Leading Process Chiller Manufacturers

Process chillers are used for products that require specific cooling temperatures to ensure the quality of the product. They are commonly used in breweries, dairies, food processing, pharmaceuticals, and other industrial processes that require temperature control. Process chillers have the same structure and design as all chillers: a compressor, condenser, evaporator, and expansion valve. Read More…

Process Chillers Process chillers are a type of industrial cooling system that is used when HVAC water chillers do not provide enough cooling power. They use refrigerants like ammonia and halocarbons to cool facilities, machinery and products during and after industrial processes that generate large amounts of heat. They provide very effective cooling, and may be compact and portable or centralized chiller systems that are installed indoors or outside.

However, they vary from other chillers because they cool as a part of production and manufacturing processes.

Process Chiller Working Principle

Process chillers can be air cooled or water cooled, with water cooled process chillers having a cooling tower. A unique feature of process chillers is their ability to withstand the harsh conditions of manufacturing environments. Their durable design is necessary for them to adapt to the requirements of an industrial processing application.

Process Chiller Phases

All chillers have four basic components (an evaporator, compressor, condenser, and expansion valve) that work together to complete the cooling process. Each component performs a vital role in ensuring that the proper process temperature is achieved. The various components undergo a thermodynamic process during cooling in four phases.

Phase One

The evaporator acts as a heat exchanger that collects and places heat in the refrigerant. The collected process heat boils the refrigerant, which changes it from a liquid to a low-pressure gas. During this phase, the coolant temperature lowers. Three types of evaporators are shell and tube, coil, and plate.

  • Shell and Tube

    Shell and tube evaporators are highly efficient and compact. The refrigerant passes from the expansion valve into the tubes, where the refrigerant evaporates.

  • Coil

    The refrigerant enters the coils from the expansion valve, where it is cooled in the coils before moving to the compressor.

  • Plate

    Plate evaporators have plates over which a thin liquid film passes to initiate evaporation.

Phase Two

From the evaporator, the low-pressure gas moves to the compressor at a low temperature, where it will be compressed to raise its temperature and pressure. Pressure and temperature increase are necessary for the heat from the refrigerant to be released in the condenser. The varieties of compressors include screw, scroll, centrifugal, and reciprocating. Each type compresses the refrigerant gas using different mechanisms.

Screw Compressor

Phase Three

Phase three is when the refrigerant enters the condenser under high pressure and at a high temperature. In the condenser, the heat is removed from the refrigerant, which changes from a gas to a liquid. Air or water is the cooling source in the condenser; fans are used for air cooling while water is used for water cooling.

Phase Four

At this phase, the heat from the process has been released, and the refrigerant is ready for reprocessing. A process chiller's structure moves the refrigerant from the evaporator to the condenser so that the heat from the manufacturing process is constantly removed. Between the condenser and the evaporator is the expansion valve, structured to control the flow of refrigerant into the evaporator.

Process Chiller Applications

There are endless uses for process chillers due to their flexibility and the need for cooling for many processes. For a product to meet its designed requirements, it must be produced at a specific temperature so that the method of production does not alter its properties. Process chillers cool both products and machinery during production.

Food Processing

Refrigeration is a vital part of the preservation and stability of foods and is the most common application for which cooling is required. Additionally, chillers are used in food production to ensure that products are kept at a constant temperature, especially in producing alcoholic beverages that temperature fluctuations can severely damage.

Fermentation Chiller

Metal Plating

The process of metal plating involves high-temperature electroplating or electroless plating. High temperatures are necessary to ensure a tight bond of the finish to the metal. Each process requires temperatures well over 300 °F (148.9 °C), which requires heavy-duty process chillers to remove the heat. The exceptionally elevated temperatures and harsh conditions demand the use of process chillers that are resilient enough to withstand the conditions.

Plastic Production

Plastic production is a process that requires the most precise and accurately controlled temperatures to avoid producing damaged or inferior products. The process has little margin for error since intense and elevated heat can melt the plastic and destroy a production run. Although the molds for plastic production do not have to achieve exceptionally high temperatures, their continual use requires that they remain heated for several hours.

In the case of extruded plastics, the extruded plastic has to be cooled in a bath at exactly the correct temperature. The bath water must also be circulated and cooled at each run. For cast plastic and extruded plastic, process chillers provide the necessary temperature control to ensure the quality of the products produced.

Critical Aspects of a Process Chiller

Certain characteristics and traits must be investigated when deciding to purchase a process chiller, the key factor of which is longevity and reliability. The quality of a product may depend on the performance of a process chiller, so as with all industrial equipment, its selection should be carefully considered.

Other critical aspects include:

  • Strength of Performance
  • Temperature Control
  • Hours of Continuous Operation
  • Capacity
  • Customization
  • Control Mechanism
  • Environmental Factors – Energy Efficiency
  • Reliability and Dependability
  • Process and Application
  • Footprint
