Plains Mechanical Services installs, services and repairs boilers for Iowa plants from Sioux City. Our team holds ASME ‘S’ and National Board ‘R’ stamps, takes emergency calls 24/7 and can bring in a Thermogenics rental boiler when your plant needs steam.
Plains Mechanical Services is the Thermogenics branch in Iowa. Jeff Reinders founded the company in Sioux City in 1994, and it joined Thermogenics in 2023 with its local team and name unchanged. We sell, install, service and repair boilers, pressure vessels, piping systems and industrial combustion equipment. As a rep for Parker Boiler and Industrial Combustion, we know that equipment well.
Our Sioux City crews work across Iowa, South Dakota, Nebraska and Minnesota. Des Moines is about 3 hours by road. Plants anywhere in Iowa call the same number, and we confirm travel timing on the call. Thermogenics backs us with parts, specialist support and rental boilers.

The Boiler and Pressure Vessel Safety program, now within the Department of Inspections, Appeals, and Licensing, issues operating certificates and permits and sets inspection requirements.
