HFC alternative pump/tankless chiller
PCU-F series
Pumpless and tankless structure to meet a variety of needs at manufacturing sites
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.
Open circuit cooling
A cooling method in which chilled water circulates while in contact with the external environment is called an open circuit. When using a pump/tank built-in chiller in an open circuit, the load side must be sealed or indirectly cooled using a heat exchanger. The PCU-F series has a pump/tankless design, so it can be used in an open circuit and can be operated without any additional measures. This simplifies the design of the cooling system and enables flexible operation.
One-pass circuit cooling
A one-pass circuit is a cooling method in which chilled water is used only once and then discharged, and is often used for cooling using tap water or well water. Because it is a type of open circuit in which the cooling water comes into contact with outside air, when using a chiller with a built-in pump and tank, it is necessary to seal the load side or use indirect cooling with a heat exchanger. However, because the PCU-F series has a pump and tankless structure, direct cooling is possible even with a one-pass circuit and it can be operated without any additional measures.
Auxiliary cooling for existing circuit (cooling capacity enhancement)
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.
Temperature control using an external sensor
Chillers usually control the outlet temperature to a set temperature, but PCU-F Series chillers can perform temperature control using an external temperature sensor.
> Please refer to the catalog for details.
Synchronized control
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
Cascade control performs control so that the temperature of the external measurement location becomes the set temperature.
Uses non-freon-gas refrigerant, No more labor costs and time with Freon-gas.
Use non-freon-gas R1234yf refrigerant
In April 2015, Japan enacted the Fluorocarbons Recovery and Destruction Law. The law requires that operators of fluorocarbon emitting equipment observe six requirements, including regular detailed inspections and reporting leakage amounts. A revision of the law in 2020 to strengthen its provisions includes direct fines that bypass normal administrative procedures for equipment operators who commit violations of the law when discarding equipment.
The PCU-NE Series uses non-freon-gas R1234yf refrigerant. Businesses are able to lower their fluorocarbon-related costs because they are exempt from the Fluorocarbons Recovery and Destruction Law and thus are not required to collect and discard of refrigerant or perform periodic inspections.

The chiller provides everything you need to monitor operation around the clock
The first player in this industry market, The PCU-NE Series with a drive recorder
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.
Time calendar function
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.
Measure and record external temperature
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.
New user-friendly and secure basic functions
IoT compatible Modbus TCP
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.
| Remote monitoring | By outputting chiller circulation water outlet temperature, circulation water set temperature, external temperature, error output, and various other items, you can remotely monitor equipment operation from a PLC, touch panel, or other remote device. |
|---|---|
| Remote operation | You can control every chiller function remotely because you can use the chiller control panel from a remote location. |
| Connect to peripheral equipment | Along with monitoring the operation of manufacturing equipment, you can switch chiller cooling on and off, adjust circulation water temperature settings, and connect to peripheral equipment to control operation parameters. |
| Operation | Stop operation, error reset, key lock |
|---|---|
| Output | Error number, circulation water set temperature, circulation water outlet temperature, external temperature, accumulated operation time |
| Settings | Circulation water set temperature, water temperature upper/lower limit settings, timer settings, pump settings during errors, key lock settings |
