Industrial chillers and similar cooling systems can represent a significant investment and yet, they are absolutely essential in order to guarantee that operations run smoothly. There are many models and configurations available on the open market and choosing the correct option can be confusing at times. Let us take a look at the primary metrics that need to be taken into account well before you commit to a specific brand.
Knowing the Predicted Heat Load
Process cooling systems are intended to mitigate the heat associated with specific applications. Naturally, this thermal load will vary. This is why experts recommend that you determine the associated heat load in order to ensure that the cooling equipment can handle the tasks involved. Most users will measure this load in reference to British Thermal Units (BTUs).
Indoor Versus Outdoor Needs
Many types of cooling equipment are intended to be used within specific environments. For example, indoor applications will often be associated with higher ambient temperatures and relatively dirty surroundings. Outdoor units must be able to withstand other variables such as humidity and the elements. Please note that certain environments could dictate that accessories such as specially designed air filters and larger sump heaters are needed.
Understand Processing Cooling Performance Curves
Performance curves will need to consider metrics such as the temperature of the chilled liquid supply as well as the external ambient air temperature. Any model must be able to match or supersede these variables in order to ensure efficiency from a long-term point of view. Obtaining an accurate reading of these factors will also increase safety margins.
Pressure and Flow Rate
The ability of an industrial chiller to be successfully integrated into a system will also depend upon its ability to meet sufficient pressure levels and water flow rates. It only stands to reason that larger pieces of machinery including CNC fabrication units will require more cooling than hardware such as a network server. Make certain that the cooling apparatus in question meets the requirements stipulated by any third-party devices. It is also worth mentioning that some frameworks employ smaller pipes to transport fluid over longer distances. This can sometimes result in a drop-in pressure. Be sure to take these losses into account.
Sanitary Considerations
There are some instances when industrial chillers are employed in areas that must adhere to sanitary guidelines. One common example can be seen in the food services industry. In such cases, a cooler must be washed and cleaned on a regular basis. Not all designs offer this possibility. The unit will therefore need to be able to withstand chemicals that might otherwise cause pitting and corrosion.
This type of equipment can easily be valued in the thousands of pounds. Selecting the correct make and model will offer cost-effective solutions and the lifespan of the cooler can be dramatically increased. As always, performing a fair amount of research in advance is the best way to make an informed decision.
