Industrial Process Chillers: How They Work

When it comes to keeping industrial systems running smoothly, temperature control plays a critical role. That’s where an industrial process chiller steps in. But what exactly is it, how does it work, and why is it essential in so many manufacturing settings?

In this blog post, we’ll break down the basics of industrial process chillers, explore their key applications in manufacturing, and highlight how solutions like Trane’s MTA TAEevo TECH line are redefining process cooling performance.

What is an industrial process chiller?

An industrial process chiller is a type of refrigeration system designed to remove heat from a process or piece of equipment. Unlike comfort chillers, which cool air in buildings for occupant comfort, process chillers are focused purely on precise and reliable temperature control for industrial operations.

Process chiller systems work by circulating a coolant—usually water or a water/glycol mixture—through heat exchangers to absorb heat generated during industrial processes. The heat is then transferred to the environment via a refrigeration cycle. This continuous cooling helps prevent overheating, improve product quality, and maintain consistent operating conditions.

What are the components of a process chiller?

Every process chiller is built around the same core components:

  • Compressor: Drives the refrigeration cycle by compressing refrigerant gas.
  • Absorbs heat from the process fluid.
  • Condenser: Releases heat to the environment.
  • Expansion Valve: Regulates refrigerant flow into the evaporator.
  • Pump and Reservoir: Circulate and store the chilled fluid.

The type and configuration of each process chiller component can vary depending on cooling load, environmental conditions, and industry requirements.

Where are industrial process chillers used?

Industrial process chillers are used across a wide range of industries. Wherever heat needs to be controlled, you’ll find a chiller working behind the scenes.

Here are some common applications:

  1. Plastics Manufacturing: Injection molding and extrusion processes generate significant heat. Chillers help maintain mold temperatures, reduce cycle times, and prevent product defects.
  2. Food and Beverage: From dairy production to breweries, chillers are essential for helping to keep  ingredients and finished products at precise temperatures. They also help maintain hygienic conditions during processing and storage.
  3. Pharmaceuticals and Chemicals: Precise temperature control is vital in chemical reactions and formulations. Chillers provide consistent cooling for reactors, mixers, and storage tanks.
  4. Metalworking: Processes like welding, laser cutting, and CNC machining generate localized heat that can damage tools and materials. Chillers help dissipate this heat effectively.
  5. Printing: In high-speed printing operations, maintaining the right ink and roller temperatures is crucial for image quality and consistency.

What are the benefits of process cooling in manufacturing?

Effective process cooling brings a range of benefits:

  • Improved Product Quality: Stable temperatures mean consistent output.
  • Increased Equipment Lifespan: Preventing overheating protects sensitive components.
  • Operational Efficiency: Cooling allows for faster production cycles and reduced downtime.
  • Energy Savings: Modern chillers are designed for high efficiency and low power consumption.

Choosing the Right Process Chiller

When selecting a process chiller, it’s important to consider:

  • Cooling Capacity: Match the chiller size to your process load.
  • Fluid Type and Flow Rate: Determine whether you need water, glycol, or a specific mix.
  • Environmental Conditions: Indoor vs. outdoor placement, ambient temperature extremes.

FAQs About Process Chillers

What is the difference between a process chiller and an HVAC chiller?

Process chillers are designed for industrial cooling with tight temperature tolerances, while HVAC chillers focus on human comfort in buildings.

Can process chillers be used year-round?

Yes. Many are designed for 24/7, year-round operation, including in challenging ambient conditions.

Do I need a closed-loop or open-loop chiller system? 

Closed-loop chiller systems are generally preferred for cleanliness and efficiency, especially in sensitive applications like pharmaceuticals and electronics.
