When a renewable fuels company sought to establish a new pretreatment and processing facility in Iowa, the company brought Engineering Unlimited on board for design and commissioning support.

Engineering Unlimited developed electrical designs and documentation, purchased the control equipment, and built the PLC control and motor control panels. Engineering Unlimited engineers also provided PLC and HMI programming, and worked on-site to support electrical checkout, instrumentation setup and commissioning.


The completed facility was built with enough capacity to produce up to 30 million gallons of biodiesel per year. After the facility went online, Engineering Unlimited continued to provide support through remote-based troubleshooting and simple programming modifications.
