PCW (Process Cooling Water) System:

PCW is a compact, skid-mounted system that circulates process water at a consistent temperature and pressure to the application’s point of use and back, allowing for more efficient and stable use of water-cooled machines, equipment, and instruments. Many process tools, particularly in the semiconductor and solar industries, generate heat during their use. This heat must be removed from the process on a continuous basis during tool operation.

CDA (Compressed Dry Air) System:

CDA is a system used to generate and distribute clean, dry, and compressed air in various industrial applications. It is commonly used in industries such as semiconductors, biochemical and pharmaceuticals, food and beverages, electronics, automotive, and manufacturing plants. As a reputable service provider, we provide top-quality services while adhering to ISO guidelines, local laws, regulations, and industry standards and also prioritize fulfilling our customers’ unique requirements.

The CDA system typically consists of the following components:

Compressor: The compressor is responsible for compressing the ambient air and raising its pressure. It can be a rotary screw compressor, reciprocating compressor, or centrifugal compressor, depending on the application and requirements.

Dew Point Monitors: Dew point monitors are used to measure the dew point temperature of the compressed air. They indicate the temperature at which moisture will condense, helping to determine the system’s efficiency and ensure the air remains within the required dew point range.

Temperature Sensors: Temperature sensors are used to monitor the temperature of the compressed air at various points in the system. They provide valuable data for system control and can help detect abnormal temperature conditions that may affect the air quality or system performance.

Control Panels and Programmable Logic Controllers (PLCs): Control panels and PLCs are used to centralize the control and monitoring of the CDA system. They enable operators to set parameters, monitor system performance, and receive alerts or alarms for any deviations or faults.

Aftercooler: After compression, the air temperature is usually high. The aftercooler is used to cool down the compressed air by removing excess heat, allowing moisture to condense.

Moisture Separators: These separators are designed to remove condensed moisture from the compressed air. They are often installed after the aftercooler and help eliminate water droplets and larger particles.

Air Dryer: The air dryer is a critical component of the CDA system. It removes the remaining moisture from the compressed air to achieve the desired level of dryness. Refrigerated air dryers, desiccant air dryers, or membrane air dryers, as mentioned in the previous response, can be used depending on the required dew point and application.

Filters: Filters are installed to remove contaminants, such as oil, dust, and solid particles, from the compressed air. They ensure the delivery of clean and high-quality compressed air to downstream processes.

Storage Tanks: Storage tanks or receivers are used to store the compressed air and provide a buffer for sudden demand spikes. They help maintain a steady supply of compressed air and reduce energy consumption by allowing the compressor to operate in cycles.

Distribution System: The CDA system includes a network of pipes and valves to distribute the compressed air to various points of use within the facility. The distribution system should be properly designed to minimize pressure drops and ensure efficient and reliable delivery of compressed air.
