The STONEQUENCH™ fire-suffocating range is used under electrical transformers in the concrete pit.

Our STONEQUENCH™ fire-resistant covers are specifically designed to accelerate the passage of burning hydrocarbons into the transformer’s concrete pit. Once the hot oils are “trapped” underneath, the fire self-extinguishes almost instantly due to the lack of oxygen. The STONEQUENCH™ range replaces the stones and pebbles under the transformer, providing a clean, easy-to-maintain, and non-slip handling surface, reducing the risk of falls for operators.

Our fire-resistant covers for transformers are regularly tested in various independent laboratories.
