Hot N2 Heater

Hot N2 is a gas heating system specifically engineered for nitrogen. It precisely heats high-purity nitrogen to a set temperature, delivering a stable, high-temperature nitrogen stream. Designed with a clean, oil-free architecture, it ensures no contamination of pipelines or workpieces. Featuring high-precision temperature control and rapid thermal response, it is widely used in processes such as semiconductor manufacturing, electronics fabrication, cleaning, drying, purging, and reflow soldering.

Features

• Purpose-built for nitrogen heating with a clean-flow design; compatible with high-purity nitrogen, free from impurity outgassing, and ideal for contamination-sensitive processes.
• High-precision temperature control ensures stability and minimal fluctuations, meeting stringent constant-temperature process requirements.
• Rapid heating capability with a sensitive thermal response, allowing for quick attainment of target temperatures.
• Isolated internal heating elements with an optimized layout to prevent localized overheating and avoid nitrogen degradation.
• Equipped with multiple safety protections—including overheat protection, flow-loss protection, and fault alarms—to prevent dry-heating damage in the event of a gas supply interruption.
• Compact footprint allows for seamless integration into production line tooling or chamber purging stations, ensuring easy installation.
• Designed for continuous, long-term operation, making it well-suited for uninterrupted purging and drying tasks on automated production lines.
• Available in various outlet configurations and flow rate ranges, catering to applications from precision, low-flow processes to high-volume purging operations.

Applications

• Hot nitrogen drying and solvent purging in semiconductor, FPC, and PCB manufacturing.
• Hot-air drying of wafers, optical components, and precision parts following cleaning processes.
• Provision of a high-temperature nitrogen atmosphere for soldering and flux-based processes to prevent oxidation.
• Supply of constant-temperature nitrogen environments for laboratory and R&D equipment.
• Nitrogen purging and auxiliary heating for curing in thin-film and coating processes.
