Pressure Testing
Hi Friends ,
To ensure that there is no further leakage in the chiller , we do pressure testing with Nitrogen.
Firstly, for how much time we should stand this pressure to ensure that there is no further leakage ?
Secondly , how much pressure should be given to the chiller working on R134a and R22 (High limits of pressure are mentioned on the chiller by the manufacturer)
