Big enough to cope, small enough to care

Callens is a Belgian family firm founded in 1966. In just over half a century it has grown into a much sought-after heating and air technology partner for the process engineering industry. So far, 7,500 clients in the Benelux and France are relying on its in-house designed thermal systems using steam and thermal oil boilers, energy recovery systems, industrial air technology and/or the associated pipework.

With respect for and gratitude to the first generation, the second generation has taken the helm of the friendly family business. Supplying a quality that is top-notch, on schedule, backed by an energetic service organization that is unique in the industry, is very much part of Callens’ DNA and allows the company to provide its customers with what they expect: speed, reliability and certainty.

In 2010 and 2018, Callens took, respectively, the companies CallensVyncke and Optimum by Callens under its wings. With its technologically innovative solutions, Optimum by Callens brings industrial processes to the next level. Bespoke engineering ensures that in-house developed thermal incinerators and heat recovery systems integrate perfectly into every production process.

Big company, family values

Callens stands for trailblazing high-tech systems, with a focus on the economic and environmental interests and an unfailing concern for people’s well-being. The 200 members of the Callens family are driven by the ambition to excel themselves and raise the bar ever higher. Under the motto ‘Big enough to cope, small enough to care’, they pride themselves on a great day’s work and on watching the company’s position as market leader in the sector grow from strength to strength.
