Hydrogen Supply Solutions

Low-pressure metal hydride canister

Low-pressure metal hydride canisters from Heliocentris enable safe and easy intermediate storage of larger quantities of hydrogen in an extremely compact form. Low-pressure metal hydride canisters are the ideal solution especially for systems with a limited installation space.

• Storage capacity (at charge pressure of 17 bar): 60 | 250 | 760 Nl
• Output: 0.5 | 1.7 | 6 Nl/min
• Weight: 0.8 | 2.3 | 6.5 kg
• Size: ø 51x200 | ø 64x365 | ø 89x420 mm
• Charge pressure: 10 ... 17 bar
• Charge time: ca. 1 h at 20°C and active cooling

Compact storage medium

Low-pressure metal hydride canisters achieve high volumetric energy density with low canister pressure. This enables intermediate storage of larger quantities of hydrogen in a very compact form. 

For flexibility and diversity of applications

Due to different storage capacities (60, 250 and 760 Nl) and the capability of connecting several low-pressure metal hydride canisters with each other, you can implement systems with widely varying capacities.

Safe handling

Low-pressure metal hydride canisters from Heliocentris can be filled safely and easily at low pressures of 10 to 17 bar. An integrated quick coupling enables easy and safe connecting and disconnecting with absolutely no leakage of hydrogen. 

Long service life

Metal hydride canisters from Heliocentris can be refilled as often as you like; hardly any storage capacity is lost, assuming the hydrogen purity* is sufficient.

Hydrogen generator

The hydrogen generators of the HG series (HG 15 | 30 | 60) from Heliocentris enable the production of high-purity hydrogen (99.9999 % vol) for laboratory and research use, whenever you need it. They are ideal both for direct operation of fuel cell systems and for filling low-pressure metal hydride canisters.

• Hydrogen production: 15 | 30 | 60 Nl/h
• Power consumption: 160 | 300 | 530 VA
• Hydrogen purity: 6.0 (99.9999 % vol.)
• Hydrogen pressure: 0.1…10.7 bar (1…155 psi)
• Size: 230 x 355 x 410 mm (W x D x H)
• Weight (unfilled): 17.5 | 19 | 22 kg

High hydrogen purity

The hydrogen generators of the HG series are designed for continuous operation. PEM technology, in combination with an innovative gas dehydration system, achieves a hydrogen purity of 6.0 (99.9999 % vol.) – with no maintenance whatsoever.

Convenient and versatile to use

The operating controls on the unit are user-friendly and intuitive. It can be connected to a PC via the optional RS232 interface.

Due to the optimum technical configuration, the units are suitable both for trouble-free filling of Heliocentris low-pressure metal hydride canisters and for the direct supply of fuel cell systems.

High operational reliability

No hydrogen is stored in the unit. An intelligent regulator ensures that only the quantity of hydrogen is generated that is currently needed.

An integrated leak monitor stops the generation of hydrogen immediately in case of a leak.

Flexible expandability

The hydrogen capacity can be expanded by connecting up to 10 modular units. One unit is used to conveniently control the others, based on the master-slave principle.

Hydrogen Safety Package

The Hydrogen Safety Package includes a hydrogen sensor and leak test liquid for easy detection of leaks. The hydrogen sensor is equipped with a display and various acoustic and visual alarm levels to warn you in the event that the current concentration of hydrogen in the room air exceeds a specified value.
