Heat exchangers are subjected to a range of potentially damaging forces. Thermal expansion, pressure pulsation, and vibration will all cause fatigue and eventual failure if the product is not designed and installed correctly. Our testing regime and validation process ensures that when you specify a Grayson product, you can have total peace of mind that it will perform above and beyond your specification.

Full thermal cycle testing

Our test meets and exceeds requirements of major European vehicle manufacturers

Full pressure pulsation testing

Minimum pass requirement is 250,000 cycles

Wind tunnel testing

Our calorimetric test rig allows us to test all new heat exchanger platforms (coolant, air, oil and refrigerant) to identify base line performance. From this data we can create our thermal prediction program allowing us to predict performance for the given application

Vehicle installation review

Service review of parts removal and system serviceability. Vibration analysis, validating AV mount choice and natural frequency sweep
