Filtration products are an integral part of the commercial nitric acid production which utilizes anhydrous ammonia in the presence of platinum or rhodium gauze catalyst at a high temperature. Fertilizer and explosive manufacturers realize the importance of capturing precious metals used in the production process. The faster a plant can reclaim the captured material, the sooner you can return the investment to the company. As a leader in the PGN recovery process, Graver Technologies system can reduce the time from plant to refiner and back. Additionally, from air intake units to ammonia filters, mixed gas filters to weak acid filters, we are your single source for all of your filtration needs.
