Bursting Disc Holder – Type BHS

The BHS Bursting Disc Holder is a stainless-steel mounting system engineered for the precise and secure installation of bursting discs in screw-type pipe couplings. Designed for operational efficiency, adaptability, and long-term reliability, the BHS provides a robust solution for a wide range of process environments — including stringent hygienic applications.

With high-grade materials and a surface finish below 0.8 µm Ra, the BHS holder aligns perfectly with the requirements of the pharmaceutical, biotechnology, and food processing sectors. Its high-temperature resistance up to 550 °C ensures dependable performance in challenging thermal conditions.

Key Capabilities

• Compatible with multiple pipe interfaces including Clamp, ISO-K, ISO-KF, and hygienic couplings
• Surface roughness < 0.8 µm for sanitary and aseptic environments
• Temperature resistance up to 550 °C
• Available in standard sizes DN 25 to DN 80
• Custom configurations available for bespoke system requirements
• External centering for simple, error-free installation
• Multiple screw connections enable a defined torque and repeatable assembly
• Holder remains fully reusable after disc activation

Bursting Disc Compatibility

The BHS holder supports a broad range of bursting disc technologies:

• Flat composite bursting discs
• Cambered composite discs
• Forward-acting rupture discs
• Reverse-buckling bursting discs

This flexibility allows operators to streamline inventory, standardise installation methods, and adapt to variable operating pressures or product media with ease.

Optional Burst Monitoring

The BHS holder can be fitted with integrated burst detection to provide instant feedback to process control systems:

• Inductive proximity switch mounted directly into the holder
• Membrane signal transmitter incorporated into the bursting disc assembly

Both monitoring variants deliver immediate activation signals upon disc rupture, enabling fast shutdown and reducing downstream risk.

Benefits

• Reusable holder reduces lifetime operating costs
• High chemical and temperature durability
• Fast and accurate installation via external centering
• Compatible with diverse bursting disc types and pipe standards
• Hygienic design meets pharmaceutical and food-processing requirements
• Reliable, safe installation even in demanding thermal and pressure conditions

The BHS Bursting Disc Holder delivers a future-proof, hygienic, and versatile mounting system that enhances process safety while minimising maintenance downtime.
