Case studies a chiller

A customer replacing chlorofluorocarbon equipment with non-freon-gas equipment updated an existing chiller with a non-freon-gas chiller PCU-NE Series. The chiller was installed to cool a welding torch. In order to do predictive maintenance for clogged piping in the torch, the customer measured the chiller's return water temperature with the eternal temperature sensor. The PCU-NE Series displays external temperature sensor readings in the unit's LCD panel, and after installing the chiller the customer was very impressed by how easy it is to check water temperature.

When an existing chiller broke down, the customer replaced it with a non-freon-gas chiller PCU-NE Series. The chiller is used to regulate cooling water temperature in a sputter apparatus. A sputter apparatus can quickly shutdown when cooling water temperature rises, and such shutdowns can be very costly when doing expensive production work. The customer was therefore impressed by the high quality of the nonfreon chiller's control precision, flow volume, lift, and other product specs, and decided to install it in his production line.

A customer using a vacuum vapor deposition system installs a precision chiller PCU-R Series. Meticulously controlling film thickness and forming a uniform layer of film requires precisely regulating circulation water temperature. Impressed by the ability of PCU-R Series chiller's to control circulation water within ±0.05℃ and their pulsation-free water delivery using a multi-stage centrifugal pump, the customer decided to install a PCU-R Series in his system.

The hydraulic oil in a large-capacity hydraulic press operating in an underground pit heated up, and the customer solved the problem by adopting a high-performance chiller PCU-SL Series. Because the underground pit does not provide enough space for installing a chiller, we recommended indirect cooling. Moreover, the customer was impressed by how the PCU-SL Series chiller's tough design enables the chiller to maintain cooling performance even in a harsh operating environment filled with oil mist and dust.

A customer installing a vulcanizer used the occasion to replace a worn out chiller equipped with a micro-transmitter for cooling with a high-performance chiller PCU-SL Series. PCU-SL Series chillers have a ventilation channel in the multi-sided upper part of the unit. The customer decided to install a PCU-SL Series chiller because he was impressed by how the chiller draws in air much more evenly compared to other chillers with one-sided ventilation and how this consistent airflow helps prevent drops in performance when filters clog.
