Great Moments in Mueller History

In 1940, Paul Mueller and his partner Gordon Mann opened the Mann and Mueller Heating and Sheet Metal Works. Their first employee was Joe White, who eventually became our Executive Vice President. Joe retired in 1972, but he still stops by from time to time to visit and check in on us.

In 1943, Paul bought Gordon Mann's share of the business after Mr. Mann became ill, and the name of the business was changed to Paul Mueller Company.

1944 marked our first venture into the food processing business. We made chicken pluckers, scalders, and eviscerating equipment for a super salesman named Kent Tomlinson.

food processing equipment

We were incorporated in Missouri in 1946, and that same year, we began manufacturing dairy processing equipment for the first time: cheese vats, culture tanks, and cheese presses.

With the new product line came new business, and in 1950 we moved from Commercial Street to Phelps Street. The original building was 27,000 square feet on a three-acre lot. In Springfield, we now have approximately 1,000,000 square feet under roof on about 50 acres.

New space made room for new products, and we built our first dairy farm milk coolers in 1955. The EmBee milk coolers were built for the Meyer-Blanke Company. Paul Mueller Company's farm milk cooler has played an important role in the success and growth of our Company. Thanks to the hard work and talents of our employees, we are recognized world-wide as the producer of the industry's highest quality farm milk cooling and storage systems.

Never content with the status quo, we continue to develop our dairy farm equipment with the farmer's bottom line in mind. With more than 72,000 milk coolers in roughly 125 countries, we can safely take at least a little credit for healthy teeth and bones all over the world.

In 1960, the decision was made to discontinue our heating and sheet metal contracting activities and to concentrate on manufacturing food processing equipment.

First Milk Cooler

We became ASME® certified to build pressure vessels in 1961, an important step in our development as a major producer of stainless steel processing equipment.

In 1964, our manufacturing facilities were expanded to our current space of 1,000,000 square feet  more than double the previous size. That same year manufacturing began on beer aging and fermenting equipment in the United States.

Wine Tanks

We began building wine tanks in 1965. Since then, our beautifully crafted tanks have been installed in wineries in Mexico, Japan, and the U.S. Our wine fermenting and storage tanks can be built specifically for either red or white wine processing.

The Mueller Fre-Heater® was introduced in 1976. The Fre-Heater is an energy-saving unit that uses heat produced during the milk cooling process for dairy farm operations. Fre-Heaters are now built at our Iowa facility.

International E Star

In 1980, Mueller International Sales Corporation, which markets to 125 countries worldwide, received the U.S. Department of Commerce "E-Star" award for excellence in export.

Accu-Therm and Temp-Plate

In 1981, manufacture of our unique, patented Temp-Plate® heat transfer surface was moved to the Warren Street facility. Developed over a period of years, it improved nearly all of our products.

In 1984, Mueller acquired the license to manufacture and sell the Accu-Therm® plate heat exchanger.

In 1985, we entered the thermal energy storage market with the Avalanche ice harvester/chiller, and have since built systems with up to 1,650 tons of refrigeration capacity.

PyroPure Products

In 1987, we acquired our manufacturing facilities in Osceola, Iowa, which provided an additional 212,800 square feet of manufacturing floor space on a 50-acre plot. That same year, we purchased the water purification product line from Barnstead Industrial Products of Boston. This was the beginning of our PyroPure® line.

The very popular 401(k) retirement plan was introduced to our employees in 1989.

In 1992, we acquired the rights to manufacture and sell vapor compression stills, our present VaPure® product line.

Mueller Field Operations Logo

In 1998, Mueller Field Operations, Inc. was established to enable us to compete for larger contracts that require on-site fabrication of tanks and other equipment.

To effectively market our products in China, we applied for and were granted the China Safety Quality License in 1999.

2000, the first year of the new millennium, was our 60th anniversary.

In early 2002, we were asked to help develop a stainless steel wine barrel prototype for a prominent California winemaker, and in 2003, we began producing our all-stainless steel wine barrels.

Wine Barrels

In 2007, our ever expanding Dairy Farm Equipment division introduced the Sentry® ITM, an information technology manager that allows dairy farmers to monitor their operations from remote locations via a computer. Mueller Dairy Farm Equipment also introduced the Avalanche® chiller, a unit specifically designed for larger dairy farms.

In 2008, Paul Mueller Company acquired our long time licensee, SSP Lichtenvoorde [The Netherlands] B.V., and formed Mueller B.V. Mueller Lichtenvoorde B.V. manufactures Paul Mueller Company's dairy farm equipment products, serving beer tanks, and a full range of heat transfer and processing equipment for the international markets.

In mid-2008 Mueller Equipment and Controls (MEC) was established. MEC fabricates power transmission and distribution panels, custom control panels, machine fabrication, motion and process control equipment. MEC is also a full service machine shop that refurbishes and repairs existing equipment.

In September 2012, we completed our first tanker trailer. This unit, for the transportation of crude oil, was quickly followed by models for refined fuels, dry bulk products, and stainless steel tankers for sanitary applications.

Over the years, Paul Mueller Company has evolved from a small-scale fabricator into a global process solution provider, supplying outstanding equipment and unique solutions to the process industries with our technical expertise, innovative engineering, and manufacturing resources. We offer integrated systems, modular fabrication, field construction, plant maintenance and repair, and complete turnkey project execution. Our goals are to conform to specifications, deliver on time, provide good value, and satisfy our customers.

Mueller is committed to meeting and exceeding our customers' expectations of value by providing quality equipment and excellent service.
