5 Things to Know Before Buying Air Chiller

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.

A quick guide to choosing the correct chiller:

As each industrial environment is different, Pfannenberg designed a 6-steps guide to help you select the proper chiller for your application:

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 BTU) 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 3: Identify Installation Environment

In what environment the chiller will be installed? Indoor applications for example can see high temperatures and dirty atmospheres, while outdoor installations can experience both low and high ambient temperatures. This can effect chiller sizing and require accessories such as air filters, sump heaters, etc.

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 maximize the value of the chiller selection. Find all Pfannenberg Chillers Performance Curves on Thermal Management Catalog.

Step 5: Check Pump performance curves

Check the pump performance curves available to ensure that the pump will provide enough pressure at the design flow rate to satisfy the application. Some liquid cooled systems have small coolant flow paths or longer distances that can have higher than average pressure losses.

Step 6: Final Selection

Finally, consider that the remaining application requirements such as power characteristics, control options, footprint, agency listing, color, etc. are met by the selected standard Pfannenberg chiller. Choosing a standard chiller will bring you greater reliability, easier service with common spare parts and global support.

CUSTOM ENGINEERED

These are not off the shelf parts. They are all engineered and custom built for the IcyBreeze. This is important and one of the reasons we can get 6 hours of runtime on a single charge of the battery. All of our parts are engineered to work perfectly with each other. There is no product in the world that can currently do what the IcyBreeze does.

It has twice the amount of foam as the leading coolers on the market and will keep ice up to 7 days when not using the AC function.
