PSA Nitrogen Generator 20Nm3/H 99.99% Purity for Metal Annealing Bright Heat Treatment

PSA Nitrogen Generator 20Nm3/H for Metal Heat Treatment

The GASPU N2-HT-20 is a dedicated PSA nitrogen generator engineered for metal heat treatment, annealing and bright heat processing. It supplies continuous high-purity nitrogen at 99.99% with a low dew point, creating an oxygen-free furnace atmosphere that prevents oxidation, decarburization and scaling on metal surfaces.

Key Features & Competitive Advantages

• Annealing Atmosphere Grade Purity: 99.99% nitrogen with dew point ≤ -60°C, ideal for bright annealing and protective atmosphere heat treatment.
• Stable Oxygen-Free Blanketing: Advanced PSA technology with automatic purity compensation ensures consistent furnace atmosphere quality.
• Fully Automatic PLC Control: Touch screen HMI with one-button start, purity alarm and remote monitoring for unattended operation.
• Energy Efficient: Intelligent adsorption cycle management cuts compressed air consumption, lowering operating cost per Nm3 of nitrogen.
• Industrial Robust Build: Seamless steel pipelines, hybrid steel frame, CE and ISO 9001:2015 certified.
