Start with the hazard. CO2 is chosen where a clean, residue free agent is needed, such as live electrical equipment, electronics and precision machinery, because nothing has to be cleaned up after discharge.
Match capacity to the size of the risk. Portable 2, 3 and 4.5 Kg units cover panels and small rooms and can be wall mounted near the hazard. Trolley units of 6.5 Kg and 9 Kg suit medium industrial electrical risks, with the 9 Kg giving longer discharge than the 6.5 Kg. The 22.5 Kg twin cylinder trolley is for large risks such as substations and transformer yards.
Check compliance needs. All Savemax CO2 models listed here are BIS/ISI marked, CPWD approved and Euro certified, which matters for government and institutional tenders.
Plan refilling and servicing from day one. FPS supplies, installs, refills and maintains these extinguishers in Bhopal and across Madhya Pradesh, so a single agency can handle the full life of the unit.
