Hazardous Location Power Supply

Hazardous Location AC and DC Power Supplies

Added Benefits of Dry, Water or Oil Filled Rectifiers and Transformers Supplied by Neeltran – Robust and Reliable Power to run your 24/7 processes.

Neeltran, designs and builds its own rectifier-transformers and rectifiers. This ability allows us to understand the extreme duty a hazardous location power supply has to perform in extreme environments. This gives our designers the experience to design the highest quality units available. Applications for for chlorine, bleach or cathodic protection power supply, oil processing or other chemical dc power supplies can be manufactured by our team.

Neeltran possesses multi-industry, engineering, and manufacturing experience that helps us to be flexible and design products that meet your specific technical and safety requirements.

For the Hazardous market we can design the rectifier to be installed inside the same tank of the transformer. Control cabinet and fuses are positioned in a separate explosion proof box, for easy maintenance and control. Typical uses are for chlorine, chlorate, cathodic protection, impressed current cathodic protection power supply, bleach and any other processes that need hazardous location DC and AC supplies. Whether on an oil rig, oil refinery or any other hazardous location we can build to any standard. We an provide water, oil or air cooled utilizing various certified techniques.
