Saving Lives with TIC/CBRN & Blast Protection for Explosive Industrial Environments

Temet is a world leader in blast protection and toxic industrial chemicals (TIC) and chemical, biological, radiological and nuclear (CBRN) filtration systems for protecting both people and equipment in industrial facilities.


In industrial applications, the threat of explosions and the need for shelter equipment is often overlooked. However, adequate protection can prevent the escalation of a minor explosion into a catastrophic event.

A safe industrial facility must protect its employees, equipment, as well as its functionality and continuity from any extreme circumstances. A clear example is the need to protect the backup generator in a nuclear power plant, but an often forgotten example is the control room and its operators, which need to remain safe and functional.

Temet is a world leader in blast protection and TIC / CBRN filtration systems for protecting both people and equipment in industrial facilities, ensuring the facility functionality and safety. Many of the company’s advanced and cost-effective blast protection solutions are installed in industrial facilities worldwide.

Temet’s solutions for the industrial sector have naturally emerged from decades of being a world leader in blast and CBRN protection for critical infrastructures, Civil Defense shelters and command centres. These solutions and expertise were customised to best fit the industrial sector needs and are tested and certified to the highest industrial standards and surpassing even the stringent Nuclear requirements.

Customisation projects are welcomed.

Blast Protection Valves and Dampers

Temet provides the most advanced solutions designed for blast scenarios, whether caused by fire, gas or man-made explosions.

Our large variety of valves and dampers can be also customised perfectly for your specific needs.

Our range of products includes Blast Dampers (HV Dampers), Blast Valves (PV-KK and many others), High-Temperature Blast Valves, Over-pressure Valves, Closing Valves (Gas-tight Shut-off Valves), Cable Transmission sleeves and others in many sizes and blast protection ranging from one to 100 bar.

The main two models are the HV Damper and the PV-KK blast valves.

The HV Blast Damper

The HV Blast Damper is a single-acting blast damper, meaning that when HV Damper is at its normal position (open for airflow), it will be closed immediately when in contact with a blast wave and will remain closed.

The PV-KK Blast valve

The PV-KK Blast valve is a double-acting blast valve, meaning that when the blast hit the valve it will close to withstand the blast waves (both incident and reflected pressures) and will return to its open position to allow continuous airflow.

Our products hold the required standards and certification to satisfy even the more severe requirements and are available in hot-dip galvanised versions and the stainless steel version for corrosive environments.
