Next-generation energy compatible! Inline type frame arrester
■ Hydrogen gas (Group 2C) compatible type - Hydrogen gas is classified as explosion group 2C, which is highly flammable and can explode with even a small ignition source, necessitating appropriate safety measures. - Compatible with gases from explosion groups 2A, 2B3, 2B, etc., other than explosion group 2C. - The screw connection type is compatible with 2A. ■ Prevents flame escape from bidirectional external ignition sources - Suppresses flame propagation during fires occurring inside and outside the plant, preventing serious secondary disasters. - The entrance and exit are designed to prevent flame escape from both directions. - Can be installed and used in both horizontal and vertical orientations. ■ Uses a clean ribbon type flame suppression element - The clean ribbon (wave-shaped structural component) consists of thin metal wave plates and flat plates of the same material stacked alternately to create gaps, with specifications determined by the gas used. ■ Complies with international standard ISO16852 - Our clean ribbon type frame arrestor is tested with the test gas specified in ISO16852. - Performance verification tests comply with ISO16852:2016. ■ New lineup of Rc1 and Rc1/2 screw connection types - Conducted "flame suppression performance tests" at our in-house testing facility. - Compatible with explosion group 2A.
