Choosing between Active or Passive conversion?
Passive conversion is conversion for Category 2 (Zone 1) that is more or less inferior in terms of quality depending on the manufacturer of the components. This can be costly in terms of acquisition and maintenance.
Active conversion associates a combustible vapour and gas detection system with protection for Zone 2.
It allows cheaper types of protection to be used, and offers the operator greater safety of use, even in the event of poor maintenance.
