For immersion in liquid nitrogen a period of 5 min is to short for source design with leak sizes < 1 x 10 Pa*m³/s and voids < 10 mm³; significant longer periods up to 90 min could be necessary for bubble emanating. Easily pre-check systems for leaks due to loose mechanical connections, hose leaks, evaporators and condensers without using refrigerant and venting into the atmosphere. The important points to remember when carrying out a tightness test are: A pressure of up to 10 bar g (150 psig) is usually sufficient to find leaks using a soap solution. nitrogen purging and subsequent nitrogen/helium leak testing form a critical path to the success of any project.
