When your transformer contains natural ester-based fluids like ENVIRONTEMP FR3 or BIOTEMP, a transformer secondary oil containment system is still required. Although classified as biodegradable, natural ester oils still produce an oil sheen when released into the environment. Oil sheens are harmful to the natural world. As a result, the EPA Spill Prevention Control and Countermeasures (SPCC) per 40 CFR 112.7, IEEE Std. 980, and MOECC requirements in Canada require organizations with natural ester oil-filled equipment to have an oil spill response plan or a secondary oil containment system to prevent an oil spill from reaching navigable waters.
Albarrie’s EsterWeb Transformer Secondary Oil Containment System is ideal for natural ester-based fluids. These oils can be difficult to contain with polymer solidification-based systems. We’ve tailored our innovative secondary oil containment system to account for the slow gelling of these oils, ensuring their full containment. EsterWeb allows water to pass through its smart layers without accumulating, which eliminates the need for pumps or oil detection systems. If an oil leak or equipment failure occurs, the smart oleophilic (a substance with an affinity for oils and not for water) layer will congeal and seal, trapping the oil within the containment system.
