Recirculating Chiller - Cooling Bath Circulator - -10 to -40°C - 6.8 to 98 L

The Master Science Recirculating Chiller uses a sealed compressor and nickel-plated copper coils on the tank wall to cool the bath liquid, then pumps it to the jacket of a glass reactor, a rotary evaporator or a condenser coil. Cooled liquid returns to the unit in a closed loop.

The open bath can also hold flasks or containers directly for cooling or low-temperature reactions. Three sizes cover minimum temperatures of -10, -30 and -40 °C.

Key Benefits

• Wide cooling range: the Master Science Recirculating Chiller reaches down to -40 °C.
• Precise control: PT100 sensor and ±0.1 °C accuracy.
• Two ways to cool: circulate to equipment or immerse vessels in the bath.
• Sized for pilot work: up to 23 kW cooling for large reactors.
• Protected compressor: delay, over-current and overheat protection.

For small rotary evaporators, a Master Science compact refrigerated circulator may be enough.

Common Laboratory Problems and How This Chiller Helps

How the Master Science Recirculating Chiller deals with frequent cooling needs:

• Ice baths that warm up: continuous mechanical cooling.
• Exothermic reactions overheating: high cooling capacity.
• Unstable reaction temperature: ±0.1 °C control.
• Separate units for bath and circulation: one unit does both.
