Using High expansion foam is an exceptionally efficient firefighting technique for large enclosed areas such as ships’ engine rooms, warehouses, packaging plants, ships’ holds, mines, chemical stores and incineration plants. The efficiency of any high expansion foam system depends upon producing well-formed, high quality foam. It must then be delivered rapidly into the risk area, against a possible back pressure that may result from the confines of the application.
Hi Expansion foam is also used to protect severe cryogenic risks such as LNG (Liquified Natural Gas) and LPG (Liquified Petroleum Gases). Foam generators designed for standard industrial applications will not have the performance requirements necessary to meet these risks. Angus Fire has developed a special LNG Fixed Turbex System to meet this extremely demanding application, where the NFPA Fire Exposure Test calls for performance to be unaffected during the 5 min pre-burn period of the test, were temperatures can exceed 1000C.
