The industrial chiller is one of the indispensable elements used in a number of production environments where temperatures need to be controlled. It is vital for machinery, product and process temperatures to be under control irrespective of whether we talk about the plastic, pharmaceutical, food processing or chemical industry. Companies use the services of industrial chiller manufacturers in order to get reliable equipment. However, the regular maintenance and correct use of chillers is not less important.
In this blog you will learn how to maintain your chiller and use it properly in order to ensure its efficient work. Also, you will find some information about industrial chiller working principle, different kinds of such chillers as well as useful recommendations by leading industrial chiller manufacturers in India.
The industrial chiller is the device which cools down liquids through vapor compression or absorption refrigeration cycles. Then the cooled liquid is used in the devices which require cooling.
Industrial chiller working principle involves heat exchange where the refrigerant takes the process water's heat and gives off to the air through the condenser.
Fun Fact: “Industrial chillers can remove heat so efficiently that some large-scale systems used in skyscrapers and data centers are capable of producing enough cooling power to freeze an Olympic-sized swimming pool within hours — yet they run silently behind walls, completely invisible to the people they serve!”
The following are some of the industrial chiller types:
Air-cooled chillers are used for external cooling air which help to cool the chillers by use of finned coils of condenser and axial fans.
These use a scroll compressor where the refrigerant compresses via the spiraling motion of the components. Scroll chillers are suitable for moderate and small-sized cooling needs.
Water-cooled chillers are used to provide an external cooling tower to lower the heat. They are normally applied in big industries and large manufacturing units.
Unlike other types, absorption chillers operate on heat rather than electrical energy and utilize a refrigerant/absorbent combination. These are best suited for operations with sources of waste heat or steam.
These can be used for industrial cooling applications that involve low temperature requirements and freeze prevention, thus making them the best choice for chemical processing plants and pharmaceutical facilities.
Rotary screw chiller has a compressor with a rotary screw design, hence providing continuous cooling performance at maximum efficiency for industrial uses.
They provide high efficiency, reliability, long-lasting operation, and high performance, making them suitable for industrial applications from Industrial Chiller suppliers in India.
Did you know? “Modern industrial chillers don't actually "create cold" — they move heat. They work by absorbing heat from a process or space and dumping it elsewhere (usually outside). This is why a chiller's efficiency is measured in COP (Coefficient of Performance) — a top-tier chiller can move 5–7 units of heat energy for every 1 unit of electrical energy it consumes. Essentially, they're heat-moving machines, not cold-making ones!”
Here are some of the tips:
Maintenance is necessary for filters, coils, and condensers, among the other components, should be regularly inspected and cleaned. The build-up of dirt and dust reduces the rate of heat exchange and the machine labors.
The cooling process is by the refrigerant. The quantity of any wrong refrigerant will render the cooling procedure less efficient and will require higher energy levels. Remember to check and maintain the amount of refrigerant in optimum conditions as recommended by well known Indian Chiller Industrial Manufacturers.
In the case of water cooled chillers, water quality is essential. The impurities can lead to scaling, corrosion and fouling thus reducing efficiency of the machine. You should use treated water for better operation.
Operating a chiller under extreme loading conditions makes it less efficient. It is crucial to balance the load with the cooling requirements to have efficient performance.
When it comes to evaporators, it is extremely important to clean them at regular intervals. Even a speck of dirt can lower the machine efficiency.
Air-cooled chillers should be allowed to freely circulate air. The overheating can be experienced whenever the correct airflow is not maintained and thus will have poor performance.
Loose connections, faulty wiring or faulty parts can influence performance. A check-up of all the electrical systems assists in ensuring safety and proper operation.
The present-day chillers have control systems which can detect performance levels and change their setting automatically. These controls help in maintaining efficiency and minimizing manual labor.
Despite proper maintenance practices, expert service is necessary from time to time. Many leading Industrial Chiller Suppliers India like Aquatech Plus provide after sales services.
‘Aquatech Plus Private Limited, established in 2014, is a well-known manufacturer of industrial chillers. The company is managed by a team of experts with over 17+ years of industry experience, ensuring high-quality engineering and reliable solutions. The Husain Shersiya (Director of Aquatech Plus Pvt. Ltd) founder, operates experienced leadership focused on innovation and efficiency. Over the years, Aquatech Plus has built a strong reputation in delivering advanced cooling and water purification systems for various industrial applications across India.’
Key common issues that affect the efficiency are:
Mineral deposits will cause inefficiency in heat transfer resulting in high energy usage.
Leakages will cause interruptions in the process of cooling.
Faulty installation can result in airflow limitations and improper heat exchange in the process.
Inefficiency caused due to neglect of regular maintenance is common.
The best Industrial Chiller Manufacturers use sophisticated technology to build their systems which will be energy-efficient with long-lasting components.
Historic Fact: “The concept of mechanical refrigeration — the backbone of industrial chillers — dates back to 1851, when Dr. John Gorrie, an American physician, patented the first mechanical refrigeration machine. He originally built it to cool hospital rooms for yellow fever patients in Florida. His pioneering work laid the groundwork for what would eventually evolve into the massive industrial chiller systems used today in manufacturing, pharmaceuticals, food processing, and HVAC systems worldwide. By the 1920s–30s, large-scale vapor-compression chillers began appearing in commercial buildings, revolutionizing indoor climate control forever.”
