ERT-W Extinguishing retention tank with width-adjustable beams

Description

Description of the ERT-W standard range:

• S235 steel tank, thickness 3, 4 or 5 mm; hot-dip galvanising certificate to ISO EN1461-2022.
• Double sealed welds on all parts of the retention zones to guarantee a completely watertight tank, with individual quality inspection before leaving the factory.
• The upper part of each tank is fitted with an EXTICOV CCF fire extinguishing system consisting of CNPP-tested fire shutters.
• A set of 2 support beams is fitted widthways above each ERT-W tray, making it easy to place the equipment on the trays. The support beams are adjustable: their ideal position corresponds to the ECODESIGN standard; they can however be moved forward or backwards by one notch in relation to this standard. They are fastened to oblong-hole plates using 4 HM10x30 bolts with stainless steel “nylstop” locknuts and wide washers (LL) (supplied).
• The maximum weight of the transformer on the ERT^® W tray is calculated according to the NFC 51.51 standard centre-to-centre distance.
• At the foot of the bund, two watertight wall penetrations are available to accommodate 1.5-inch ¼-turn valves: the first valve to allow the bund to be drained, and the second to fit an SPI^® PETRO PIT rainwater filtration kit. In the standard version, the tank is supplied with the two wall passages sealed with stainless steel plugs.
• A safety siphon is always fitted to ERT-W tanks. Fitted to the bottom of the tank, it allows overflowing water to be drained away without draining oil in the event of heavy rain or blockage of the filtration system.

The ERT^® W containers guarantee a service life in indoor and outdoor conditions similar to that of the electrical transformer or other machine they are fitted with.
