Features for PCU-F Series

Unlike conventional chillers with a built-in pump and tank, the PCU-F Series chillers employ a pumpless and tankless structure for the main unit. This structure significantly enhances design flexibility, making it possible to build optimal cooling systems that can flexibly and efficiently meet various needs when deploying new equipment or improving existing equipment.

Cooling water that circulates while in contact with the external environment is called an open circuit. When a chiller with a built-in pump and tank is used in an open circuit, it is necessary to either make the load side a closed circuit or employ indirect cooling using a heat exchanger. The PCU-F Series chiller uses a pumpless and tankless structure, so it can be used in open circuits and operated without additional measures. This simplifies the design of cooling systems and allows for flexible operation.

A one-pass circuit uses cooling water only once before draining it, and is commonly used in cooling systems that utilize tap or well water. This is a type of open circuit where cooling water comes into contact with outside air, so using a chiller with a built-in pump and tank requires either sealing the load side or employing indirect cooling using a heat exchanger. PCU-F Series chillers use a pumpless and tankless structure, so no additional measures are required for operation in direct cooling even in one-pass circuits.

When cooling capacity is insufficient in an existing cooling circuit, a chiller with a built-in pump and tank requires careful attention to flow rate adjustment and piping/circuit design. However, PCU-F Series chillers can be directly inserted into existing circuits to improve cooling capacity without any additional adjustments due to its pumpless and tankless structure. This makes modification of existing cooling systems easy, and allows for flexible operation.

Synchronized control performs control so that the set temperature is changed by synchronizing it to the temperature measured by the external temperature sensor.

Cascade control performs control so that the temperature of the external measurement location becomes the set temperature.

The chiller records circulation water outlet temperature, the set temperature for circulation water, accumulated operating time, error date and time, and other important operation data. The chiller can record data in two minute intervals for up to one-and-a-half years. *When an error occurs, the chiller saves data in 5 second intervals from about 1 minute before the error occurred.
For more detailed analysis of operating conditions, data saved in the chiller can be transmitted via USB memory to a computer.

The chiller has a time calendar. Daily circulation water temperature, error history, and other data recorded by the drive recorder can be verified at any time with the time calendar.

You can use the external temperature sensor to measure the temperature of an external object and record the data in the chiller. You can record chiller operation data and external temperature data with a single unit.

To meet the rising demand for IoT compatible manufacturing work floors, the chiller is ethernet compatible. Besides performing data read and write with external communication Modbus/TCP, the chiller is also MC protocol and Socket communication format compatible. The chiller has the versatility for meeting all kinds of IoT era needs, including tracking operation performance, visualizing data, and remote operation.
