Fire containment tank with suffocating slats for electrical transformers exceeding transport gauges
The ERT® MODULO range is made up of a number of made-to-measure fireproof retention tanks that can be assembled in modules. SANERGRID®‘s ERT-MODULO range enables you to meet all the regulatory and technical requirements for fire and hydrocarbon retention for your large high-voltage power transformers, without incurring increased transport costs.
Description
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.

Use and maintenance
Before installing the tank:
- Make sure that the ground surface is smooth, flat, clean and, above all, large enough to take the weight of the transformer and ERT® -MODULO tank.
- Check that the positioning of the load pick-ups from the floor to the tray is appropriate, aligned and correctly dimensioned.
- If the tanks are stored outside, they must be emptied regularly, and not handled with water inside.
Installing the tank:
The tank must be unloaded using suitable handling equipment.
Installation by crane :
Place the transformer on the supports provided. Avoid vertical acceleration or transverse shearing.
Installation by rolling or shifting :
In the event of handling by rolling the transformer onto the tank or shifting the transformer from the lorry onto the tank, please consult us beforehand or refer to the SANER-Rail, SANER-Grantex and Rippage options.
Maintenance:
Regular visual inspection of the equipment should cover the following points:
- Installation of suffocating slats: no overlaps or missing slats, presence of CCF-STOP™, maintenance slat lockout screw.
- Tightness at wall penetrations, accessories and/or plugs correctly screwed in.
- Integrity of the tank walls, no deformation or damage (knocks, impacts, rust, etc.).
- State of ageing of the hot-dip galvanising protective layer and potential touch-ups.
- Check that rainwaters are flowing properly through the filters: if they are clogged, clean the pre-filters, or change the filters if they are saturated or have exceeded their recommended service life.
- Tightness and ageing condition of SNG-Flow™ communicating fluid system seals.
- The frequency of these checks depends on the constraints of each site, depending on its degree of corrosion, dirtiness, presence of organic matter, etc.
Refer to the user manual for further details.
Failure to comply with good practice in use and failure to deal with anomalies and defects in the field are the responsibility of the owner of the equipment.
