Explosion relief panels are protection devices intended for protection of industrial equipment with explosion danger. RSBP equipment for explosion relief is a perfect solution to lower this risk and eliminate losses that follow such explosions.


- High effectivity and reliability

- Long service life

- Resistivity against abrasion, mechanical particle impacts and weather conditions

- Simple installation, exchange and easy availability of spare parts

- Variable safe opening pressure

- Variable panel and auxiliary equipment sizes

- Economically advantageous solution


Under normal operating conditions the equipment relief opening is covered by an explosion relief panel. If an operational pressure is exceeded inside of the equipment, a panel on its surface opens and relieves pressure from the endangered area. The technology equipment is thus exposed to smaller pressure than is its pressure resistance, and therefore it will not be destroyed.


- Domed three layer panel with PTFE isolation

- For equipment with operational temperature of up to 240 °C

- High underpressure resistance

- Stainless steel

- Suitable also for equipment with pressure pulses

- SU – Domed three layer panel with PTFE isolation

- EN 14797


- One layer construction for equipment with operational temperature of up to 100 °C

- Three layer construction with high underpressure resistance and PTFE insulation for operational temperatures of up to 240°C

- Stainless steel

- Suitable also for equipment with pressure pulses

- SU – Domed three layer panel with PTFE isolation

- D – Domed one layer panel


- Suitable for applications with low operational pressure (up to 50 % of safety opening pressure)

- For equipment with operational temperature of up to 100 °C

- Possibility of frameless installation

- Stainless steel

- Economical solution

- F–Flat panel


FLEX guarantees explosion relief in enclosed or internal spaces without propagation of flame, pressure and heat to near surroundings, therefore the equipment and technologies that are located in hard to access spaces can be protected by the flameless explosion relief without increased costs for building modifications that are usually related to installation of classical explosion relief equipment.


- Effective arrest of flame and heat and provision of a safe zone for equipment, buildings and movement of personnel

- Effective catchment of dust – no pollution of the technology or the surroundings

- Stainless steel design suitable for food and pharmaceutical industries

- High effectivity and reliability of the system

- Simple installation and maintenance-free operation

- Elimination of high costs for building modifications

- Economically advantageous solution


Explosion relief and prevention of explosion propagation into a free space are two basic functions of the system.

The relief membrane opens due to fast increasing pressure and the equipment absorbs flame, burning dust and gases. As opposed to a classical explosion relief the FLEX system is capable to absorb these undesirable effects thanks to its construction.

The explosion relief can achieve temperatures up to 1 500 °C. During explosion relief with the FLEX flameless equipment the temperature is lowered, thanks to its design, to such temperature that is not dangerous for surrounding equipment and for work and movement of personnel.
