Edlon”s Secure & Pure family of vessels, linings, and coatings are designed for sanitary or chemical applications. Vessels feature a one-piece, 90-mil-thick, removable Teflon PFA liner with a high-density polyethylene outer shell to eliminate possible metal-ion contamination from the container. Additional features include sidewall cutouts for liquid level monitoring, heat exchanger coils, PFA-coated mixer assemblies, spray bars, baffles, and flare-type fittings for feed line connections. The line also includes fluoropolymer coatings and glass-backed, bonded fluoropolymer liners designed to satisfy sanitary requirements. Liners are adhered using a proprietary bonding system. Liner materials include PVDF, ECTFE, Tefzel, Teflon PFA, FEP, or PTFE. Coatings and liners are capable of withstanding full vacuum conditions even under severe temperature and corrosion.
