Microprocessor control of generator work modes makes it a standalone device, and it also allows to control basic and technical generator parameters, including pressure, consumption, level of water poured in the tanks, electrolyzer current, leakproofness of gas mains. All mains of generator are made of inert materials.
Both types of generators provide:
- gas purification system
- microprocessor control
- decrease of heat release and reliability improvement by means of using electrolyzer power supply with high efficiency coefficient
- protection from hydrogen pressure excess and electrolyzer current excess
- increase of service life by means of hydrogen productivity regulating
- prevention of moisture ingress to the user’s pipes by using control and water level indication.
Indication of generator main parameters on LCD display provided in both generators:
- outlet pressure
- electrolyzer current
- hydrogen consumption
Control and insertion of parameters is done by 4-button keypad. Hydrogen generators allow to reduce greatly or completely eliminate, in the majority of cases, the use of bottled gas for chromatograph provision.
В There is no hydrogen reserve in generators that can possibly momentary fill the laboratory or chromatograph, and its productivity will not allow to create an explosive concentration of gas in the room, and that increases its safety.
Electric power from single-phase network AC power with voltage from 187 to 242 V, frequency (50±1) Hz, work mode – continuous.
Bidistilled water is used for filling hydrogen generators, quality index of water must be no less than 1st grade of ISO 3696 with electric resistivity no less than 1 Ohm m/cm at 25ºC.
