PURITY METAL DIAPHRAGM COMPRESSORS FOR ULTRA-CLEAN AND SAFE COMPRESSION

sera metal diaphragm compressors compress sensitive and valuable gases completely contamination-free.
For applications in microelectronics, semiconductor technology, and doping technology, metal diaphragm compressors are the best choice.

APPLICATION AREAS
• Gas bottle filling and transfer systems
• Production of special gas mixtures
• Recycling of noble gases
• Gas shielding for surface treatment processes
• Nitrogen compressors for butyl production
• Hydrogen refueling stations
• Airbag inflator gas filling
• Natural gas filling in air separation plants
• Power-to-gas compressor systems
• Experimental and research facilities

 

ADVANTAGES AT A GLANCE
• Hermetically sealed to the outside
• Compression of toxic and explosive gases
• Completely lubricant-free compression
• No contamination from piston rings and gland packings • High corrosion resistance
• No need for purging and blocking gas devices
• Starting under pressure

"Due to the near-total absence of leakage to the outside, highly critical gases for humans and the environment can be compressed without concern. Therefore, sera metal diaphragm compressors are often used in applications involving toxic gases.

Depending on the requirements and the nature of the medium, various material qualities are used for components that come into contact with the gas. This ensures high corrosion resistance and long lifetimes of the gas-contacting parts."

STRUCTURE AND FUNCTION

A metallic sandwich diaphragm clamped with static seals is located between the valve head and the piston housing upper part. It hermetically separates the gas chamber from the oil-lubricated drive. Contamination of the medium by lubricants and particles is thus completely avoided. Due to this design, sera metal diaphragm compressors are also hermetically sealed to the outside, allowing for the safe compression of toxic and explosive gases.

The oscillating motion of the clamped diaphragm cyclically enlarges and reduces the gas chamber. Gas drawn in through the intake valve is compressed in this manner and expelled through the discharge valve. The diaphragm's vibration is triggered by an oil cushion, which is cyclically pressurized by a piston driven by a crank mechanism.

sera metal diaphragm compressors comply with the Machinery Directive, the ATEX Directive, and the Pressure Equipment Directive of the European Union as standard.
