Core Features

Multi-Cylinder High-Pressure Configuration

The four-cylinder structure (4 × 75 × 55 mm) enables efficient compression of gases to high pressure levels, making it ideal for heavy-duty cooling tasks. Available in single-stage and multi-stage options, it accommodates pressure requirements ranging from low-pressure gas transfer to high-pressure industrial processes.

Positive Piston Locking Technology

Equipped with positively locked pistons, the compressor allows precise setting of end clearance, maximizing efficiency while reducing wear on piston and cylinder components. This design ensures long-term operational stability and consistent performance even under continuous use.

Corrosion-Resistant Critical Components

Critical parts such as crossheads (cast iron) and valve seats are made from corrosion-resistant materials, withstanding harsh operating environments (e.g., chemical cooling, high-humidity settings) and preventing galling or degradation over time.

Pressure-Lubricated Crankcase System

A pressure-lubricated crankcase with an integrated filter ensures continuous lubrication of internal moving parts (crankshaft, connecting rods, bearings). This minimizes premature wear, extends service life, and maintains optimal performance during extended operation.

Customizable Mounting & Configuration Options

Supporting OEM and custom solutions, the compressor offers flexible mounting options (skid-mounted or plant-specific layouts) and configurable parameters (refrigerant type, voltage settings). It adapts to unique project requirements, from standard industrial setups to specialized cooling systems.
