Big company, family values
Callens is a Belgian family firm, founded in 1966. In just over half a century we have grown into a much sought-after heating and air technology partner for the process engineering industry. With respect for and gratitude to the first generation, the second generation now stands at the helm of our friendly family business.
Delivering a quality that is top-notch, on schedule, backed by an energetic service organisation that is unique in our industry, is very much part of our DNA and allows us to provide our customers with what they expect from us: speed, reliability and certainty!
