Applications
Ex-Proof Hold-Open Systems in the newly built storehouse for chemicals of the University Göttingen
The fire protection doors in the chemical store were equipped with DICTATOR hold-open systems which allows to leave the doors open and not to hinder the smooth flow of procedures by closed doors. DICTATOR designed the complete hold-open systems and also installed them. >> read more
