HTECH Supply CO2 fire extinguishers were originally developed to deal with liquid fires such as burning petrol. The inert CO2 gas excludes oxygen from the surface of the liquid fire and stops the fire. These days our CO2 fire extinguishers are mainly used on electrical fires in modern offices, as the CO2 does not leave any residue and does not damage computers, although the cold temperature and the electrostatic shock from the CO2 gas can damage very sensitive electronic equipment. HTECH offer installation and commissioning of your CO2 extinguishers as well. Our BAFE certified engineers will visit you to do all the work. We also offer the servicing of all your extinguishers.
