Nitrogen

Knox Western designs and manufactures reciprocating Nitrogen Gas Compressors engineered to meet the most demanding operating conditions while maintaining maximum gas purity. Each unit is built in compliance with API 618 standards, ensuring adherence to globally recognized benchmarks for design integrity, safety, and long-term reliability.

‍

Technical Features:

‍

• Oil-Free Compression: Our compressors utilize non-lubricated cylinder designs to eliminate the risk of hydrocarbon contamination, enabling the delivery of ultra-high-purity nitrogen.
• API 618 Design Basis: Full compliance with API 618 covers rotor dynamics, pulsation control, and mechanical integrity—delivering predictable performance across continuous duty cycles.
• Bone Dry Gas Capability: Specifically designed to compress bone dry nitrogen (dew point < –70°C), where moisture and contamination cannot be tolerated.
• Robust Materials & Construction: Critical wetted parts are engineered with corrosion-resistant alloys and precision machining to ensure stability when handling inert and non-reactive gas streams.
• Modular Configurations: Flexible frame and stage arrangements allow optimization for required discharge pressures, flow rates, and duty conditions.

‍

Application Areas:

‍

Knox Western Nitrogen Compressors are deployed in a wide range of industrial and process environments, including:

‍

• Petrochemical & Refining: Inerting, blanketing, and purging
• Cryogenic and Industrial Gas Production
• Pharmaceutical & Biotech: Contaminant-free compression
• Electronics & Semiconductor Manufacturing
• Energy & Power Generation

‍

By combining oil-free cylinder technology with API 618-compliant design principles, Knox Western ensures nitrogen compression solutions that deliver maximum uptime, purity, and operational safety in the most mission-critical environments.
