China Neon Gas Compressor Factory - High-Pressure & High-Purity Neon Gas Suppliers for Industry Applications
Ultimate Gas Cleanliness
The diaphragm compressor uses a metal diaphragm to completely physically isolate the hydraulic oil from the compressed gas, achieving truly 100% oil-free compression. This core mechanism ensures that the precious neon gas is never contaminated by any hydrocarbons, lubricating oil, or particulates throughout the boosting process. Its purity can be stably maintained at an extremely high level of over 99.999%, perfectly matching demanding high-purity applications such as semiconductor manufacturing and high-precision lasers.
Superior Static Sealing
In a diaphragm compressor, the gas is completely sealed within the chamber formed by the metal diaphragm and the curved surface of the cylinder head. This structure fundamentally eliminates the dynamic sealing points found at the piston rod in traditional compressors, thus excellently preventing the leakage of valuable neon gas to the outside. This directly guarantees operational economy by avoiding the loss of rare gases, achieving a unity of high efficiency and safety.
Material Compatibility
Although neon is chemically inert and non-corrosive, to ensure ultra-high purity and long-term reliability, all gas flow-wetted components should be made of austenitic stainless steel (e.g., 304, 316L). These components must undergo strict degreasing, cleaning, and passivation before assembly to ensure that the residual surface oil and grease is below the standard (e.g., ≤300 mg/m²), thereby eliminating any potential source of contamination.
Safety Monitoring
The diaphragm is the core of isolation and sealing. A highly sensitive diaphragm rupture monitoring and alarm system must be installed. In the event of diaphragm damage, the system should immediately alarm and interlock to shut down, preventing hydraulic oil from mixing with neon. At the same time, an independent safety valve must be installed after each compression stage, with its set pressure precisely calibrated to provide reliable overpressure protection for the system.
Thermal Management
Although the adiabatic index of neon is not as extreme as that of helium, attention must still be paid to the temperature rise during compression. The cooling channels of the diaphragm cavity should be optimized during design to ensure adequate cooling, bringing the compression process closer to an isothermal process to control the discharge temperature, protect the diaphragm, and improve operating efficiency. For different operating conditions such as neon recovery or filling, variable frequency drive or precision bypass regulation functions should be integrated to achieve flexible and stable flow control.
