Clayton Industries Brand Guidelines: A 1930 Steam Cleaner, a Coil Generator and Bornem

Walter Kerrick’s invention, William Clayton Sr.’s company.

Clayton Industries dates itself to 1930 and to a product that was not a boiler at all. In the company’s telling, Walter Kerrick invented a new kind of steam cleaner, and William Clayton Sr. developed the machine and founded the company to make it. Clayton led the management team with Kerrick as chief engineer and J. E. St. Clair as secretary-treasurer, and the cleaner grew into a line of steam cleaners sold around the world. The Belgian business paper Made in, writing in September 2021, gave the founding date as 20 October 1930.

From cleaners the company moved into industrial steam. Its British arm says that in 1935 Clayton moved into a California factory that had once belonged to Thomas Edison, and that its engineers went on to develop a series of industrial steam generators built on the forced-circulation principle. That product line became the business. Industry Today, in a profile posted online in 2016, described Clayton Industries as founded in 1930 and growing from very small units into generators and fluid heaters, run from a headquarters in El Monte, California; the company now gives its world headquarters as City of Industry, California.

Clayton has stayed a family company. Its British subsidiary says the group “started life as a family business” and that the approach is unchanged. When the Belgian plant marked its sixtieth anniversary in 2021, Made in reported that John Clayton, president of the Clayton Group and the third generation of the founding family, flew in from California for the celebration. The group, which its British arm calls Clayton Steam System Solutions, says it has four main manufacturing facilities in the United States, Mexico and Europe, with subsidiaries in Britain, France, Germany, the Netherlands and Spain.

A coil instead of a drum.

Clayton’s products centre on one design. Wikipedia’s article on forced-circulation boilers describes the Clayton steam generator as having no steam drum in the usual sense. Instead, feedwater is pumped at speed through what is in effect one long coil of small steel tubes, wound inside a vertical casing, while the combustion gases pass around the tubes. Wikipedia’s article on steam generators adds that after the coil a centrifugal separator takes moisture out of the steam–water mixture, and, drawing on Clayton’s own technical guide, that the coil is built from stacked flat spiral sections rather than helical layers. Clayton itself calls its machines once-through, forced-flow steam generators and stresses quick start-up and compact size.

The range has shifted with energy policy. Industry Today described a line called SigmaFire, built in modules, with the generator, feedwater tank and other equipment mounted on rails that slide and bolt together. In May 2026, Made in reported that the group was putting its weight behind electric and hybrid steam generators combined with digital monitoring, and Clayton’s Belgian site describes services from commissioning and water treatment to remote monitoring and training.

Clayton sells to almost any plant that uses process steam. The company names manufacturers, dairies, pharmaceutical companies, beverage makers, power stations, hospitals and shipping firms among its customers, and Made in listed breweries, food producers and chemical plants among the users of the Bornem factory’s output.

Plant rooms and steel.

Industrial boiler makers sell equipment that most people never see. A steam boiler sits in a plant room behind a hospital, a brewery, a laundry or a paper mill, and the people who buy one are engineers, facility managers and contractors. So the visual language of the category is built for a technical reader: catalogues, data sheets, project case studies and trade-show stands rather than shop windows.

The most common image is the boiler itself in a clean plant room. A packaged fire-tube boiler is usually shown as a long horizontal shell, painted and insulated, with its burner on the front, a control panel at eye level and the flue rising behind it. Around it run steam headers, valves and lagged pipework, photographed under even light so that every joint reads clearly. Cutaway drawings do the explaining: a shell opened along its length to show the furnace tube and the passes of smaller tubes, or a water-tube unit drawn with its drums and banks of tubes exposed.

The second register is the factory. Makers show shells being rolled from steel plate, welders at work on tube sheets, finished units on low-loader trailers and large boilers lifted by crane on site. These pictures stress scale and fabrication skill. Many firms in the category are old, and their histories lean on heritage photographs: riveted boilers, steam-era works yards, early advertisements and the first catalogues.

The customers appear too, usually as settings rather than people: a utility’s turbine hall, a food plant with stainless pipework, a district-heating station, a hospital service yard. Colour is mostly restrained, with greys, navy, white and one strong corporate accent, and type is set in plain sans or engineering-style faces chosen to sit comfortably beside drawings and specification tables.

California, Mexico City and Bornem.

Clayton’s generators are made in more than one country. Industry Today reported that Clayton de México was founded in Mexico City in 1959 by Tomás Valladares Rodríguez as a distributor of imported equipment, and soon began building steam and hot-water generators, waste-heat and exhaust-gas boilers and fluid heaters itself, at a plant near Mexico City that the magazine put at 14,000 square metres, turning out between 190 and 220 units a year. The Mexican company told the magazine it worked through a network of 86 distributors in Mexico and Latin America, and that it also handled installation, maintenance and technical support.

In Europe the base is Bornem, in Belgium. Clayton says Clayton of Belgium was established on 31 January 1961 and has carried out European production and engineering there ever since. Made in reported in 2021 that the company was one of the first to settle along the Rijksweg there in 1961, and that the Bornem factory makes the parts for generators destined for Europe, Russia, the Middle East and Africa. In May 2026 the same paper reported that a new production and office site of more than 14,000 square metres was being built next to the existing building, so that production could continue without a break, with the old building to be demolished afterwards. The new site combines production, engineering and logistics, and Clayton’s own Belgian site presents it as a new chapter centred on electric steam generation.

For a design guide, Clayton Industries shows how an engineering company can build an identity around one distinctive piece of hardware, a family name and a long international footprint. Compare it with Spirax Sarco, a fellow steam-system specialist, and Hurst Boiler, another American family-run boiler maker. For this guide we use deep teal, ink, steam mist and coil copper with a serif, an unofficial interpretation; no product or logo is reproduced.
