Checking the refrigeration circuit
Regular and accurate checking of the refrigeration circuit is an essential part of ensuring the safe and efficient operation of a refrigeration system. This ensures that all components are working properly and that there are no leaks, pressure drops or contaminants affecting the refrigerant circuit. This keeps the system running efficiently and optimizes energy consumption.
The digital manifolds in use
Thanks to the large colour display and wireless connection to the probes, all important parameters are visible at a glance. The 30-minute trend curves also ensure even more reliable analysis.
With the testo 558s, the system density can be assessed easily and reliably, thanks to the clear visualization of pressure values and temperature compensation.
