5.1.6 Check Chiller Tightness
Chillers can be shipped either with full refrigerant charge or with 1 bar dry nitrogen-holding charge.
5.1.6.1 Chiller shipped with 1 bar nitrogen-holding charge / without refrigerant:
Follow chart figure 40
– 19DV leak test procedure
To check leaks in chiller, in addition to the nitrogen gas, the chiller should be charged with helium tracer gas. Use
an electronic leak detector to check all flanges and solder joints after the chiller is pressurized. If any leak is
detected, follow the leak test procedure.
If the chiller is spring isolated, keep all springs blocked in both directions to prevent possible pipe stress and
damage during the transfer of refrigerant from vessel to vessel during the leak test process, or any other time
refrigerant is transferred. Before initial start, ensure that springs are adjusted, chiller is charged with refrigerant,
and water circuits are full with water.
