Two main principles govern research and development activities in the purpose of providing personnel and operations constantly improving safety.

Innovating – not copying

As technology leader Temet goes where no man has gone before. Solutions to problems come from listening customers, understanding gas explosion phenomenon, participating in international communities and from insights gained during product development testing. New ideas is what is pushing development and giving You the edge.

In middle of Finnish forest in secret location is located Temet´s protoshop. Here new ideas are experimented and many eliminated before advancing to more detailed testing and third party tests.

Development activities have resulted in number of patents on industrial protection as well as on military, governmental and civilian protection.

Innovation and quality in design is based on 60 year of know-how and curiosity. Besides having years of cumulative expertise on blast protection, curiosity is exercised in international communities in order to keep up with the newest in process safety and challenge views.

Always in safe

Reliability, Reliability, Reliability. As safety critical product, you need to be sure the product works as designed and promised – no room for error. It is achieved through comprehensive versatile testing utilizing open field explosion testing, shock tube testing, FEM calculation and other methods. After confidence is received, third party tests are conducted.                               

In product design, the aim is to provide full coverage of possible risk scenarios. If you want to be safe, better to be always safe.

FEM calculation conducted on HV Series Blast Damper


As one of measures in quest for reliability, products are stressed with blast impulses during R&D until they break. Welds are one the areas being studied when examining the behavior of product under loading. Product values have safety margin due to their use as safety critical product. Passive blast protection cannot fail when other safety layers do (see Layers of Protection Analysis). Functionality is wanted to be verified and quantitative risk analysis (e.g. CFD simulations) is educated guess of the reality entailing some uncertainty.

a) Mechanisms are removed from blast damper which was deformed during blast testing b) Industrial Series PV-KK blast valves after blast testing c) Cut-out for marcographic examination d) Cut-out for marcographic examination

Cut-out test pieces going to laboratory for analysis
