High Light nitrogen-filled precision oven ，oxygen-free industrial test chamber ，anti-oxidation heat treatment oven
Walk-in Nitrogen-Filled Oxygen-Free Precision Oven
HeJin's walk-in nitrogen-filled oxygen-free precision oven delivers ultra-uniform, low-oxygen heat treatment for automotive, electronics, and aerospace components. As a professional environmental test chamber source manufacturer, we provide custom solutions to boost product reliability, reduce scrap rates, and meet global industry standards.
Product Overview
Our Walk-in Nitrogen-Filled Oxygen-Free Precision Oven is a state-of-the-art industrial precision heat treatment and environmental test system designed to create a high-temperature, low-oxygen/oxygen-free, clean, and uniformly distributed temperature field for large-scale or batch workpieces.
The system uses high-purity nitrogen (≥99.99%) to displace ambient air, creating a fully inert protective atmosphere that eliminates oxidation, discoloration, and surface degradation of sensitive components during high-temperature drying, curing, heat treatment, and reliability testing. The walk-in design features a spacious interior that accommodates manual entry or trolley-mounted batch workpieces, making it ideal for both small-batch prototype validation and high-volume mass production.
Product Features & Core Benefits
  • Precision Oxygen-Free Atmosphere Control: Achieves ultra-low oxygen content down to ≤10ppm (standard ≤100ppm) via high-efficiency nitrogen displacement technology, preventing oxidation and surface degradation. Equipped with precision nitrogen flow control and real-time oxygen monitoring.
  • Industry-Leading Temperature Precision: Intelligent digital temperature control system with accuracy of ±0.1℃ to ±1℃ and temperature uniformity of ≤±2℃ across the entire chamber. Supports programmable temperature and atmosphere linkage control.
  • Spacious Walk-In Design: Generous interior capacity accommodates large workpieces or high-volume batch processing with trolley-compatible design. User-centric double-door structure with ergonomic layout for easy operation and maintenance.
  • Robust Multi-Layer Safety Systems: Dual protection design with explosion-proof vents and explosion-proof door structure. Independent over-temperature alarm system, short-circuit protection, over-current protection, and real-time fault monitoring.
  • Durable, High-Quality Construction: Exterior cabinet fabricated from high-quality cold-rolled steel with durable color electrostatic spray finish. Interior chamber and components made of premium SUS304 stainless steel for contamination-free environment.
International Compliance & Reference Standards
  • IEC 60068-2-2:2007 (Environmental Testing – Part 2-2: Tests – Test B: Dry Heat)
  • ISO 9001:2015 Quality Management System
  • GJB 360.8-87 (Test Methods for Electronic and Electrical Components – High Temperature Life Test)
