The latest in Zebra Skimmers’ Muscle line of coalescers, the Muscle Flexor, features a surface venturi that redirects separated tramp oil into a coalescing cylinder. According to the company, benefits of this design include centralized, contained tramp oil storage; coolant-free discharge of tramp oil; built-in aeration that discourages bacterial growth; and a cleaner coolant surface that enables monitoring of concentration and other chemical parameters.
