Orival, Inc.’s filters protect heat exchangers and prevent clogging of nozzles, tubes and other narrow passages by removing dirt particles of any specific gravity down to micron size, from once-through and recirculating cooling water systems. Line-pressure powered, the filters self-clean without external power, do not interrupt system flow and install easily in any position. Available for systems with capacities from 10 to 12,000 gpm (37.85 to 45,424.94 liters per minute). http://www.orival.com, filters@orival.com
