Explosion decoupling inside connected ductwork to protect separators
Numerous processes can create explosive dust/air mixtures inside industrial systems (i.e., dust collectors, mixing machines, fluid bed granulators, mills, etc.). If ignition sources cannot be excluded due to process conditions, these systems are often equipped with constructive explosion protection measures such as pressure relief or pressure suppression. In this instance, connected ductwork is decoupled from containers to be protected so that no flames or explosion pressure can be transferred into other areas.
The back pressure flap ProFlap prevents the transfer of explosion pressure and flames, and additional secondary explosions. The damper blade is kept open by the air flow. In the event of an explosion, the damper blade is closed by the advancing pressure front inside the ductwork.
Reliable protection against explosion pressure and explosion flames
Keller Lufttechnik developed the back pressure flap series ProFlapIII for effective explosion decoupling for most sectors of industry. The ProFlapIII is certified as a protective system according to EU Guideline 2014/34/EU (ATEX 114) and is approved for decoupling of dust explosions of organic and mineral dusts.
Keller Lufttechnik developed the ProFlap. The closed flap seals the duct much better and all types do automatically lock now. Optimization pays. Back pressure flaps must now fulfil a strict test standard (EN16447). The new proFlapIII series successfully mastered the tests. Therefore, Keller Lufttechnik has now an unique selling point for certain applications, such as e.g. for metal/aluminium.
