Case studies

A customer who is promoting the shift to HFC alternative refrigerant equipment updated their existing chiller to the PCU-NE series HFC alternative chiller. The application is cooling welding torches. The customer was measuring the chiller's return water temperature with an external temperature sensor to prevent pipe blockages inside the torch. The PCU-NE series has a function that display the external temperature sensor value on the LCD panel of the chiller body, and since its introduction, the customer has been very pleased with how much easier it is to check the temperature.

When the existing chiller broke down, they upgraded to the PCU-NE series HFC alternative chiller. The application was to control the temperature of the cooling water for a sputtering device. The sputtering device would shut down in an emergency if the cooling water temperature became too high, which would result in a large loss when producing expensive workpieces. The high control stability, flow rate, head, and other product specifications of HFC alternative chiller were highly rated, leading to their decision to adopt it.

A customer using vacuum deposition equipment has adopted the PCU-R series Precision chillers. Highly stability temperature-controlled circulating water is required to precisely control film thickness and form a uniform film. The PCU-R series controls circulating water with a high stability stability of ±0.05°C, and its multi-stage centrifugal pump allows for pulsation-free water delivery, which was highly praised and led to its adoption.

A customer who was considering countermeasures for the high temperature of hydraulic oil in a large hydraulic press in an underground pit decided to adopt the high-performance chiller PCU-SL series. Since there was not enough space to install it in the underground pit, we proposed indirect cooling with a chiller. The customer also appreciated the tough structure of the PCU-SL series, which can maintain cooling capacity even in a harsh on-site environment with oil mist and dust flying around.

The high-performance PCU-SL series chiller was selected following an update to the aging chiller that was installed to cool the micro transmitter when the vulcanizer was introduced. The PCU-SL series has a ventilation path on the top of the main body, which makes the intake air volume more uniform compared to conventional single-surface intake chillers and prevents capacity decline when filter clogging, which was highly evaluated and led to the customer's selection.

high-performance chiller PCU-SL series was adopted to indirectly cool the coolant tanks of machine tools. By installing the chiller outdoors, the chiller can be installed in a space-saving manner within the factory, and the factory's heat exhaust can be suppressed, which was highly evaluated. The PCU-SL series has high water performance (IPX4) and comes with a high-lift pump as standard, so it can be used safely even in remote outdoor locations.

Eliminates insufficient cooling that often occurs during times of high ambient temperature, such as summer.
This contributes to reducing the product defect rate.

Cooling water is used to cool the oscillators and coils that rise in temperature during heating, as well as to quench the heat-treated products.
In the summer, the ambient temperature rises and the cooling water temperature also tends to rise, but stable cooling can be achieved by using a chiller.

Welding conditions are stabilized by maintaining a constant temperature around the welding power supply and torch.

Maintaining a uniform roll temperature contributes to improving product quality.

It keeps the temperature, flow rate, and discharge pressure of the cooling water in the substrate cooling plate and vacuum chamber constant.

By regulating the cooling water temperature at a constant level, the reaction chamber, plasma electrodes, and substrates are kept at optimal temperatures.

To improve takt time by annealing at the optimum temperature, stage cooling is required.

Stabilizing the quality of stored liquids leads to higher product quality and improved productivity.
Food industry: raw material temperature control, mixing process, brewing process
Chemical and resin industry: temperature control of raw materials, removal of reaction heat
Electrical and electronics industry: Stabilizing the viscosity of resist liquid, etc.

It is possible to control the temperature of the stage with high stability and to supply a stable amount of cooling water to the lamp, which is the heat source.
This minimizes variations between lots and improves quality.

In precision machining machines, which require high stability, even a slight change in temperature can cause expansion and contraction of the product and spindle.
High temperature control that can achieve the required high processing stability contributes to improved yield.

To maintain stable output from a laser processing machine, it is essential to cool the laser oscillator and regulate the temperature of the optical system.
High-stability temperature control prevents condensation on the equipment and stabilizes laser output.

The PCU-R series can be set to temperatures ranging from -10°C to 80°C with just one unit.
This allows analysis and testing at a variety of temperature ranges to be performed with a single chiller.

If the temperature of the ultraviolet lamp becomes too high, the luminous efficiency and lifespan will decrease, so cooling is necessary.

If power supply or measuring part of the inspection equipment generates heat, it can lead to equipment malfunctions and measurement errors.
Stabilizing circulating water makes it possible to continuously perform highly stability and stable testing.

High vacuum pumps and water-sealed vacuum pumps lose vacuum when the cooling water temperature rises.
By keeping the cooling water temperature constant, cycle time can be shortened and quality improved.

The viscosity of coating agents changes with temperature, which can significantly affect the amount of coating and film thickness. Also, adhesives and other materials can deteriorate due to temperature changes.
Maintaining a constant temperature for coating and application agents contributes greatly to improving quality.
