This system consists of an operational panel, a main water tank cabinet, a chiller, a hydrogen gas detector, etc. Users may assemble the chiller to the main water tank cabinet, and then install the hydrogen gas detector above the main cabinet at a reliable position.

Charging quantity	Two channels
Hydrogen charging pressure	10~25bar
Inlet relief valve start value	200bar
Chiller (accessory)	Temperature control range 5~35℃
Hydrogen gas detector (accessory)	High concentration  sound and light alarm
Dimension	(L×W×H) 850×450×750mm

Operating environment

1、The normal operating temperature and humidity range is as follows: 

Ambient temperature	0-40℃
Relative humidity	10-95％

Note: The working medium of the accessory chiller is liquid water, so the normal operating temperature of the entire equipment should be above 0°C. In operations below freezing (-20°C and below), the chiller can be omitted, and no liquid water should be injected into the tank.

2、For safety considerations, it is prohibited to use this system in small enclosed spaces. It is required to operate in well-ventilated spaces because hydrogen leakage could pose a significant risk.Also, avoid operations near open flames. It is recommended to have portable fire extinguishing equipment such as dry powder and carbon dioxide on-site.

3、Hydrogen purity requirements for hydrogen supply equipment:

Type	Gaseous hydrogen	Bottle pressure not exceeding 150 bar
Composition	99.99％ hydrogen	Purity requirement of 99.99% or higher
Humidity	Dry gas	No special requirements
Allowable impurities	Inert gases (nitrogen, oxygen, nitrous oxide, water vapor)	＜0.01%
	Hydrocarbons	<1ppm
	Oxygen	<220ppm
	Carbon monoxide and carbon dioxide mixture	<1ppm
	Sulfides	<0.1ppm
	Ammonia	<0.05ppm
	Nitrogen oxides	<0.5ppm
