China Hydrogen Bromide Compressor Suppliers - High Purity, Oil-Free, Corrosion-Resistant Factory Equipment
Advantages of Hydrogen Bromide Diaphragm Compressor
-
Absolutely Oil-Free and Zero Leakage Guarantee
The unique metal diaphragm completely physically isolates the process gas from the hydraulic oil system, achieving 100% oil-free compression. The entire gas chamber adopts a static sealing structure, fundamentally eliminating the risk of hydrogen bromide gas leaking outward or external impurities penetrating inward, perfectly meeting the extremely high purity requirements of semiconductor etching and similar applications. -
Intrinsically Safe Corrosion-Resistant Platform
All flow-wetted components can be manufactured from high-grade corrosion-resistant alloys. The gas only contacts carefully selected anti-corrosion surfaces, avoiding the complex corrosion and wear issues associated with dynamic seals in reciprocating compressors. This results in long equipment life and significantly extended maintenance intervals.
Key Design Points
-
Full-Series Corrosion-Resistant Materials
All components in contact with hydrogen bromide, including the diaphragm head, cylinder head, gas valves, internal piping, and flanges, must be made of materials resistant to hydrobromic acid corrosion. SS316L stainless steel is the basic choice. For extreme conditions with high moisture content or other oxidizing impurities, evaluation and upgrading to duplex stainless steel or nickel-based alloys are necessary. All stainless steel components must ensure sufficient corrosion allowance (typically not less than 2 mm) and undergo thorough degreasing, cleaning, and passivation treatment. -
Core Diaphragm & Rupture Monitoring
The diaphragm is the core component for isolation and sealing. Materials with excellent corrosion resistance in hydrogen bromide environments and high fatigue strength, such as special alloys like Inconel 718, must be selected. A standard three-layer diaphragm structure with a diaphragm rupture alarm device is required. When the middle diaphragm ruptures, the pressure sensor immediately triggers an alarm for maintenance, while the outer diaphragm still ensures no gas leakage, providing dual safety protection. -
Integrated Safety Discharge & Monitoring
Exhaust gas containing hydrogen bromide from the safety valve must never be discharged directly into the atmosphere or a flare; it must be directed to a dedicated caustic scrubber for neutralization treatment. A fixed hydrogen bromide gas detector probe shall be integrated into the compressor skid to monitor the ambient concentration in real-time and interlock with the ventilation system. Simultaneously, continuous monitoring of cooling water flow, oil pressure, and pressures and temperatures at each stage shall be conducted, with comprehensive alarm and shutdown interlock logic configured.

Frequently Asked Questions
Hydrogen Bromide is highly toxic, corrosive, and reactive. A diaphragm compressor uses a static metal diaphragm seal that physically isolates the gas chamber from the hydraulic system, ensuring zero leakage and keeping the compressed HBr completely oil-free.
The flow-wetted parts, including the cylinder head and diaphragms, are made from high-grade corrosion-resistant materials. SS316L is the baseline, while duplex stainless steels or nickel-based alloys like Inconel 718 are selected for high-moisture or severe operating conditions.
The compressor features a standard three-layer diaphragm structure. If the middle layer ruptures, a pressure sensor immediately triggers an alarm for maintenance while the outer layers prevent gas leakage, ensuring dual safety protection.
Exhaust gas containing hydrogen bromide from the safety valve must never be discharged directly into the atmosphere. It must be piped into a dedicated caustic scrubber system to neutralize the acid gas safely.
Depending on the specific installation environment and the compressor model, both water-cooled and air-cooled options are available to maintain optimal operating temperatures.
Yes, the 100% oil-free design and static metallic sealing structure prevent any trace oil or external contamination from entering the gas stream, perfectly meeting the high-purity demands of semiconductor etching.
