SANERGRID ERT^® technology is especially designed to mitigate the hydrocarbon pool fire risk associated with oil-filled electrical transformers. All ERT^® technology bunds and containement tanks are equipped with special single-slope suffocating slats called EXTICOV^®-CCF™ at the top of the bund. These slats have been specially designed to accelerate the passage of burning hydrocarbons into the tank, under the slats. Once the hot oils are “trapped” into the tank, the fire self-extinguishes almost instantly due to the lack of oxygen (comburant) and forbidding its quick renewal.

As the quenching and suffoctating process is very quick, the temperature rise inside the tank is slowed down, making thermal spiral acceleration which could accelerate the spread of the fire almost impossible. The fire shutter system therefore acts passively and simultaneously on 2 of the 3 components of the fire triangle, simply and effectively.

This model has been in use and tested for over 20 years, and complies with NFC 13 200 and international standards. The brand is registered with the INPI and was successfully tested by us at the CNPP (Centre National de Prévention et Protection) in 2009 and again in 2011.

Depending on the configuration of your site, ERT^® technology is available in a range of standard containment tanks and bunds, or customised products to meet your needs in terms of oil retention, space requirements, transformer support, craning, rolling, indoors or outdoors, etc.
