A system comprising an oil and water separator for high voltage transformers

Ingenious and avant-garde, the DRH4 instantly separates oil and water resulting from transformer leaks . This oil leak recovery and management system is designed to adapt to all transformers (up to 765 kV) with insulating oil and ejects 0.0 PPM (parts per million) water into the environment. 

The DRH4 is optimized to offer added protection thanks to it’s oil-leak detection alarm which also helps to protect company assets. Using this remote alarm feature, Voltra’s customers can implement preventative procedures for maintenance of high-voltage transformers and avoid costs related to equipment breakage and failure. 

The DRH4 exceeds industry expectations by offering a solution that has numerous benefits to customers.

4th Generation Oil Recovery System
  • Captures oil, removes water, oil is contained for recovery and reuse
  • Discharches clean water to the environment
  • Keeps historical data 
  • Helps determine maintenance priorities
  • Faster, smaller, more versatile and cost effective than other oil spill management systems.

Protects our environment
