Plenum Plus PVDF Floor Drains are used in chemical waste drainage applications such as laboratories in schools, universities, and research facilities. Plenum Plus PVDF has superior chemical resistance to many solvents, acids, bases, and halogens. It also has superior abrasion resistance, dielectric properties, and mechanical strength over a wide temperature range, making it ideal for demanding applications. There are two methods for joining. The No-Hub mechanical joint is an economical, fast, and easy method that requires only standard hand tools. No-Hub uses a stainless steel outer coupling to create tight, leak-free, and reconfigurable joints. The Rionfuse CF electrofusion joining system makes it easy to create strong joints that resist aggressive acids and chemicals. A heavy gauge wire is molded into the Rionfuse coupling, and permanent hermetically-sealed joints can be made quickly with the Rionfuser electrofusion machine.
