PTFE Orifice-Riser Distributors are non-clogging and adaptable to a wide range of flow rates.

Edlon's unique design is a combination of a pan type orifice distributor and a weir riser distributor. Flow is self-regulated by the liquid level on the pan. In the event of a sudden increase in flow rate, or if solids were to clog the orifices, the liquid level will rise, and flow will be controlled by the notches in the riser tubes. The unit can be customized to handle high turndown ratios. In addition, it is not adversely affected by increased flow rates caused by process changes. Edlon fabricates its Orifice-Riser Distributor from virgin PTFE and PFA materials, machined and assembled to guarantee mechanical durability and corrosion resistance.
