The SorbWeb™ Plus DRH4 Synergy
If you have oil-filled transformers, the law requires you to have a spill prevention plan in place, up to and including a secondary containment system to protect the environment and prevent oil from reaching navigable waters. Albarrie and Voltra Technology have partnered up to provide the power industry with a revolutionary above-grade containment system using a combination of Voltra’s oil-leak management system and Albarrie’s oil reactive membranes typically used in the SorbWeb™ Plus system. This comprehensive and...
