Terminal velocity ….…. Don’t let it kill your heat exchanger!

Ensuring the correct velocity of cooling medium through the heat exchanger is vital to the long term health of the unit. Get it wrong and results could be terminal.

Terminal Velocity

The velocity (or flow rate) of the fluid that circulates through a typical shell and tube heat exchanger is extremely important. Not only can it have a direct bearing on the heat transfer efficiency of the heat exchanger, in instances where the incorrect flow rate is used, it is often the cause of premature failure…

What is counter flow? Why is it more efficient?

In a shell and tube heat exchanger, coolant usually flows through the central ‘tube core’ to cool hot oil, water or air, which passes over and around the tubes. The direction in which the two fluids travel through the heat exchanger can be either ‘parallel flow’ or ‘counter flow’. In this article we are looking…

Single, double or triple pass cooling – what’s the difference?

Getting the right specification for your heat exchanger can make a significant difference to the performance and life expectancy of the unit. Here we discuss the importance of single, double and triple pass cooling. Every shell and tube heat exchanger carries a flow of cooling water through its central tube core. But depending on its…
