Checking heat exchangers for leaks for the dairy industry
< 30 microns
> 30 microns
A non-flammable and non-toxic gas mixture is used, which does not contaminate the heat exchanger. The N2H2 gas test is suitable for the dairy industry. The methodology eliminates media overflow and dilution of the refrigerant, and minimises user error.
The dye or hydraulic test requires water, increasing its consumption for purposes unrelated to finished product manufacture. Gas testing is energy efficient.
Highly sensitive equipment does most of the work. The labour required by the operating staff is reduced by up to 95%, as no disassembly of the equipment is required.
