Material of Construction

The coalescer frame is designed to last the lifetime of the separator unit. The coalescer frame is built of sturdy 2” x 2” 304 or 316 structural stainless steel. The plate-holding strips are 304 stainless steel, as well. Marine aluminum and 316 stainless steel plate-holding strips are available for particular applications. The Multi-Pack can accommodate any flat plate material. Coalescer materials that have been used include: polypropylene, pvc, cpvc, acrylic, aluminum, marine aluminum, 304 & 304L stainless steel, 316 and 316L stainless steel. Other materials such as phenolic epoxies composite materials show promise, as well.

Other Designs: Most other designs utilize a shop-fabricated 1” x 1” 304 stainless steel frame or no frame system at all. The standard coalescer plates are typically polypropylene, pvc, or painted carbon steel. Plastic coalescer plates are heat sealed to form the pack and are set in the coalescer frame. Carbon steel plate coalescer plates are typically stitch welded into the carbon steel coalescer frames and are not removable for cleaning.
