    Evacuating refrigeration systems

    The professional and reliable execution of an evacuation is an indispensable work step before the initial commissioning or recommissioning of a refrigeration system. This ensures that there is no moisture, foreign gases, oil and refrigerant residues in the refrigeration system before charging.

    What customers say about Testo digital manifolds

    What else I would like to say to other installers, the device really saves a lot of time, you don't have to take as much stuff with you, you don't have to do as much yourself, because the testo 557s does everything for you.

    In the past, we had to work with analogue measuring devices and needed a notepad and we needed external temperature sensors. Testo has now incorporated all of this into a single device. This makes it much easier and much quicker for us to satisfy the customer with the performance of their device.

    My first impression is very positive, a very nice, new measuring set, the purchase of which you certainly won't regret as a cooling technician. I don't think any other brand can compete.
