A process chiller, also known as an industrial chiller or process cooling chiller, is a refrigeration system specifically designed for cooling various industrial processes and applications. It is used to remove heat generated during manufacturing processes, machinery operations, or other industrial applications that require reliable cooling.
Process chillers are commonly used in industries such as plastics, pharmaceuticals, food and beverage, chemical processing, printing, and more. They are used to maintain consistent temperatures and ensure the efficiency and reliability of production processes.
The working principle of a process chiller involves circulating a refrigerant through a compressor, condenser, expansion valve, and evaporator. The refrigerant absorbs heat from the process being cooled and transfers it to the condenser, where it is expelled into the environment. The cooled refrigerant is then circulated back to the evaporator to continue the cooling cycle.
Process chillers are available in various types, including air-cooled chillers and water-cooled chillers. The choice between them depends on factors such as cooling requirements, available resources (such as water supply), and installation considerations. Both types have their own advantages and are suitable for different applications.
The main features of a process chiller include:
Reliable Cooling Capacity: Process chillers are designed to provide reliable and consistent cooling capacity to meet the specific requirements of industrial applications.
Precise Temperature Control: They offer precise temperature control to maintain stable process conditions, ensuring high-quality production and product consistency.
Efficient Energy Consumption: Process chillers are designed to be energy-efficient, utilizing advanced technologies such as variable speed drives and intelligent controls to optimize energy consumption and reduce operating costs.
Robust Construction: Process chillers are built to withstand harsh industrial environments and are equipped with durable components to ensure long-term operation and reliability.
Easy Maintenance: They are designed for easy maintenance and serviceability, with accessible components and user-friendly controls to simplify operation and upkeep.
Safety Features: Process chillers often incorporate safety features such as high-pressure and low-pressure alarms, temperature sensors, and safety shutdowns to protect the equipment and the process being cooled.
Overall, process chillers play a critical role in industrial applications by providing reliable and efficient cooling for various processes, helping to maintain optimal production conditions and ensuring product quality.

Industrial chiller is a type of chiller. Chillers can be divided into air-cooled chillers and water-cooled chillers.
Chiller is a kind of water cooling equipment that can provide constant temperature, constant flow and constant pressure. The principle of the chiller is to inject a certain amount of water into the internal water tank of the machine, cool the water through the chiller refrigeration system, and then use the water pump inside the machine to inject low-temperature frozen water into the equipment that needs to be cooled. The chilled water transfers the heat inside the machine. Take it away and return the high-temperature hot water to the water tank for cooling. This cycle exchanges cooling to achieve the cooling effect of the equipment.

Air-cooled chiller is a common industrial cooling equipment with the following advantages:
Independent cooling system: The air-cooled chiller adopts an independent air cooling system and does not require additional cooling water sources or cooling towers. This makes installation and operation relatively simple, saving installation and maintenance costs and space.
Wide range of applications: Air-cooled chillers are suitable for various industrial applications, including plastic processing, refrigeration and air conditioning systems, machining, printing and paper making. They provide reliable cooling for different equipment and processes.
High efficiency and energy saving: The air-cooled chiller adopts air cooling method and uses forced fans to circulate the air and take away the heat. Compared to traditional water-cooled systems, they do not require additional water pumps and cooling towers, thus saving energy and operating costs.
Flexibility and mobility: Since they do not need to be connected to an external cooling water source, air-cooled chillers are more flexible and can be moved to different locations more easily. This is useful for applications that require movement or changes in work location.
Easy maintenance: Compared with water cooling systems, air-cooled chillers are easier to maintain. There is no need to deal with problems such as scale, water treatment and water pump maintenance, reducing the complexity and cost of maintenance work.
Small footprint: Air-cooled chillers have a relatively small footprint as they do not require a cooling tower and water cooling system. This is very advantageous when space is limited.
However, it should be noted that air-cooled chillers may be slightly less efficient than water-cooled systems in heat dissipation efficiency, especially in high-temperature environments. In addition, since air cooling requires the use of fans, noise and vibration may occur. Therefore, when selecting cooling equipment, it is necessary to comprehensively consider the advantages and disadvantages based on specific needs and process requirements, and weigh various factors.
