KIMAIR PHE Series Medium-pressure Two-stage PM Motor Inverter Rotary Screw Air Compressors

The PHE series represents the pinnacle of medium-pressure air compressor technology, deeply integrating "Two-Stage Compression" with "Permanent Magnet Variable Frequency Drive." It is specifically designed for higher pressures of 1.4-1.6 MPa or for medium/high-pressure applications with extreme demands for energy efficiency. Through staged compression and intercooling, it significantly reduces the single-stage compression ratio and discharge temperature, achieving a revolutionary energy efficiency breakthrough and exceptional reliability in the high-pressure range. It is the ultimate choice for high-end medium-pressure applications, meeting the most stringent industrial demands.

KIMAIR Core Advantages

Energy Efficiency Champion in High-Pressure Range

- Above 1.4 MPa, the energy efficiency advantage of two-stage compression is extremely significant, saving 15%-30% energy compared to single-stage medium-pressure compressors.
Ultra-Low Operating Temperature

- Inter-stage cooling significantly lowers the final discharge temperature, approaching ambient temperature. This results in longer oil life and extremely high airend stability.
Wide Pressure Adaptability

- Stably covers a broad range from medium to high pressure (up to 4.0 MPa). Allows one machine for multiple uses, offering strong adaptability.
Top-Tier Configuration & Intelligent Control

- The entire series uses top-tier core components and is equipped with the most advanced intelligent management system, supporting complex working conditions.

Customer Frequently Asked Questions (FAQ)

Q: Is maintenance much more complex for a two-stage medium-pressure compressor?

A: The maintenance items are slightly increased (adding one stage of compression components and an intercooler). However, KIMAIR uses a symmetrical and modular design, making the maintenance logic clear. The significant energy efficiency gains, longer equipment life, and higher operational stability fully justify the slightly increased maintenance complexity. We provide professional maintenance guidance and support services.
