HCH Type Fully Automatic Nitrogen Purification Equipment
The HCH type fully automatic nitrogen purification equipment
utilizes advanced adsorption technology to remove oxygen, water,
and impurities from nitrogen gas. Starting with 99.9% purity
nitrogen as raw material, the system employs carbon and specialized
catalysts to achieve superior purification results.
Working Principle
The HCH type nitrogen purification equipment employs a
sophisticated combination of hydrogenation catalytic deoxygenation
and molecular sieve deep drying processes, specifically engineered
for SMT reflow soldering applications. Ordinary nitrogen enters the
system and is precisely mixed with trace amounts of hydrogen before
being directed to the catalytic reaction tower. Under the influence
of specialized catalysts, residual oxygen in the nitrogen reacts
with hydrogen to form water, effectively completing the
deoxygenation process.
Following deoxygenation, the gas undergoes initial condensation to
remove water content and then proceeds to the molecular sieve
drying system for deep removal of residual water vapor and minor
impurities. The molecular sieve features an automatic regeneration
system capable of continuous cyclic operation, ensuring 24-hour
uninterrupted equipment performance.
After completing the comprehensive purification process, the system
produces high-purity, low dew point nitrogen gas. All output
parameters meet the stringent requirements for SMT reflow soldering
oxygen-free applications, effectively preventing PCB pad oxidation
and ensuring superior soldering quality.
Equipment Introduction
The HCH type nitrogen purification equipment represents a high-end
gas purification solution developed specifically for the electronic
precision welding industry. As a mainstream SMT-specific nitrogen
purifier, it serves as the core supporting equipment for reflow
soldering systems, perfectly adapting to various lead-free reflow
soldering production lines. This system effectively addresses
common issues of insufficient gas supply purity and excessive water
and oxygen content in standard nitrogen generators, providing
stable high-purity protective nitrogen for SMT manufacturing
processes.
This SMT reflow soldering nitrogen purification equipment utilizes
mature catalytic deoxygenation and molecular sieve deep drying
purification technologies. Using industrial-grade common nitrogen
as raw material, the system removes residual oxygen through
efficient catalytic reactions, followed by multi-stage adsorption
drying treatment to deeply eliminate water vapor, impurities, and
trace gas contaminants. The HCH type equipment consistently
produces high-purity nitrogen with purity levels ≥ 99.999%,
featuring extremely low oxygen content and dew points reaching
-70°C. This performance completely eliminates common soldering
issues including PCB oxidation, virtual soldering, blackening, and
color variations, significantly improving surface mount soldering
yield rates.
The HCH type nitrogen purification equipment features an integrated
design with compact structure, minimal footprint, and
straightforward installation, making it suitable for various
factory workshop configurations. Equipped with a fully automatic
intelligent control system, the equipment achieves automatic
nitrogen-hydrogen ratio adjustment, automatic regeneration, and
real-time operational monitoring. Supporting 24-hour continuous
stable gas supply without requiring manual supervision, the system
is ideally suited for high-intensity continuous production
environments typical of SMT assembly lines.
Compared to traditional purification equipment, the HCH system
offers extended catalyst service life, stable purification
performance, low energy consumption, simple operation and
maintenance procedures, and minimal failure rates. These advantages
effectively reduce both gas and equipment maintenance costs for
enterprises. With exceptional purification efficiency and reliable
operational performance, this equipment finds widespread
application in SMT surface mount processing, precision electronic
soldering, semiconductor packaging, and related fields, serving as
core supporting equipment for enhancing reflow soldering process
quality and efficiency while stabilizing production output.
