The hydrogen generator device with adjustable capacity is a new product of this company, which has suitable performance and design for use in various purposes. By using this device, the required hydrogen is produced at the place of consumption and the storage of excess hydrogen at the place is avoided. The internal manufacturing of this product has facilitated the provision of services and quick support for this product. By using this device, hydrogen gas can be produced with a flow of 0-300 ml/min (adjustable) at the place of consumption. In addition to very high safety, this device does not contain any environmental pollutants and the technology used in its construction is considered a green technology. It should be noted that it is possible to build this device in higher hydrogen production capacities.
