We are on call for our customers around the clock. This is particularly important where refrigeration and air conditioning are essential for flawless production and the storage of perishable goods, where server systems only function properly in cool rooms, or where HVAC technology in hospitals and buildings is important for people's well-being.

24 hours a day, 365 days a year

Our on-call centre is permanently staffed with experienced specialists who stay cool when things "heat up" at your end. In the event of a malfunction, we respond quickly and without fuss and take the necessary decisions - 24 hours a day, 365 days a year, of course.
