50RT low temperature water cooled screw chiller for chemical with 316 Stainless Steel Evaporator
A low temperature water-cooled screw chiller is a type of industrial cooling equipment designed to provide cooling at lower temperatures. It typically consists of a screw compressor, a water-cooled condenser, an evaporator, and a water circulation system.
The key features and benefits of a low temperature water-cooled screw chiller include:
Low temperature capability: This type of chiller is capable of achieving and maintaining lower water temperatures, typically down to -10°C or even lower, depending on the specific model.
Screw compressor technology: Screw compressors are known for their high efficiency and reliability in industrial cooling applications. They can handle a wide range of cooling loads and operate smoothly even under varying conditions.
Water-cooled condenser: The chiller utilizes a water-cooled condenser to dissipate heat from the refrigerant and maintain optimal operating temperatures. This allows for efficient heat transfer and cooling performance.
Precise temperature control: Low temperature water-cooled screw chillers are equipped with advanced temperature control systems that allow for precise regulation of water temperature. This is crucial for applications that require strict temperature control, such as in the pharmaceutical or chemical industry.
Anti-corrosion features: The use of materials such as nickel white copper or specialized coatings in the evaporator helps to protect against corrosion, which is particularly important when dealing with low temperature environments and certain chemicals.
Energy efficiency: Low temperature water-cooled screw chillers are designed to maximize energy efficiency, helping to reduce operational costs and minimize environmental impact. They often incorporate energy-saving features such as variable speed drives and optimized control algorithms.
Reliable operation: Industrial cooling systems need to be reliable and durable to meet the demands of continuous operation in industrial settings. Low temperature water-cooled screw chillers are designed for robust performance and are built to withstand the rigors of industrial environments.
Overall, a low temperature water-cooled screw chiller is a reliable and efficient solution for industrial applications that require precise and consistent low-temperature cooling.
The working principle of a low-temperature water-cooled screw chiller is as follows:
Refrigeration Cycle: The chiller operates based on the vapor compression refrigeration cycle. It uses a refrigerant, typically R404A or R22, which undergoes phase changes between a high-pressure gas and a low-pressure liquid to absorb heat from the process fluid.
Compressor: The chiller contains a screw compressor, which is the heart of the system. The compressor compresses the refrigerant vapor, increasing its pressure and temperature.
Condenser: The high-pressure, high-temperature refrigerant vapor then flows into the condenser. In the water-cooled system, the condenser is cooled by water that circulates through the condenser coils. As the refrigerant gives off heat, it condenses into a high-pressure liquid.
Expansion Valve: The high-pressure liquid refrigerant passes through an expansion valve, where its pressure is reduced. This results in a drop in temperature and the refrigerant changes into a low-pressure, low-temperature mixture of liquid and vapor.
Evaporator: The low-pressure refrigerant mixture enters the evaporator, which is in contact with the process fluid that needs to be cooled. Heat is transferred from the process fluid to the refrigerant, causing the refrigerant to evaporate. This absorbs heat from the process fluid and cools it down.
Refrigerant Return: The refrigerant vapor is then drawn back into the compressor to start the cycle again. The process fluid, now cooled, continues its flow to the desired application or process.
Overall, the low-temperature water-cooled screw chiller uses the principles of refrigeration to remove heat from the process fluid and maintain the desired low temperature. The continuous circulation of the refrigerant allows for efficient cooling and temperature control.
The main feature of a glycol water cooled chiller system includes:
Efficient Cooling: The glycol water mix provides effective cooling for various industrial processes, ensuring stable and reliable temperature control.
Anti-Freezing Protection: The addition of glycol prevents the water from freezing at low temperatures, making it suitable for applications in cold climates or where the cooling process requires lower temperatures.
Corrosion Prevention: The glycol in the system helps to inhibit corrosion and protect the components of the chiller system, extending its lifespan and reducing maintenance requirements.
Flexible Temperature Range: Glycol water cooled chiller systems can provide a wide range of temperature control, allowing for precise cooling requirements depending on the specific application.
Versatility: These chiller systems are suitable for various industries and applications, including food and beverage processing, pharmaceuticals, chemical production, HVAC systems, and more.
Energy-efficient Operation: Glycol water cooled chiller systems are designed for energy efficiency, with advanced compressors and heat exchange technology to optimize cooling performance and reduce energy consumption.
Reliable and Durable: The chiller system is built with robust components and is designed for continuous and long-term operation, ensuring reliable and consistent cooling performance.
Easy Maintenance: The chiller system is generally easy to maintain, with accessible components and controls for troubleshooting and routine service.
Overall, the glycol water cooled chiller system offers efficient and reliable cooling with anti-freezing protection and corrosion prevention, making it a suitable solution for various industrial applications that require precise temperature control.
