Market orientation

From the start of its operations, Calor doo has worked intensively on defining the market orientation aiming to achieve high-visibility of the company. For the past few years, despite very strong competition, the company has managed to retain its position in the market primarily due to high quality of its services which is also the main motto of our business.


Since 2008, CALOR doo has been cooperating with German company MENERGA - system air, which independently develops and produces important components and it is primarily focused on the use of technology for energy saving purposes. We have successfully cooperated on all projects that MENERGA conducted in Serbia.
