Last week, we shipped two custom water softeners. The customer was using the softeners to treat the water feeding plant safety showers. Res-Kem has the flexibility to take our standard industrial water softener designs and modify them to meet a specific customer's requirements for virtually the same cost as our standard systems.
The plant has strict explosion-proof requirements. Even with the multitude of standard designs Res-Kem has using Fleck, Autotrol, Aquamatic, and Bray valves and Aquamatic electro-mechanical or Allen Bradley controls, we collectively determined the cost to accomplish an automatic, explosion-proof design was too great for the application.
So, each system is a single tank unit with manual regeneration. The face piping was Schedule 80 PVC. The valves were true union ball valves. Polyethylene lined composite fiberglass tanks with laminate glass exterior, 150 psi ASME code. Also, the customer requested a pressure relief valve for over pressure protection.
