Request product informationHG series technology
Thermal coupling, built for responsive hydrogen supply.
HG generators couple palladium-membrane purification, high-thermal-stability catalyst technology and aluminium-alloy casting. The catalyst and membrane operate at aligned optimum temperatures, while high heat-transfer aluminium alloy rapidly delivers combustion heat to the reformer.

From fuel to hydrogen
Efficient conversion, ready when needed.
High-thermal-stability catalyst technology and palladium-membrane purification are thermally coupled to avoid the temperature mismatch associated with conventional copper-zinc catalysts. The result is efficient, gentle conversion of methanol-water into hydrogen for downstream equipment.
Thermal coupling
Aligned catalyst and membrane temperatures support stable reforming and hydrogen purification.
Rapid heat delivery
High heat-transfer aluminium alloy moves combustion heat quickly to the reactor.
Ready in 30 seconds
Unique hot-standby operation enables rapid hydrogen generation when demand arrives.
Application fit
Hydrogen supply scaled to the job.
