Pressure Cycle Test

For thermal management in vehicles, cooling and heating systems are essential: they protect against overheating and ensure comfort. To facilitate and accelerate lifetime testing, Poppe + Potthoff Maschinenbau has developed a special system. It simulates the driving operation for the test specimen through freely programmable temperature, flow rate, and pressure changes in sinusoidal and trapezoidal forms. Mobility requires reliable cooling and heating systems. These help both people and machines – whether electric or combustion engines – adapt to varying environmental conditions on land, water, and in the air. Climate systems and all their components must endure high load cycles over time. Instead of testing durability in real operation, manufacturers can now flexibly and economically test their components in fast-forward mode using the pressure change test stand from Poppe + Potthoff Maschinenbau at an early stage of development. The component, for example, a... Frequency: 0.2 Hz Medium temperature heating circuit: +20° C to +140° C / Heating power at 12 KW Medium temperature cooling circuit: +20° C to -40° C / Cooling power at 5 KW down to -30° C and at 2 KW down to -40° C Test medium: Water - glycol mixture / pure glycol Ambient temperatures: -40° C to 140° C Flow rate control: 3 to 30 l/min dynamic pressure change: 0.2 to 10 bar
