What is Chiller?

What is chiller and how does chiller systems work?

Chiller devices are special cooling systems used to control and regulate the temperature of liquids in a facility or system. These devices are designed not only for air conditioning purposes but also to prevent overheating of machines and systems used in industrial processes, increase productivity, and extend the equipment's lifespan.

Chiller devices primarily regulate temperature by cooling the liquid and circulating this cold liquid in a loop. These devices typically include a compressor, a condenser, an expansion valve, and an evaporator. The working principle involves the circulation of a cooling fluid controlled by an expansion valve. As this fluid circulates in the system, it heats up and returns to the cooling device, and this cycle is repeated continuously.

Types of Chiller Devices

They can be categorized into two types based on their purposes and technical specifications.

Air-Cooled Chiller: Uses a condenser where heat is exchanged with the surrounding air. Air-cooled chillers are often used in smaller and portable systems. They are suitable for models with cooling capacities smaller than 5kW or for selections that will operate in outdoor environments.

Water-Cooled Chiller: These chillers regulate temperature by cooling water through a condenser. This type does not heat the surrounding environment and does not affect room temperature. They are commonly used in larger facilities and industrial applications.

Circulating Chillers (laboratory mini-chillers): Circulating chillers are smaller-scale systems used to regulate the temperature of liquids. Laboratory applications, medical devices, and conditioning of samples within the liquid bath are common uses of circulating chillers. Labo's CH-1000 model, with an 8-liter bath capacity and a working range of -20°C to 40°C, has a cooling capacity of 1kW.



Benefits in Industry

These devices ensure process stability by precisely controlling the temperature of liquids. They offer standard conditions unaffected by seasonal temperature changes. Since the cooling process typically utilizes energy from the external environment, they provide high energy efficiency. Temperature control contributes to the extended lifespan of industrial equipment and optimal operation, increasing productivity. Optimal temperature conditions enhance the efficiency of machines and systems, improving business processes.

Application Fields

Used to control temperature in chemical processes, especially crucial in reactor applications. Utilized for temperature regulation in laboratories and medical devices.

Used for temperature control in plastic injection machines and extrusion systems. Liquid bath models are used for conditioning samples within the liquid.

Applied in power generation facilities, particularly for temperature control in power plants. In the electronics industry, used to control temperature in circuit board and semiconductor production, enhancing performance and durability.

In the automotive sector, employed for temperature control in engine and transmission tests, paint drying systems, and test chambers.

Used in aircraft manufacturing and maintenance facilities for thermal tests and assembly of spacecraft to control temperature. Critical in pharmaceutical production, biotechnological processes, and bioreactors for temperature control, enhancing product quality and efficiency. In paper production and the cellulose industry, provides temperature control to optimize production processes and improve paper quality.

These devices play a significant role in ensuring processes are conducted safely, efficiently, and consistently across various industries.

Chiller devices are utilized in various industrial applications and tests, providing significant benefits. The tests and analyses conducted with these devices contribute to the development of more reliable, efficient, and environmentally friendly products across industries. This leads to better living conditions, safe products, and environmentally friendly technologies for humanity.



When making a purchase;

 it is essential to determine the model based on the application and industry where the device will be used. Different industries may have different requirements, so evaluate whether the device is suitable for your specific application.

Cooling Capacity: Determine the cooling capacity needed by considering factors such as the volume of the liquid to be used and your cooling requirements. Choose the device accordingly.

Temperature Control Precision: Depending on your application requirements, the temperature control precision of the device is crucial. For applications that require precise control, chillers with higher precision may be preferred. There are chiller models available that provide temperature control precision up to 0.01°C.
