Innovative technologies & strong expertise

Delstar Energie has developed a unique, fast and safe insulation removal process that is compliant with the strictest health and environmental laws. Contrary to other methods currently used to remove asbestos insulation on rotor poles and coils, the chemical baths ensure that the copper properties before and after will be exactly the same in all aspects. Our teams have designed and developed several machines to enable us to achieve outstanding results on any job such as automated brazing machines and custom winding machines.
