About Us

Company History

Technology Evaluations, Inc. (TEI) was incorporated over ten years ago, when Aimtech Pty, Ltd. and AJW Consultants merged.  Tony Witheridge, the founder of TEI, is a hands-on innovator and has worked in many industries evaluating hundreds of new processes and product innovations.  TEI is valued by our clients because our solutions are practical, cost-effective and work in the field.

In response to a problem encountered by one of our clients - stuck inventory - Tony found a solution so effective that we now manufacture the TEI Fluidizer to improve fine powder discharge from bulk storage units equipped with air-slides.  The TEI Fluidizer is a significant advancement in Pneumatic Modulation Technology, and a welcome answer to stuck inventory, erratic discharge and rat hole formation for the cement and fly ash industries.

Located in Batavia, Illinois, Tony recently joined forces with Jane Graeffe Witheridge to develop the TEI Fluidizer business.  Jane has over 30 years experience in business development, acquisitions and start ups.  In addition to her management consulting work in the environmental industry, her job is to implement our equipment marketing plan and keep business on track, on time and within budget.

A Team Approach

We work with other firms and professionals when a job requires. More often though, we work with our client's team - those who know the problems best and understand where the greatest value can be added.
