A Step-by-Step Guide to Selecting an Industrial Water Chiller

There is no one-size-fits-all industrial water chiller. Your choice should depend on certain factors unique to your application, environment, and needs. For manufacturing, industrial chillers reduce the threat of spoilage and product contamination caused by excess heat in an application or process. They protect the integrity of a process by eliminating excess heat from applications and equipment, which may be sensitive to high temperatures, including those in the printing, beverage, food, and plastics industries.

Industrial water chillers also decrease your water consumption by using and recirculating your plant’s water supply. This way, your cooling costs are reduced, and you can eliminate the need to connect to the municipal wastewater discharge and water supply systems.

How to choose a chiller

There are things you must consider when choosing an appropriate industrial water chiller.

Process cooling fluid

Determine compatibility between the equipment and the cooling fluid. A specific fluid’s performance depends on its properties at a given temperature, such as boiling and freezing points, viscosity, and heat. Refer to the fluids and materials you’ll use, as incorrectly sized systems increase the potential for early seal degradation and corrosion.

The heat load

Know your application’s heat load to ensure an appropriate-sized industrial water chiller for your application. Determine this factor in BTU based on your process for an accurate answer.

Cooling fluid temperature

Know the performance data of the chiller. The cooling capacity is directly impacted by the set point temperature, meaning there’s a direct relationship between the total cooling capacity and the temperature at which it is set. Decreasing temperatures increases the refrigeration system’s load, and increasing the temperature does the opposite.

Flow requirements and process pressure

Check the pump’s size and performance to determine the system’s pressure loss and necessary flow rate. When you know the heat load, you can identify the coolant, flow rate, and target temperature the chiller must deliver.

Installation environment

Where will you install the industrial water chiller? Dirty atmospheres and high temperatures are common indoors, and high and low ambient temperatures occur outdoors. Those factors can affect chiller sizing and the need for accessories like sump heaters and air filters.

Chiller and pump performance curves

Refer to the available chiller performance curves to identify an appropriate model that exceeds or meets the required capacity based on the highest ambient air temperature and chilled water supply temperature. You should also check the pump performance curves to ensure it can deliver sufficient pressure at the design flow rate based on the application.

The manufacturer

Buy an industrial water chiller from a reputable manufacturer specializing in cooling products with built-in protection. Make sure it comes with a good warranty.
