Oil-Inject Rotary Screw Compressors , Iran

Screw compressors are constructed from AISI 4140 forged steel with ion nitriding heat treatment. Male and female rotors feature asymmetric profiles machined to ±0.002 mm precision. Fixed compression ratios range from 5:1 to 13:1 with 91% to 94% volumetric efficiency. Air delivery capacity spans from 22 kW 30 HP at 3.5 m³/min to 355 kW 500 HP at 65 m³/min. Nominal working pressure is 7 to 15 bar with a maximum allowable pressure of 20 bar. A high-pressure oil injection system with hydraulic damping maintains rotor clearances at 0.05 mm. A two-stage oil/air cooling system brings discharge air to within 10°C of ambient temperature.

The housing is cast from GG25 grade cast iron with integrated cooling fins. A three-stage oil separator cyclone, coalescing filter, final cartridge reduces oil content to 3 ppm. An advanced PLC controller with PID module optimizes specific energy consumption SEC below 0.11 kW/m³/min. A slide valve capacity regulator modulates flow from 25% to 100% with a 1.5-second response. Acoustic noise level at 1 meter ranges between 62 to 72 dBA. An internal helical gear timing drive achieves 98.5% transmission efficiency. The overall design is guaranteed for 100,000 hours of operation with at least 80,000 hours until major inspection.You can order and buy Oil-Inject Rotary Screw Compressors from Iran by contacting us through whatsaap and email.
