Selecting the correct chiller - Pfannenberg

Heat is a single common by-product of today‘s manufacturing machines that include the advanced automation technology required for both high speed operation and high precision. Components such as spindle motors, variable frequency drives, laser and x-ray sources all require cooling to operate properly and reliably – most often in the very adverse manufacturing environments.

With manufacturing space at a premium, machine packages have become smaller and liquid cooling has emerged as the most efficient and economical means of removing process heat. Liquid cooling is especially well adapted to hot, dirty environments, where it provides a method of removing the heat from the machine and not contributing additional heat back into the environment.

Step 1: Determine the heat load.

It is important to determine the heat load of your application to ensure the chosen chiller is big enough for the intended application. 

There are several ways to determine the heat load (in kW) but understanding the process is essential to calculating an accurate heat load.

Step 2: Determine the coolant type, temperature & flow rate.

When the heat load is known, the next step is to determine the coolant, its target temperature and the flow rate that the chiller must provide to the process. This is determined by the method from which the heat is transferred from the process to the coolant and the type of coolant being used. For example, water has different characteristics than oil.

Step 4: Use chiller performance curves.

Now use the chiller performance curves available to select a chiller model that meets or exceeds the required capacity based on the chilled water supply temperature and the highest expected ambient air temperature. Consideration should be given to the safety margin of the application with respect to available frame sizes to maximise the value of the chiller selection. Find all Pfannenberg chillers performance curves in the related product page.
