Fluid Filtration Specialists

The Technical Division at Open Loop Energy has implemented many filtration solutions for users of diesel fuels and lubricants to ensure that the equipment using the fluids for production is kept running reliably.

As cleaner diesel technology advances, the manufactures of fuel system components are requiring much cleaner fuel to operate with. So with this new technology, Open Loop Energy has been helping customers address the problems with receiving ,storing, and delivering clean fuel to the more sensitive equipment by using Donaldson Clean Fuel & Lubricant products. This product is customizable to meet the needs of all users and is designed specifically to provide a single pass filtration system to meet OEM requirements.

Open Loop Energy has also implemented easy-to-service filtration systems for maintenance shops and process lubrication equipment. This equipment provides filtration for large mills, crushers, and gear boxes found in the mining industry. Maintenance shops outfitted with the latest filtration technology can now deliver clean lubricants to all the equipment for superior reliability.

Mobile Fluid Purification Service

Open Loop Energy provides on site fluid filtration. Fully equipped trucks go on site to “Kidney Loop” hydraulic systems on large mining equipment. High volume pumps and quick disconnects can clean the equipment’s oil in a minimal amount of time without the machine running. On board particle counters monitor the fluid cleaning process and provide results in ISO Standards for customer review.

Filtration Carts

Our company designs and fabricates custom oil filtration carts for use in maintenance shops. These portable filtration carts “kidney loop” the oils to meet manufactures ISO requirements. Carts can be rolled, forklifted, or crane lifted for versatility. On board heaters are installed to facilitate the filtration process.
