The precision chiller PCU-R Series has a cooling cycle utilizing three electronic expansion valves and an innovative parallel task control that provides PID control of the chiller’s parallel heaters. This feature combines wide range with precision control, something that older inverter control and hot gas control chillers had trouble achieving. With a minus 10 to 80℃ temperature range and ±0.5℃ accuracy, these chillers can be used in a wide range of situations that require precise cycling water temperature regulation. Moreover, a multistage centrifugal pump using special blades that rapidly rotate in a horizontal direction achieves excellent water feeding capacity and pulsation-free, high-pressure pumping.
