More than 400 skilled specialists
The Callens Group unites all crucial disciplines in specialized teams. More than 400 skilled specialists – spread across Belgium, the Netherlands, and France – put their niche knowledge to work for tailor-made solutions on your industrial site.
Within the Callens Group, every area of expertise works together day after day. That way, we share our knowledge to the fullest and save valuable time.
For you, that means:
one point of contact throughout the entire project;
no communication breakdowns between different parties;
faster decision-making and execution;
more control over quality and planning;
an installation that is designed and built as a single whole.
Engineers – concept engineering and project management
Our engineers map out your current and future situation. Their knowledge is essential when it comes to determining the right technologies and integrating them logically into an energy-efficient installation.
By analyzing the situation at an early stage, we avoid overdimensioning, costly adjustments afterwards, and unnecessary energy losses. Our project managers then oversee the planning, the budget, and the coordination between all the teams involved, so that the step from design to execution proceeds smoothly.
Assembly technicians
What is designed on paper, our assembly technicians bring to life with their own hands. The placement of boilers, air handling units, pumping systems, and piping – in short, the entire balance of plant – is handled by the assembly crews. Thanks to this direct collaboration between engineering and assembly, the transition from design to realization runs seamlessly.
Every technician carries a wealth of training, matching certificates, and experience. This guarantees a safe process on site and a high-quality finish.
Service and maintenance technicians
Even after start-up, our specialists stay involved. A team of 120 service and maintenance technicians takes care of preventive maintenance, technical support, and rapid interventions. In doing so, they help increase the reliability of your installation, limit downtime, and extend its service life. They are available 24/7 and always close by.
Behind the scenes, buyers, prevention advisors, planners, warehouse staff, and administrative teams provide support to the project teams. This keeps every project running smoothly and ensures expertise in every phase.
Highly trained and certified
Technology, energy management, and safety standards never stand still. That is why we continuously invest in training and certification.
Our people stay up to date with new techniques, regulations, and innovations within the industrial energy sector. This guarantees a partner that doesn’t just promise quality and safety but also underpins them structurally.
