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

Featuring a microprocessor PID temperature controller and powerful recirculating pump, the C30 delivers stable temperature control and consistent coolant flow for demanding laboratory processes. With a cooling capability down to -30°C (-22°F), this chiller is ideal for laboratories requiring deeper cooling capacity than standard recirculating chillers.

The system also serves as an efficient tap water replacement, eliminating water waste while delivering consistent and environmentally friendly cooling performance.

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