Unitor — sistem pemadam busa
Sistem pemadam kebakaran busa tetap
Unitor fixed foam system for the separator (purifier) room, designed to SOLAS II-2 Reg. 8. Sea water from the fire main passes an inline inductor which sucks foam concentrate from a 1 m³ GRP tank and injects it at 6 % into the water line; six spray nozzles cover the room. Because foam concentrate is corrosive, a flushing line between the water and foam lines is used after every discharge. The file holds the calculation sheet, material specification, drawings, data sheets, technical description, installation and filling procedure and the operating instruction.
