Explore the timeline that led to our founding nearly four decades ago. We will review how primary separation has been handled historically, and what Mercer does better in coalescer design
Companies disliked enhanced gravity oil water separators due to the baby-sitting they required.  The chronic fouling and clogging caused by sludge accumulation forced operators to constantly attempt to clean, and inevitably replace, coalescer packs. This bled OPEX budgets dry, and then compromised uptime. So, we decided to build a better product.
At the heart of the solution is our Multi-Pack™ removable plate coalescer, a patented system utilizing flat parallel-plate coalescer modules with removable and adjustable plates. Mercer created dedicated zero turbulence chambers "Chimney Zones™" for solids removal and oil extraction. We have solved the problem through our enhanced design.

Mercer International has designed a solution that combines the highest possible efficiency with the lowest practical maintenance.
At the heart of this solution is Mercer’s Multi-Pack™ removable plate coalescer, a patented system utilizing flat parallel-plate coalescer modules with removable and adjustable plates. The most important evolution in the oil water separation arena came when Mercer created dedicated zero turbulence chambers "Chimney Zones™" solids removal and oil extraction. Along with several important design innovations, Mercer’s ability to remove solids from the process flow, has led to  Mercer International's reputation for being the highest performance oil/water separator on the market.
Flat Plate Herring-Bone Design (55 degree angle)

The Multi-Pack™coalescer utilizes time-honored flat parallel plates set at a steep 55 degree angle. The smooth flat plates and cross-flow design help make this the most non-plugging design that industry has to offer. Utilizing this "Short Plate Width" design concept, coalescer plate gaps can be tighter with less plugging than traditional coalescer plate designs.

Chimney Zones™

The Multi-Pack™design offers an independent collection chamber within the coalescer for both oil and solids. As solids fall off the top of the impingement plates (or as oil droplets coalesce and rise up and out of the coalescer plates) they enter a “zero velocity” baffled Chimney Zone.  Keeping solids and oils separator reduces sludge and pre-mature fouling.

Field Adjustable Removable Plates

Plates within the coalescer are completely removable from the coalescer frame and the plate spacing is therefore able to be adjusted to multiple plate-gap settings on site. This patented feature lets the operator easily field adjust the coalescer to obtain optimal results.

Ease of Cleaning

Mercer's flat-plate herring-bone design is simply the industry's easiest coalescer to clean. The Multi-Pack™ offers 5X longer uptimes between required cleanings. Mercer has also eliminated replacement costs for internal components or coalescing media, making it the most cost-effective long-term solution.

Inlet/Outlet Flow Distribution Baffles

Mercer is one of the very few separator manufacturers that continues to provide efficient, two-stage distribution baffles. Our two-stage distribution baffle system is designed to assure evenly dispersed flow over the entire entry area of the coalescer — offering superior results within the coalescer.
