Electro Freeze Brand Guidelines: The 1929 Soft-Serve Maker Run From East Moline, Ali-Owned

A Bronx workshop and an East Moline repair shop.

Electro Freeze has two beginnings that later joined. The first is in New York: the company says Charles Ericson began making soft-serve ice cream machines under the Electro Freeze name in 1929, working out of the Port Morris Machine and Tool Works in the Bronx. English Wikipedia gives the same founder and year. In 1937, the company says, it introduced the Model 25 Regular and 25P machines.

The second beginning is in East Moline, Illinois. The company’s timeline says Henry Duke moved there in 1918 and worked in manufacturing, including with the Troy Laundry manufacturing company, before starting his own business repairing and making laundry equipment in 1936, the year his son Gene joined him. During the Second World War, the company says, the Dukes kept making laundry equipment and also made bronze bushings for gun turrets as a subcontractor to Packard. In 1945 Henry Duke finished a factory of his own in East Moline.

The turn came in 1946. The founders of Dairy Queen had opened their first walk-up store in neighbouring Moline, and, the company says, asked the Dukes to repair their ice cream machine and then to build ten more. H.C. Duke & Son built Dairy Queen’s first pressurized soft-serve freezer that year; an Ali Group press release of 2014 describes it as the first soft-serve freezer for quick-service restaurants. In 1960, the company says, Duke made a non-carbonated slush machine for Dairy Queen’s Mr. Misty drink.

Bastian-Blessing, the Dukes and the Ali Group.

Electro Freeze changed hands before it reached the Dukes. The company’s timeline says the twist machine it developed in 1958 first had two handles pulled together, and that in 1966 the equipment firm Bastian-Blessing bought Electro Freeze and moved it to a new plant in Paris, Illinois, having shown a swivelling Twist Cone head at the 1964 World’s Fair.

Sources give two dates for the next sale. The company’s history page says H.C. Duke & Son, led by Gene Duke, bought Electro Freeze from Bastian-Blessing in November 1970 and moved everything to East Moline, where the Dukes had moved into the building they still use in 1967; the company’s own press releases of 2013 and 2014, and English Wikipedia, give 1969.

The timeline says Gene Duke’s sons Dan and Jim took over leadership in 1989, and that in 1993 the company introduced a Mix Transfer System to cut cleaning times. In 2003 H.C. Duke & Son and Electro Freeze were bought by the Ali Group, the Italian food-equipment group, according to the company, Ali Group’s own announcements and Wikipedia. When Ali bought the American group Welbilt in 2022, the company says, Electro Freeze came to be branded under Welbilt. Its website still names the business as Electro Freeze / H.C. Duke & Son, of East Moline.

The machines it makes today cover soft serve, frozen yogurt and custard, shakes, slush and frozen cocktails, and batch freezers for ice cream, gelato and water ice. The company says it added a laser welder and a robotic welder to its manufacturing in 2024, and another warehouse in 2023.

Gelato, soft serve and the shop counter.

Ice cream machine makers sell equipment that most customers only glimpse from the other side of a counter. The trade’s visual language is stainless steel: batch freezers, the mantecatori from which fresh gelato is squeezed out, and soft-serve machines whose taps pour a single flavour or a twist of two. Wired, writing about one soft-serve machine in 2021, summed up the basic process: liquid mix fed in through a hopper and frozen in a spinning barrel. The Los Angeles Times, reporting from a gelato school near Bologna in 2010, heard instructors say that gelato is at its best as it comes out of the machine.

The finished product goes on show. The Gelato Museum Carpigiani’s account of the trade traces how the cone made gelato easy to eat in the street and how gelato moved out of tubs and into glass display cases, so that the shop counter itself became a stage for colour and texture.

Teaching is part of the pitch. Carpigiani opened a gelato school at its headquarters outside Bologna in 2003, and the Los Angeles Times found students there from more than 100 countries; Middleby describes a Technical Development Center for its Taylor brand used for research, customer demonstrations and training. Makers present their machines in working kitchens as much as in catalogues.

Trade fairs are the other stage. SIGEP World, held every January at the Rimini Expo Centre in Italy, presents itself as an international event for gelato, pastry, chocolate, coffee, bakery and pizza, with equipment and technology among its exhibitor sectors; La Repubblica reported that the first Gelato World Tour, in 2013, was organised with SIGEP. The guides that follow set out what can be checked about each maker — who founded it, who owns it and where its machines are made — and mark clearly what rests only on the company’s own word.

A cone icon added in 2013.

Electro Freeze has documented one change to its own identity. On 4 February 2013 it introduced a new logo, which it called the most dramatic change to its visual identity since 1969. The new element was an “EF Cone” icon; the company’s president said at the time that a cone image had appeared on the arch at the top of its machines in the 1930s and 1940s but had never been part of the logo. English Wikipedia’s infobox notes the same update. At the same launch the company said its equipment was sold and serviced through distributors across the United States and in 32 other countries.

Its customers have been chains as much as single shops. The company’s timeline credits it with a shake machine for chains including McDonald’s in 1956 and, in 1984, the first mix-in blender for Dairy Queen’s Blizzard, followed by the Arctic Swirl in 1985; its 2013 announcement names Sonic and Checkers and Rally’s among chains using its machines. Away from the chains, NJ.com reported in August 2016 that the Mister Softee ice cream trucks, fitted out in New Jersey, are equipped with Electro Freeze soft-serve machines.

The company also dates several of its own product steps. In 2013 it introduced the Genesis control platform; in May 2014 it launched Sweet Choice featuring Fuzionate at the National Restaurant Association Show in Chicago, which it described as the first soft-serve machine to produce nine flavours; in 2016 it released its GES platform with the pumps moved to the front of the cabinet; and in 2020 it made a pressurized flavour-blend shake machine, the GEN-83, for a large restaurant chain, which led to the GEN-85.

For a design guide, Electro Freeze shows how an equipment brand can carry its history into a single small sign — a cone taken from the top of its old machines. Compare Carpigiani, the gelato-machine maker near Bologna that the Ali Group also lists among its brands, and Taylor, another soft-serve machine maker. For this guide we use a navy, a pale wafer and a cone tan with a slab serif, an unofficial interpretation; no product or logo is reproduced.
