Adding Value to Customers Since 1969

Since its foundation in 1969, Halton Group has grown from a small national company to a leading global business in indoor climate technology. Halton’s competitiveness is based on customer-focused products and solutions for a selected range of demanding applications. Technologically and locally focused operations together with international expansion have been the driving forces of the family-owned company.

To celebrate the first half-century of its operation in 2019, Halton published an anniversary book:

1969–1979 | Establishment of the company

The founder of Halton Group, Seppo Halttunen, had the vision of an international company with its own products, production, R&D, and a good reputation among customers. The company’s operations were based on strong customer orientation from the very beginning. In the early days, store furniture accounted for a large part of the company’s operations. This ensured the continuity of the business and laid the foundation for long-term success.

Halton initially grew in Finland, but soon began exporting. International success was first achieved in the Nordic market, with the company expanding its operations to Central Europe and beyond soon after. In 1978, Halton founded its first foreign subsidiary, Oston Ltd., which manufactured checkout counters for stores, in Canada.

Halton’s net sales grew profitably by an average of 30% a year throughout the 70s. However, the company’s future was already thought to lie in indoor air products and it began making major investments in R&D.

1980–1989 | International growth and focus on R&D

The new decade brought new ideas and markets. The North American store furniture business continued to grow. However, a new business focusing on recycling systems was launched in Finland in 1982, and the domestic store-furniture business was sold three years later.

The key factor in Halton’s international growth was probably the establishment of the first R&D center focused on indoor air products, the Halton Innovation Hub, in Kausala in 1984. This 10 million markka investment was a major risk for a company with annual net sales of 30 million markka. However, the center convinced customers of the excellent quality and functionality of Halton’s products, and the company expanded rapidly. Sales offices that had been opened in Sweden and the United States a couple of years earlier were joined by sales operations in Norway (1984), the Netherlands (1985), the United Kingdom (1987) and Denmark (1988).

1989 was an important year in many ways. Halton bought a French indoor air company, Anemotherm, and started building a new factory in Béthune. In the same year, US operations at the new production facility were expanded, and operations launched at new factories in Lahti and Heinola.

Halton received numerous accolades during the decade, the most significant of which was the Export Prize awarded by the President of the Republic of Finland in 1988.

1990–1999 | Focus on indoor air

Rapid internationalization continued. With the acquisition of Anemotherm, Halton entered the vast internal market of the European Union. Halton continued its expansion, entering Belgium in 1991 and establishing an air conditioning sales unit in Germany in 1992.

In 1996, Halton began operating in Asia by setting up a joint venture in Malaysia with a local company, Hamodal. Sales were launched in Moscow in 1997. In the same year, Halton decided to focus on indoor climate solutions, building a factory in Scottsville, Kentucky, USA. A research and development center was opened alongside the factory in the following year. The recycling business was sold and the store furniture business became an independent company. In 1999, Halton founded a sales office in Warsaw.

2000–2009 | More acquisitions and new know-how

In 2000, Halton acquired Acti-Com AS in Norway and CanVent Co. in Canada. An indoor air technology development project was launched in cooperation with the National University of Singapore (NUS) in the following year.

In 2003, Halton acquired Clairia, a leading Finnish manufacturer of filters. Halton began factory production in China in 2005. It acquired a significant competitor, Vent Master, in the same year. This acquisition strengthened Halton’s position in the UK and North American markets, in particular, complementing its expertise in the commercial kitchen sector.

In 2006, Halton strengthened its Foodservice business — which specializes in indoor air in commercial kitchens — and its position as a leader in international markets and technology, by acquiring Wimböck, a German family-owned company. This acquisition provided Halton with a strong market position in Japan.

Indoorium Oy, which offers indoor environment management solutions, joined the Halton Group in 2007.

2010-2019 | Solid growth, multiple acquisitions, and new partnerships

Halton’s Foodservice business continued to grow rapidly in Asia. The Chinese factory moved to new premises in 2010. In 2013, the company opened a new R&D center, the Halton Innovation Hub, and expanded production in Malaysia. Later, Halton also established new sales units in Indonesia, the Philippines, Thailand, Vietnam and Singapore.

In 2011, Halton acquired Current Energy Inc., a US producer of automation and remote management products and solutions. Halton entered the world of IoT solutions with this acquisition.

In 2014, Halton founded a joint venture and opened a Latin American factory with a local operator, Refrin, in Brazil. Halton also started up a joint venture, Halton-Innes, in Mexico and opened a sales office in Chile.

Halton made major investments in its factory and product development operations elsewhere during the decade: Its Hungarian factory opened in 2011, the Lahti plant extension was completed in 2015, and a new expansion of Halton’s Reit im Winkl plant in southern Germany was inaugurated a couple of years later. In 2018, the renovation of Halton’s Béthune plant in France was completed, including a local R&D center and a demonstration kitchen showcasing the company’s latest technologies.

To sharpen its focus on developing and resourcing core areas of its business, Halton sold its Clean Air filter business in 2015 and acquired Air Scrubbers, a U.S.-based company specializing in air purification.

Acquisitions continued in 2017, with Halton buying Diffus’Air, a French supplier of turnkey indoor air solutions, to complement its French operations. Miwo, a Dutch company that delivers similar overall solutions, joined Halton in 2019. In the same year, Halton became a minority shareholder in Flamgard-Calidair, a Welsh company specializing in advanced fire and shutoff dampers on the global market, and opened sales units in Kazakhstan and Kenya.

In addition to acquisitions, Halton has established strategic partnerships to promote the integration of its technologies with other leading solutions in its target environments. Halton teamed up with two business partners to introduce the InoroomTM turnkey operating theatre on the Finnish market in 2015. In 2017, the company began a strategic partnership with Welbilt, a leading manufacturer of commercial kitchen equipment. Halton continues to be open to similar partnerships in its various business areas.

As it celebrated its 50th anniversary in 2019, Halton opened further production facilities in the United States and China.

2020- | A new era

The 2020s began with good prospects of growth, but the global economy was soon engulfed by an unprecedented crisis due to the coronavirus pandemic. Like other companies, Halton had to adjust its operations to the new situation as its customers’ businesses were severely impacted. However, the company’s strong balance sheet and cash position have ensured business continuity, and even investments, during these exceptional years. In addition, Halton’s extensive international operating network and diversified markets have helped the company surmount the worst months, with for example some manufacturing units being able to support each other.

The pandemic created opportunities as well. Indoor air was highlighted in a new way. Its role as a safety factor in indoor environments and in safeguarding the continuity of indoor activities has been now more widely recognised. However, rules, regulations and practices to define and approve solutions for pandemic safe operations are emerging only slowly.

VUCA (Volatile, Uncertain, Complex, Ambiguity) driven events continued as Russia made an illegal attack to Ukraine early 2022. This triggered many supply chain related challenges regarding poor availability and high cost of materials and other resources. We have then experienced the emergence of significant inflation and high interest rates. Geopolitical tensions are on a high level. At the same time, climate crisis is impacting people’s lives significantly around the world.

Despite of the challenging operating environment, Halton is continuing to implement its defined strategy, both investing organically and through Mergers & Acquisitions. The company invested significantly during 2023-24 in its production and development capacity and improving sustainability of operations globally. Most extensive investments were made in the USA: expanding Foodservice facilities in Scottsville, Kentucky and setting up a new facility for our Marine, Energy and Infrastructure strategic business area in Greenville, South Carolina.

In September 2020, Halton acquired a controlling stake of Flamgard Calidair, the UK-based damper and fire damper designer and manufacturer. Full ownership over Flamgard was acquired in January 2023.

In August 2021, Halton strengthened significantly its Foodservice life cycle service business by acquiring Nelbud Service Group in the USA.

In January 2023, the Swedish company CRC Medical became part of Halton Group. CRC Medical operates in the Scandinavian healthcare and cleanroom sector.

From 2023 Halton separated structurally its operative business (Halton Group) and investment activities (Halton Ventures). Ventures became the parent company for Halton. It invests with a long-term view into new technologies and services enabling a more sustainable planet.

Halton will continue to develop its globally unique indoor air expertise and range of solutions and services. This will enable us to improve significantly the sustainability and economical success of our customers’ operations.
