Precision Chillers

Compact, high-performance, and energy-efficient temperature control with a small footprint design, inverter technology, low-GWP refrigerants, and industry certifications to support stable and flexible semiconductor and industrial processes.

Compact Low-GWP
Precision Chiller Systems

Ebara Technologies’  RJ-CA and RJ-XA Series are compact, energy-efficient chiller systems designed for semiconductor manufacturing equipment, featuring advanced inverter control technology for improved performance and reduced power consumption. Using environmentally friendly refrigerants like CO₂ and low-GWP R513A, these models support global compliance while delivering precise temperature control and corrosion-resistant designs to enhance process stability, yield, and tool uptime.

Model RJ-CA

Model RJ-CA

Refrigerant Type

Refrigerant Type CO2 refrigerant with GWP = 1

Temperature Stability

Temperature Stability +/- 0.1C

Energy Saving

Energy Saving

The Model RJ-CA uses natural refrigerant (CO2) for semiconductor manufacturing equipment. The built-in ultra-compact canned pump and Ebara’s inverter control technology save space and energy. ± 0.1°C temperature control is possible, contributing to improved process stability and yield.

Model RJ-XA

Model RJ-XA

Refrigerant Type

Refrigerant Type low-GWP refrigerant with GWP <600

Temperature Stability

Temperature Stability +/- 0.1C

Energy Saving

Energy Saving

The Model RJ-XA uses a low GWP* refrigerant (R513A) that complies with global and USA environmental regulations. Does not use copper or brass materials for wetted parts. Stainless steel brazing process reduces the risk of corrosion and tool downtime. Energy efficient pump with inverter control reducing power consumption.
