Below Ground - ECOLINE B







Enhanced Coalescing Oil Water Separators for installation inside new or to RETROFIT existing concrete or steel tanks. This series is extremely versatile in that it can be installed inside existing above or below ground round, square or rectangular tanks. Instead of shipping heavy concrete / steel tanks cross country, simply procure a standard off the shelf tank locally and connect our turnkey separator kit to the outlet pipe inside your tank. This unique solution can save operators substantial time and expense since they can now utilize an existing tank instead of having to replace it with costly new tanking systems. Separates free non-emulsified oil, hydrocarbons, diesel, gasoline, fuels, from water to below 5 parts per million (PPM) guaranteed (below 10 PPM for many types of light crude oil). Affordable small units for flow rates starting between 50 gallons per minute (GPM) to over 1,100 GPM. Permanent filter / coalescing media can be washed by hand with a hose for years of trouble free efficient use. Maintenance is conducted above ground without having to enter tank making it more affordable, quicker, cleaner and safer. Mechanical automatic shut off valve included to prevent accidental discharge in the event the unit is not maintained on a timely basis. No electrical power requirements.
