, and stable reliability. Inheriting Geso's consistent precision manufacturing philosophy, this series achieves comprehensive upgrades in three dimensions: energy efficiency standards, transmission efficiency, and intelligent control, helping factories significantly reduce their total lifecycle operating costs.

PMS series compressors have core advantages.

High efficiency – National Level 1 energy efficiency + IE5 motor

■ The entire unit meets the national Level 1 energy efficiency standard, with a power-to-weight ratio superior to industry norms, resulting in significant long-term electricity cost savings.

■ Equipped with an IE5 energy-efficient air-cooled permanent magnet inverter motor, its efficiency surpasses IE4, maintaining high-efficiency output under all operating conditions.

■ The permanent magnet synchronous motor is directly coupled to the rotor, eliminating losses from gearboxes or belt drives and reducing potential failure points.

Convenient – Install and use immediately, worry-free operation and maintenance.

■ The compact design and small footprint make it suitable for station renovations or space-constrained scenarios.

■ Standard configuration includes a 485 communication interface and remote start/stop dry contacts, enabling rapid integration with user central control systems or IoT platforms.

■ The air-cooled structure requires no cooling water connection, making installation and debugging simple and convenient for both mobile and fixed use.

Intelligent – Vector frequency converter + fully automatic operation

■ It adopts vector control frequency conversion technology to adjust the speed in real time according to the gas consumption, and the pressure fluctuation is controlled within ±0.01MPa.

■ The intelligent control system automatically learns gas usage patterns, and the unloading and no-load loss approaches zero.

■ The touchscreen human-machine interface allows users to view operating parameters, fault records, and maintenance reminders, and supports local/remote switching.

Stable – Rigorous certification, durable for long-term use

■ The entire series has passed national energy efficiency certification, CE, GCCA, EAC and other authoritative domestic and international certifications, meeting export requirements.

■ Direct-drive transmissions have a simplified structure, eliminating belt slippage or pulley misalignment issues, resulting in a significantly lower failure rate compared to traditional belt-driven conveyors.

■ Key components are sourced from reputable brand suppliers, and the entire machine undergoes 100% load testing before leaving the factory.
