The Across International C30-40 Recirculating Chiller is a high-capacity thermostatic laboratory chiller designed for demanding cooling applications requiring precise temperature control and powerful cooling below ambient temperatures. This compressor-based closed-loop recirculating chiller provides reliable cooling for large laboratory systems including rotary evaporators, analytical instrumentation, vacuum systems, ICP equipment, plasma etching systems, laser etching equipment, and jacketed reactors.

Powered by a high-performance compressor and microprocessor PID temperature controller, the C30-40 delivers stable cooling performance down to -30°C (-22°F) while maintaining consistent coolant circulation. The system features a large 40-liter stainless steel reservoir and high cooling capacity up to 5,000W, making it ideal for 50L rotary evaporators and large-scale laboratory distillation systems.

This recirculating chiller also serves as an efficient tap water replacement, eliminating water waste while providing stable and eco-friendly cooling for laboratory processes.

Note: The ultimate temperature of -30°C (-22°F) is measured under no-load conditions.
