The 1940s 

In 1940, Paul Mueller and his partner Gordon Mann opened Mann and Mueller Heating and Sheet Metal Works. Their first employee was Joe White, who eventually became our Executive Vice President. 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. 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.

The 1950s 

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. 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 worldwide 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.

The 1960s 

In 1960, the decision was made to discontinue our heating and sheet metal contracting activities and to concentrate on manufacturing food processing equipment. 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. 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 1970s

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 to generate hot water. Fre-Heaters are now built at our Iowa facility.

The 1980s 

In 1981, manufacture of our 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, Paul Mueller Company acquired the license to manufacture and sell the Accu-Therm® plate heat exchanger. 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 1990s 

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

The 2000s 

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. In 2007, our ever expanding Dairy Farm Equipment product line 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 Model “LSA” 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.

The 2010s 

In August 2011, David Moore became President and CEO of Paul Mueller Company. In 2014, we gathered Dairy Farm Equipment dealers for a conference at the beautiful Big Cedar Lodge to celebrate the product line’s 60th anniversary (in 2015) and unveiled three new innovative products: the Avalanche® modular HiPerForm® chiller, the digital E-Star® refrigeration unit, and a new corrugated silo. As we entered 2015, plans were being made to celebrate Mr. Paul Mueller’s 100th birthday. But on the afternoon of January 19, Mr. Mueller passed away at his home in Springfield, Missouri. Instead of celebrating his birthday, we had a milestone moment to celebrate his life, legacy, and the deep impact he made on the everyday life and culture of the company he founded 75 years ago.
