Last week, a triple industrial water softener designed and manufactured by Res-Kem was started up in a Cambridge, Massachusetts steam plant. The softener system has an Allen Bradley PLC and PanelView 600 HMI for controlling the automated running and regeneration of the three softeners.
Each of the 48 inch diameter x 72 inch straight-side vessels holds 37 cubic feet of cation ion exchange resin. Careful coordination between A&E firm designing the entire plant and Res-Kem yielded a project that fit into the space and time allotted. The engineer responsible for starting up the entire steam plant stated that the Res-Kem triple water softener was the "best ion exchange system I have ever started up with a great design and excellent construction." The softeners are used to provide makeup to the steam plant.
About the Steam Plant and Network:
This steam plant supplies a steam network near Harvard University and the Massachusetts Institute of Technology (MIT). The steam network supplies process steam to global leaders in biotechnology and pharmaceuticals. The steam network used heavy fuel oil-fired boilers. The new plant now uses new gas-fired steam heating plant with a rated capacity of 110 tons per hour. The new facility will supply 150,000 tons of steam a year to its industrial customers and property owners in the Cambridge region.
