Welcome to Advance Thermotec

Advance was founded in 1919 in Milwaukee Wisconsin to erect and maintain stationary boilers throughout southeastern Wisconsin.  Since that time our mission has evolved but our focus remains in serving the power generation industry.  While we continue to perform field boiler repairs for a variety of industries from paper to great lakes shipping fleets to the area utilities, we are also experts in the fabrication of ASME pressure vessels for the power and water treatment industries.
