Precision Cooling for Critical Processes

Process chillers remove heat generated during industrial and manufacturing processes by circulating a coolant, typically water or a water/glycol mix, through a closed-loop system. Unlike general-purpose HVAC systems, which prioritize occupant comfort, process chillers are engineered for the demands of production environments, where temperature stability is directly tied to quality and safety.

These systems support critical outcomes in sectors such as:

  • Manufacturing and Industrial: Cooling equipment, stabilizing materials, and supporting continuous production
  • Food and Beverage: Regulating temperatures for fermentation, cold storage, and thermal-sensitive processes that ensure product safety and flavour integrity.
  • Pharmaceutical and Life Sciences: Ensuring precise environmental conditions for drug formulation, lab testing, and material storage in GMP-compliant facilities.
  • Medical Imaging and Diagnostics: Providing consistent cooling for MRI machines, CT scanners, PET systems, and other heat-sensitive diagnostic technologies.
  • Plastics and Rubber Manufacturing: Regulating mould temperatures and supporting extrusion processes for product consistency
  • Breweries and Wineries: Supporting fermentation stability, clarification, cold crashing, and packaging conditions for product consistency and shelf life.
  • Chemical Processing: Maintaining steady thermal conditions for heat-sensitive reactions and compound stabilization.

How Process Chillers Work

Every process chiller uses a closed-loop refrigeration cycle to absorb, transfer, and dissipate heat. The process is simple in theory, but optimized through advanced components and intelligent controls.

Core Components of Process Chillers:

  • Compressor: Scroll, screw, or centrifugal compressors compress the refrigerant and enable heat transfer.
  • Evaporator: Where process fluid gives up its heat to the refrigerant, essentially absorbing the process load.
  • Condenser: Either air-cooled or water-cooled, the condenser releases absorbed heat into the surrounding environment.
  • Pump System: Ensures consistent coolant flow and maintains system pressure.

Many process chillers also feature programmable control panels, alarms, and connectivity to building management systems for real-time monitoring and diagnostics.

Matching the System to the Application

Not all chillers are created equal. The right configuration depends on the environment, load profile, space availability, and cooling objectives. Lincoln Associates offers access to a full range of system types, helping clients find the best fit for their specific operational demands.

Types of Process Chillers:

  • Air-Cooled Chillers: Ideal for outdoor installation and lower maintenance needs; popular for small to mid-sized operations.
  • Water-Cooled Chillers: Highly efficient for larger facilities, though they require a water source and cooling tower.
  • Portable Chillers: Compact, mobile units designed for temporary cooling needs or modular operations.
  • Closed-Loop vs. Open-Loop Systems: Closed-loop designs minimize contamination risk and improve energy efficiency. Open-loop systems are simpler but more exposed to environmental variables.

Key Considerations for Selecting a Chiller

The performance of a process chiller is tied directly to how well it aligns with its intended application. Our engineering team helps clients assess the following:

  • Cooling Capacity: Correct sizing is essential to avoid short cycling or system strain.
  • Energy Efficiency: Look for variable speed compressors, free cooling options, and energy recovery systems.
  • Precision and Stability: Tighter temperature tolerances support higher quality outcomes and compliance in regulated environments.
  • Environmental Impact: Low-GWP refrigerants and high-efficiency components support sustainability goals.
  • Customization: We specialize in designing tailored systems that address legacy infrastructure, unique fluids, or physical constraints.

Tube Diameter

Use a caliper or tape measure to determine the outside diameter of the tubes.

If necessary, remove insulation to see the incoming and outgoing lines. Measure the diameter of the outside of the line to help determine connection size.

Standard connection types are MPT (male pipe thread), FPT (female pipe thread), and Copper Sweat Connection. MPT is threaded on the outside, FPT is threaded on the inside, and Copper Sweat is used for soldered connections

Fins per Inch

Using a ruler, count the number of fins on the coil within one inch. Normal fin counts will be between 4 and 14 FPI.

Fin Length

Measure in the direction of the tubes, regardless of which direction the tubes are running.

Fin Height

Measure in the direction of the fin.

Single, Double, and Half Serpentine

Rows are counted in the direction of airflow, no matter how the coil is installed. You can count rows by looking at either the header end or the return bend end of the coil. Note that headers or return bends may not be evenly spaced across the coil.

Fluid coils—hot water, chilled water, and glycol water—regulate building air temperature by heating or cooling air in Air Handling Units (AHUs). Constructed with multiple rows of tubes, typically copper, these coils efficiently transfer heat between air and circulating fluids. They are vital for year-round comfort, accommodating diverse fluids like glycols and thermal oils for varied HVAC needs.

Condenser coils transfer heat from refrigerant vapor to the outdoor air, ensuring efficient cooling in HVAC and refrigeration systems. Constructed from materials like copper or aluminum to maximize heat transfer, these coils are vital for maintaining precise temperature control in industrial and commercial environments.

Steam coils utilize the latent heat of steam, released during condensation from vapor to liquid. They feature efficient condensate management to prevent water buildup and ensure uniform steam distribution. Available in configurations for high and low-pressure applications, steam coils are highly effective for heating air in a wide range of environments.

Evaporator coils absorb heat from indoor air to cool and dehumidify spaces by evaporating refrigerant from liquid to vapor. Located indoors, these coils are essential for maintaining comfortable environments in industrial and commercial settings, offering excellent performance in cooling, process cooling, and dehumidification applications. They are versatile for use in Air Handling Units (AHUs), central systems, or duct installations.
