The Across International C20 Recirculating Chiller is a high-performance thermostatic laboratory chiller designed for applications requiring precise temperature control and reliable cooling performance. This closed-loop recirculating chiller is ideal for cooling laboratory equipment such as rotary evaporators, analytical instrumentation, vacuum systems, laser etching systems, ICP instruments, plasma etching equipment, and jacketed reactors.

Powered by a compressor-based cooling system and microprocessor PID temperature controller, the C20 provides dependable temperature regulation from -20°C to 99°C. The integrated 20 L/min recirculating pump ensures consistent fluid flow, allowing efficient heat transfer and stable operating conditions for laboratory processes.

Equipped with a 2nd generation 7-inch TFT touchscreen controller, the system provides intuitive operation and precise temperature adjustments, making it an ideal cooling solution for laboratories requiring accurate temperature control below ambient levels.

Note: The ultimate temperature of -20°C is measured under no-load conditions.
