Recirculating Chiller LZ-RCC-A100 supplies steady low-temperature liquid circulation for reactions, evaporation, and freeze-drying setups. With a 21 L volume and minimum temperature of −20°C, it delivers a practical cooling capacity for extended operation. The 40–240 L/min circulating pump flow enables efficient coolant circulation, making it suitable for rotary evaporators, glass reactors, vacuum freeze-drying equipment, and other low-temperature laboratory applications.
