EXPRO — the name is short for Extinguish Protection — was founded in November 1987 and was the first suppression installer recognised by the Belgian insurers’ body. It publishes more of its evidence than any other firm in the Belgian register: BOSEC certificate B-9043-EX-G-6, ISO 9001:2015, VCA** valid to 2027, Flemish recognition for handling ozone-depleting substances and fluorinated gases, and public-procurement recognition number 21330 issued in March 2023. It installs IG-55 and CO2 systems, FK-5-1-12 clean agent, Ansul wet-chemical kitchen suppression and AquaMist water mist from Tubize in Walloon Brabant, running five permanent installation teams. It states plainly that it does not do detection.
