    Jun 08, 2017 · System leak tightness on a long-term basis is critical since leakage of the cooling medium could lead to short circuits. If a water-glycol mixture is used as the refrigerant, the normal marginal leak rate is defined as 10-3 mbar·l/s. In refrigerant circuits, required leak tightness is measured by testing to a leakage rate of 10-5 mbar·l/s.
