The Herz insulated flexible hose is a 316L stainless steel braided connector for linking fan coil units and air handling units to the pipework. Each hose has female brass union nuts on both ends and comes pre-insulated, so the connection to the coil is quick to make and needs no extra lagging on site.
The flexible braided construction takes up small misalignments between pipework and the unit, and isolates the coil from vibration. The factory insulation helps prevent condensation on chilled water connections and reduces heat loss on heating circuits.
The hoses are made to pair with HERZ HerzCON valve stations. Because each HerzCON station has an outlet one size up from its inlet, the matching hose is also one size up: DN15 stations take a DN20 hose, DN20 stations a DN25 hose, DN25 stations a DN32 hose and DN32 stations a DN40 hose. Sizes run from DN15 to DN50, in 300, 400, 500, 600 and 1000mm lengths.
Part numbers follow the HERZ HBB format: HBB + length + DN size. For example, HBB60025 is a 600mm DN25 hose. 1000mm hoses use “100” for the length, so HBB10025 is a 1m DN25 hose.
