To meet today’s need for energy conservation and integrated systems the BECSys 5 is a fully configurable controller. The standard controller is supplied as a free chlorine and pH control, with temperature display and data logging facility. The controller features offer many unique options and can be expanded to meet the client’s needs. Options include: • Through utilising a total chlorine sensor we are able to control the power output from UV units via a combined chlorine set point, thus reducing the energy consumption and prolonging lamp life.
• Ability to control the circulation pumps via a patent – pending variable frequency drive interface which allows control of the circulation pump based on the inputs and settings directly from the controller.
• Conductivity sensor to measure the total dissolved solids (TDS), automating the water make up process.
• Turbidity meter which enables filter backwashing to be based on a water quality measurement ensuring optimum performance of the filters.
