Cameron (Cooper) Oil‑Free Centrifugal Compressors Overview

Brand & Heritage

Cameron (formerly Cooper Turbocompressor) has manufactured oil‑free centrifugal compressors since the 1950s and is recognized as a category leader aligned with API 672 practices. Installations span steel, petrochemicals, air separation, pharma, glass, electronics and many more industries worldwide.

Series & Flow/Pressure Ranges

Core air series include TA2000/2020/3000/6000/9000/11000 and high‑pressure A2040/6040; the MSG family and blowers cover larger duties. Approximate coverage ranges from ~14 to 20,000+ m³/min and discharge pressures from ~1 to 80+ bar(g), depending on series and service.

Why Oil‑Free Centrifugal

100% oil‑free air, inherently low vibration and noise, long service life (25+ years typical), and very low routine maintenance. IGV modulation and efficient aerodynamics provide wide turndown and meaningful energy savings versus throttling alternatives.

Package Philosophy

Skid‑mounted compressors with intercoolers, lube system, controls and auxiliaries simplify installation and O&M. Single‑level layouts reduce footprint and civil cost; factory testing and clear scope reduce project risk and startup time.

Core Components

Each stage uses a dedicated casing with inlet, diffuser and volute; 17‑4PH stainless open impellers are over‑speed tested and dynamically balanced. Horizontally split gearcase houses helical gears to AGMA quality, with tilting‑pad/journal bearings and robust shaft seals.

Seals & Oil‑Free Integrity

Non‑contact labyrinth gas seals isolate process gas from lubricated bearings with an atmospheric buffer space; oil seals and deflectors prevent oil migration, ensuring truly oil‑free discharge.

Inter/Aftercoolers

Shell‑and‑tube coolers with extractable bundles enable mechanical cleaning; finned‑surface arrangements enhance air‑side heat transfer on relevant models. Moisture separation and auto drains minimize carryover and fouling.

Lubrication System

Forced‑lube system with main shaft‑driven pump and auxiliary electric pump for start/stop and low‑pressure backup. Oil tank with heater and thermostatic control maintains viscosity and bearing reliability under all conditions.

Controls, Start‑up & Protection

Constant‑pressure control through inlet guide vanes meets varying demand; blow‑off protects the machine at low flow. Anti‑surge logic, vibration/temperature monitoring, and comprehensive trips/alarms secure safe operation from start‑up through steady state.

Applications & Total Cost

Suitable for continuous, clean‑air utilities and many process‑gas duties. The energy efficiency, oil‑free quality and low maintenance combine to deliver attractive total cost of ownership compared with oil‑free screw alternatives in high‑flow regimes.
