PSA Nitrogen Generator 10Nm3/H 99.99% Purity for Annealing Furnace Atmosphere Protection

PSA Nitrogen Generator 10Nm3/H for Annealing Furnace Atmosphere

The GASPU N2-HT-10 is a compact PSA nitrogen generator designed for annealing furnace atmosphere protection in metal heat treatment workshops. Supplying 10Nm3/H of nitrogen at 99.99% purity with dew point ≤ -60°C, it protects tool steel, die steel and alloy parts from oxidation and decarburization during annealing and bright heat processing.

Key Features & Competitive Advantages

• Furnace Atmosphere Grade Purity: 99.99% nitrogen with ultra-low dew point for protective annealing atmospheres.
• Small Footprint for Workshop Layout: Compact skid design fits easily beside existing furnaces, no civil works required.
• Fully Automatic PLC Control: One-button start, automatic purity compensation and alarm output for unattended heat treatment shifts.
• Low Operating Cost: On-site generation saves 30-50% versus liquid nitrogen or cylinder supply for small furnaces.
• Industrial Durable Build: Seamless steel pipelines, hybrid steel frame, CE and ISO 9001:2015 certified.
