Description
High back pressure generators (or HBPG) are designed to produce expanded foam that is delivered into a cone roof storage tank containing hydrocarbon fuels only by the subsurface foam injection method.
Subsurface foam injection is not recommended for any floating roof tank. The HBPG is also not suitable for use on tanks with alcohols or polar solvent type liquids.
Typically installed on the outside of the dike area surrounding the storage tanks. Recommended minimum inlet pressure is 100 psi (6.9 bar). The HBPG can discharge foam against a back pressure as high as 25% of the HBPG inlet pressure. Higher back pressures up to 40% can be provided on request.
Option: pressure gauge (0-300 psi range) can be provided on the inlet side of the HBPG on request.
