Pharmaceutical Nitrogen Generator

The pharmaceutical nitrogen generator is an on-site nitrogen system designed specifically for pharmaceutical manufacturing. Unlike liquid nitrogen tanks or cylinder supply, this equipment uses Pressure Swing Adsorption (PSA) technology to generate nitrogen directly at the point of use, eliminating supply instability, high transportation costs, and safety risks.

In pharmaceutical production, nitrogen often contacts drug products directly. Shenger Gas pharmaceutical nitrogen generators feature a fully stainless steel structure with mirror-polished adsorption tower interiors and orbital welded connections to eliminate dead spots. The system complies with cGMP standards and can be deployed in both classified and non-classified areas.

Principle & Structure

The system operates on PSA technology. Two adsorption towers filled with carbon molecular sieve work alternately. When pre-treated compressed air enters one tower, oxygen and moisture are adsorbed, allowing nitrogen to pass through. Once saturated, the system switches to the second tower while the first regenerates.

Core modules:

• Air treatment: Coalescing filters, refrigerated dryer, and activated carbon filter ensure oil-free, dry inlet air
• Separation: Two stainless steel towers, pneumatic valves, and controller with precision molecular sieve filling
• Buffer & distribution: Stabilizes pressure; can add precision filters, regulators, and flow meters

Technical Specifications

Operating temperature: 5℃ – 45℃ ambient; inlet air ≤ 35℃ for optimal efficiency.

Energy consumption: At 99.9% purity, approximately 0.4 – 0.6 kWh/Nm³. Energy-saving control adjusts operation based on actual demand.

Industrial Applications

The pharmaceutical nitrogen generator serves critical production stages:

• Solid dosage: Material conveying and protection for blenders, tablet presses, capsule fillers
• Sterile products: Sterile nitrogen for preparation systems, filling lines, lyophilizers
• Biopharmaceuticals: Nitrogen blanketing for fermenters and storage tanks
