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

Powered by a compressor-based cooling system and advanced microprocessor PID temperature controller, the C30 provides dependable cooling performance down to -30°C (-22°F). A powerful centrifugal recirculating pump delivers up to 20 L/min flow, ensuring efficient heat transfer and stable system performance for demanding laboratory processes.

With an enlarged 17-liter stainless steel reservoir and increased cooling capacity, this model is specifically designed for 10L rotary evaporators and larger laboratory distillation systems.

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