Shell and Tube Evaporator: Utilizes high-efficiency heat exchange copper tubes housed within a seamless carbon steel shell. Features high heat exchange efficiency and an anti-freezing design; customization using specialized materials is available upon request.

Controller System:  As the "brain" of the chiller, the control system is critical; we utilize a programmable Siemens PLC + LCD Touch Screen. Multiple specifications available; optional RS485 remote control. There are also other control system brands available with lower cost.

Electricity Box: Using famous Brand Contactors, such as Schneider, ABB, LS,CHNT...... 

Refrigeration Parts: Famous Brand such as: Emerson, Danfoss......

Water-Cooled Design: The chiller uses water as the cooling medium, which is circulated through the system to remove heat from the industrial processes. It requires a water source and a cooling tower or an external water-cooling system.

Control System: The chiller is equipped with an advanced control system that allows for precise temperature control and operational settings. It may include features such as programmable logic controllers (PLCs), touch-screen displays, and remote control capabilities.

Safety Features: The chiller may come with various safety features, such as high/low-pressure protection, motor overload protection, anti-freezing protection, and phase sequence protection, ensuring safe and reliable operation.

Energy Efficiency: The chiller is designed to be energy-efficient, with features like variable frequency drives (VFD) and intelligent control algorithms that optimize the chiller's energy consumption and reduce operational costs.

Robust Construction: The chiller is built with durable materials and a robust construction to withstand the demands of industrial environments. It is designed for continuous operation and requires minimal maintenance.The 70 ton water cooled chiller use high quality semi-hermetic screw compressor Bitzer or Hanbell. Single and double compressors system optional. 

Advantages of the Dry evaporator water cooled screw chiller 

Water cooled screw chillers offer several advantages in industrial cooling applications:

Cooling Efficiency: Water cooled chillers are known for their cooling efficiency. They can maintain precise and stable temperature control, making them suitable for applications that require consistent cooling performance.
High Capacity: Water cooled screw chillers often have higher cooling capacities compared to their air cooled counterparts. This makes them suitable for cooling large industrial processes or equipment that generate high heat loads.
Energy Efficiency: Water cooled chillers can achieve higher energy efficiency due to the use of water as a cooling medium. They use less energy compared to air cooled chillers because water has higher heat transfer efficiency.
Reduced Noise Levels: Since the cooling is done using water, the noise levels of water cooled screw chillers are generally lower compared to air cooled chillers. This makes them more suitable for industrial environments where noise is a concern.
Flexibility in Installation: Water cooled chillers offer flexibility in installation as they can be placed indoors or outdoors. They require a separate water cooling tower or a water source for the heat exchange process.
Longer Service Life: Water cooled screw chillers typically have a longer service life compared to air cooled chillers. This is because water cooling helps maintain lower operating temperatures, reducing wear and tear on the compressor and other components.
Environmentally Friendly: Water cooled chillers are considered more environmentally friendly due to their higher energy efficiency, which results in lower greenhouse gas emissions compared to air cooled chillers.
It's important to note that water cooled screw chillers require proper water treatment and maintenance to prevent scaling, corrosion, and bacteria growth in the system. Regular maintenance and monitoring are necessary to ensure optimal performance and longevity of the chiller.

Water cooled screw chiller 50 ton is a specially designed cooling unit which can work efficiently even in an extreme tropical environment. It maintains consistent heat dissipation by chilled water of the condenser. Cooling tower is used together with the water cooled screw chiller.
