Here’s a picture of our embryonic test set up for the soon to be launched water cooled 4QD-300. On the left is our current air cooled load cell, ammeter, and data logger. Front right is the 4QD-300 fitted with the water cooled heatsink. Right rear is the control and pump for the water. We’ve left space for a second pump which will be needed when our water cooled load cell is ready. Can’t wait to run this lot and see what results we get.
