A horizontal, custom fabricated tank that stores foam concentrate for inline inductors and balanced pressure proportioning systems. It is built in stainless steel 304 or 316, or in carbon steel with FRP lining.
A pressure rated tank with a nylon reinforced Buna-N rubber bladder and a proportioner pre-piped on to it, used widely in low expansion foam systems. It can be supplied UL Listed, FM Approved or CE marked when specified.
One vertical or horizontal bladder tank acts as the central foam concentrate store for several proportioning lines, each running to its own hazard zone. Each line works as an independent proportioning system with its own foam concentrate control valve.
Two bladder tanks mounted on one skid, the first as the operating tank and the second as a standby reserve. Available as vertical or horizontal units.
A foam bladder tank supplied with the proportioner and a deluge valve already piped on to it. The bladder tank, proportioner and deluge valve are UL Listed.
A hydraulically controlled stainless steel valve for bladder tank and inline balanced pressure systems that opens by itself once water supply is established. Model CV is FM Approved as part of HD's foam bladder tank proportioning system.
An air aspirating foam discharge outlet for foam-water deluge systems, in upright and pendent versions.
Low expansion foam branch pipes that draw in foam concentrate themselves at a fixed 3% or 6% through a pick-up tube, in aluminium or stainless steel, straight or dome pattern.
Standard low expansion foam branch pipes without built in induction, for use with premix foam solution, in aluminium or stainless steel.
