Atlas Copco Compressor Cooler ZH9000

1. Product Overview

As a global leader in industrial productivity solutions, Atlas Copco's ZH9000 cooler serves as the core thermal management component specifically designed for large oil-free centrifugal air compressors within the ZH+/ZH series compressor systems. This water-cooled unit integrates with compressor hosts, Elektronikon® intelligent control systems, and MD/ND drum dryers to form a closed-loop energy-saving system, primarily serving industries with stringent compressed air quality and energy efficiency requirements such as glass manufacturing, automotive production, steel smelting, and petrochemical processing.

The ZH9000 cooler features modular design for seamless integration with compressor bodies, utilizing stainless steel oil coolers and cooling water manifolds to create dual-circuit heat exchange systems capable of handling thermal loads at 5500-42500m³/h flow rates. Certified to ISO 8573-1 CLASS 0 standards, it guarantees oil-free compressed air output, eliminating risks of pipeline corrosion, equipment failure, or product quality issues caused by oil contamination.
