KJH-300 High Purity Hydrogen Gas Generator
Introduction
The KJH-300 is an easy-to-use hydrogen gas generator that provides high-purity gas with a stable output flow. It can replace traditional high-pressure gas cylinders and can be operated individually or simultaneously. It supports both continuous and intermittent operation without reducing gas purity. The unit is safe, reliable, and equipped with multiple protection devices.
Function
1. Utilizes electrolytic separation to extract hydrogen and oxygen from water, consuming only water and electricity to improve hydrogen purity.
2. Features photoelectric pressure control, over-liquid protection, and produces gas on demand under low pressure. It includes a minimum hydrogen saving valve for safety and stability. An efficient temperature control system ensures continuous operation during peak loads.
3. Includes a visible drying chamber for easy access and a prepositive deflation valve that removes pressure from the tube without discharging it. This makes maintenance and overhaul very convenient.
