Refrigeration technology

Finding leaks

Leaks in a refrigeration system, such as an air conditioning system, can quickly have serious consequences. The system would no longer provide the required cooling capacity and, in the worst case scenario, the refrigeration system may even be damaged. The leak detectors from Testo can detect even the smallest leaks.
