ERT-MODULO Modular extinguishing retention tank

Description

The ERT-MODULO range makes it possible to create large areas and volumes for retaining the dielectric oils in your transformers thanks to an innovative and robust assembly in 2, 3, 4, 5 or “N” modules. Each module consists of a retention tank with single-slope suffocating slats from the ERT^® range, which can be connected to the others using the SNG-Flow™ communicating vessel system for the passage of fluids between tanks.

The ERT-MODULO range is recommended for large transformers where the width of the container exceeds the European transport gauge (2500 mm). This makes it possible to create very large ERT-MODULOs to equip large electrical transformers of up to 300 T and more than 100 T of dielectric material.

The ERT-MODULO range is also used when on-site civil engineering is complicated or old, or when it is impossible to create a pit. The ERT-MODULO retention tank forms an “above ground” retention pit that replaces the traditional concrete pit, and rests on a flat, smooth, reinforced civil engineering concrete slab. This considerably reduces your structural work costs and the time it takes to bring your substations into compliance:

In just a few hours, you can use a simple concrete slab to create a retention area that complies with 4-in-1 regulations:

• Retention: minimum 100% of the volume of the dielectric, sized by our design engineers
• Extinguishing: hydrocarbon pool fires with the EXTICOV-CCF single-slope fire suffocating slats cover, which is fitted to all our range of tanks ERT^®.
• Filtration: thanks to SPI anti hydrocarbons filters for rainwater drainage with PETRO PIT 410 or PETRO PIPE PI616M2
• Protection: of operators thanks to the systematic addition of an electro-forged 30×30 anti-slip grating, or an all-welded CUBE grating capable of withstanding 500daN/m² (2 operators + back-up can), but also SANERFALL™ technology guardrails or MODESCA™ stairs or PLATABUND™ access platform.

Other standard features of the ERT-MODULO range of fire-resistant retention tanks:

• S235 steel tank, thickness 3, 4 or 5 mm; hot-dip galvanising certificate to ISO EN1461-2022.
• Inter-tank cover caps with fastening clamp; bolts for fastening the tanks together and SNG-Flow™ watertight communicating vessel wall passages with seals, washers and installation keys
• Double watertight welding on all parts of the retention tank area to ensure complete watertightness, with individual quality inspection before leaving the factory.
• The upper part of each tank is fitted with an EXTICOV CCF extinguishing system consisting of CNPP-tested suffocating slats.
• On top of each ERT-MODULO container, we design supports that allow the equipment to be easily placed on the containers. These can be fixed beams running the length or width of the modular enclosure, or adjustable beams, or beams fitted with rolling rails, or beams for shifting, or be made up of several elephant feet fitted with load distribution plates… depending on how you want to position the transformer on the enclosure: by craning, shifting or rolling.
• At the foot of the bund, two watertight wall penetrations are available to accommodate 1.5 or 2 inch ¼-turn valves, depending on the format: the first valve for emptying the bund, the second for fitting an SPI rainwaters filtration kit. In the standard version, the bund is supplied with the two wall passages closed watertight with stainless steel plugs.
• A safety siphon is always fitted to ERT-MODULO tanks. Fitted to the bottom of the tank, it allows overflowing water to be drained off without draining oil in the event of heavy rain or blockage of the filtration system.
• Lifting hooks for easy unloading and on-site installation.

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