The Across International C80-10 Recirculating Chiller is an ultra-low temperature laboratory cooling system designed for applications requiring precise temperature control at extremely low temperatures. This high-performance closed-loop thermostatic chiller provides reliable cooling for laboratory equipment such as jacketed reactors, rotary evaporators, analytical instrumentation, vacuum systems, ICP systems, plasma etching equipment, and laser systems.

Powered by a dual-compressor cascade refrigeration system, the C80-10 delivers cooling performance down to -75°C (-103°F) while maintaining stable temperature control through a microprocessor PID temperature controller. The system includes a powerful 30 L/min recirculating pump and stainless steel reservoir, ensuring efficient heat transfer and dependable cooling for demanding laboratory applications.

Designed for industrial laboratory use, the C80-10 offers plug-and-play installation, durable steel construction, and a large cooling capacity suitable for 20L jacketed reactors and advanced chemical processing systems.

Note: Ultimate temperatures of -75°C are measured under no-load conditions.
