About Us

At Allan ICS we are passionate about our work, building and/or designing common sense solutions for the control system needs you may have. We have a reputation for being a customer oriented and responsive company—anytime, day or night.

We have expertise in the following industries – Water/Wastewater, industrial controls, and system maintenance.

The success of the projects we work on, in addition to the pride we take in our work goes back to 1925 when William Allan started Allan Engineering Co. selling and servicing water/wastewater treatment equipment. In 1969 the Instrumentation and Controls group was formed with the help of our own Dennis Rintelman.

In 2004 Ted Zess split the Instrumentation and Controls group from Allan Engineering Co., and formed a new company—Allan Integrated Control Systems, Inc., as we are known today. Ann Zess entered the business in September 2004 in order to oversee day-to-day management of the business.

In 2007, we moved to a much larger location to better meet customers’ needs. The 5200 square foot facility, located in East Troy, Wisconsin, has been extensively remodeled and expanded, including substantial shop space for assembly and testing and a large room wired for systems set-up and training. We also have a location in Chicago that we use for work in the Chicago area.

Please feel free to meet our team.
