PLC Control and Modem

Walden's custom SBR units are extremely reliable and easy to operate. Despite that built-in reliability, from time to time problems do occur. Historically, an inoperative SBR unit has required an onsite visit from an expert technician. This can be a very expensive and time consuming undertaking for those package treatment plants located hundreds, or even thousands of miles from the home office.

It has been our experience that many of the problems that may occur in SBR's can be fixed within an hour. Often the fix is a simple one, like replacing a fuse or otherwise insuring electrical continuity. These kinds of problems can be cured locally, without need of an expensive technician's onsite visit, if they can be identified.

In order to keep your water treatment problem under control, Walden's SRB units are equipped with a unique remote diagnosis capability. By making use of the modem and PLC built into every Walden unit, you can connect your site to the experts at Walden for the mere cost of a phone line and the phone call. In many cases a simple phone call can save you days or weeks of down time.

When a remote diagnosis is required, a Walden technician will work from a computer in Walden's home office in Maine, querying your plant's sensors to get a history of the problem and to determine the current phase of the SBR process. In many cases a few minutes online will be all the technician needs to determine the problem and offer a solution. Even in cases where a technician visit is required, remote diagnosis can help facilitate an accurate and rapid response from Walden.
