When you buy a circulator, you are not buying cooling or heating power. You are buying temperature control. Case studies show empirical data so that you know before you commit to buy: the speed, practical operating range, response and abilities of a Huber product. The picture shows just such an explanation during a recent customer visit. Using the selection of case studies in the catalogue (there are over 200 on the Huber website) we could show the customer the abilities and differences between selected Huber Units.
