Working PressureThe range in which the cooler is designed to operate (above atmospheric pressure). The word "dynamic" implies that the pressure can fluctuate between the limits.
Pressure Pulsation EnduranceHow many times the cooler can withstand pressurizaton between a lower and an upper limit. The Herz number indicates the frequency of pulsations per second.
Max PressureThe maximum operating pressure.
Burst PressureThe maximum pressure the cooler can withstand before bursting.
Pressure TestThe pressure the cooler is exposed to after brazing to ensure brazing joint integrity.
Leak testThe pressure level the cooler is tested at for leaks after the pressure test.
Working TemperatureThe temperature range the cooler is designed to operate within. Operating temperatures outside of the defined range will negatively affect the strength and durability of the cooler.
Corrosion EnduranceHow long the cooler can withstand a salt spray test before starting to leak. The test simulates the expected lifetime exposure of a typical vehicle to a mixture of water and road salts.
Inner CleanlinessThe maximum amount of particles the cooler is expected to contain.
General Dimensional TolerancesThe standard to which the cooler conforms regarding dimensions specified on the technical drawing.
MaterialThe material the cooler is made of.
Max Connection Tightening TorqueThe maximum torque allowed when tightening the connection on the cooler.
