Through the 1980s and 1990s, the solutions from KH nordtherm became widely respected due to the company’s development of its own heating pumps which were primarily used for agricultural energy solutions.
In the summer of 2007, KH nordtherm was bought by Danfoss, but due to their new strategy (Core & Clear), Danfoss chose to sell the company again in 2010. This time under the names of Klimadan and KH nordtherm. Klimadan was focused on the distributor network, while KH nordtherm focused on the consumers.

All necessary equipment is packed on a truck, ready to perform any cleaning task at very short notice. This reduces the service time to an absolute minimum, and the plant will in short time be running again. After the cleaning, the pipes will be completely clean and any residue will be gone to make the exchangers run as efficiently as possible again.
