Automatic DI Bank Switching and Data Acquisition Controller

Res-Kem has developed an integrated DI Bank Switching and Data Acquisition Automation Controller. The system monitors the inlet and outlet resistivity and the flow rate. At one of several alarm points, the system will send a text message to any number of email addresses and mobile devices. As part of a service agreement with Res-Kem/General Water, the system will warn Res-Kem/General Water personnel to prepare for a replacement of the soon to be exhausted bank of DI bottles.

Depending upon the system programming the bank will attempt to rinse to quality in several stages. If it does not succeed, the bank will switch to a standby bank and notify Res-Kem that the bank is exhausted fully and needs to be changed out.

The reason why Res-Kem developed this product is many people were having problems getting replacement parts and proprietary circuit boards for the excellent product called the Aquaswitch II a registered trademark of Myron L. Also, with reduced staffing at most of our customers, people do not have the time to monitor a stack light or resistivity monitor. As a result, the quality can be poorer than required potentially damaging down stream processes and products.

A200 Stager Control from Aquamatic Discontinued

Soon after we completed changes to our website, discussed in our previous blog post, a discontinuation notice was Res-Kem just received in the mail from Aquamatic about the A200 Stager Control. After March 13, 2009 the controller, also called an A200 Impluse Stager Control, will no longer be available. The reason given was "despite their lengthy time on the market, (these products) have experienced low demand and declining sales in recent years. As a result, Pentair is making the difficult decision to eliminate these lines so it may focus on growing its core Aquamatic Valve and Control business."

Possible Solution:
A potential replacement could be the 962 Stager Control series from Aquamatic. If you contact Res-Kem we can help you determine if it will work for your application and how it may need to be configured to work.

Automation and Control of Water Treatment Systems

Res-Kem receives requests for quotation and information to automate and control industrial water treatment equipment like activated carbon, water softeners, reverse osmosis systems (RO), DI, service DI, electro-deionization (EDI), continuous deionization (CDI), ultrafiltration (UF) mixed beds, sub micron filtration, etc. using electro-mechanical timer/stagers and programmable logic controllers. We can readily respond to these requests.

In addition, Res-Kem has been receiving requests for quotation and information to automate and control other water systems for:

Odor Control

Influent Clarification

Cooling Towers

Boilers

Waste Treatment

Remote & Online Monitoring

pH Neutralization

Wastewater Control

Environmental Monitoring

Environmental Sampling

Material Handling

Res-Kem is now able to offer solutions to these automation and control needs.
