Primary Industries for Process Cooling Applications

Process cooling fan applications are found across industries. However, because they are often used to remove heat between process applications like dryers, burners, and boilers, any or all of these industries may require process cooling:

Process Cooling Fan Selection & Specification

Process cooling fans (blowers) most often sit outside the gas stream and inject cooling ambient air at volumes and pressures that are dictated by the specific application.

Typical Process Cooling Fan Types

Fan Arrangements

Fan Arrangements indicate how the motors mount to and drive the fans. The specification will depend on your application and the fan(s) selected. Here are two examples:

Arrangement 1 – Belt Drive with an overhung impeller. The fan and motor mount separately to a unitary base.

Arrangement 8 – Direct Drive with an overhung impeller. The fan shaft is directly coupled to the motor shaft with a flexible coupling.

Accessories & Design

“Pushing” ambient air for process cooling involves less wear-and-tear on the fan than dirty and hot airstreams. While ambient air may not be as hard on the fan compared to more extreme conditions, fan/system imbalance and excessive vibration can still be a problem. It’s critical that fan vibration levels are monitored and addressed if they exceed recommended levels.

Proximity to high temperatures and possibly corrosive gasses may also require customizing process cooling fans for these extremes, including their temperature variations. Additionally, in many cooling applications, two fans are required, either for redundancy or for additional pressure.

Here are just some of the accessories and features you may see in process cooling fan applications:
