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

Featuring a microprocessor PID temperature controller and powerful recirculating pump, the C30 provides stable cooling performance down to -30°C (-22°F) while maintaining consistent coolant circulation. With a large 30-liter stainless steel reservoir and increased cooling capacity, this model is specifically designed for 20L rotary evaporators and large laboratory distillation systems.

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

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