Low Temperature Cooling Circulator

Low Temperature Cooling Circulator

Drawell low-temperature cooling circulators provide controlled circulating coolant for laboratory instruments and temperature-sensitive processes. Available in compact and floor-type configurations, the series covers different cooling temperatures, circulation flows and bath volumes for applications ranging from rotary evaporation and analytical testing to microscopy, vacuum and process equipment.

Features of Low Temperature Cooling Circulator

  • Low-Temperature Circulation: Provides controlled circulating coolant for laboratory instruments and external cooling processes.
  • Stable Temperature Control: Microcomputer / PID temperature control maintains stable coolant temperature during operation.
  • External Cooling Support: Designed for continuous circulation through condensers, analytical instruments and other compatible equipment.
  • Corrosion-Resistant Circulation: Selected models use corrosion-resistant circulation components for low-temperature liquids.
  • Multiple Capacity Options: Compact and floor-type configurations are available for different cooling loads and circulation requirements.

Choose the Right Cooling Circulator

Applications of Low Temperature Cooling Circulator 

Chemical Lab

Chemical & Pharmaceutical Laboratories

Cooling support for rotary evaporators and molecular distillation systems used in evaporation, extraction, concentration and separation workflows.

Analytical Testing

Analytical Testing Laboratories

Provides stable circulating cooling for AAS, plasma emission spectrometers and direct-reading spectrometers during routine analytical testing.

Materials Lab

Materials & Microscopy Laboratories

Suitable for cooling scanning electron microscopes and fusion equipment used in materials analysis, microscopy and sample-preparation workflows.

Process Equipment

Semiconductor & Controlled-Environment Labs

Provides circulating cooling for plasma etching systems and glove boxes used in semiconductor and controlled-environment processes.

Food Testing

Food & Quality Testing

Cooling support for rotary evaporators and Kjeldahl systems used in food sample preparation, concentration and routine quality-testing workflows.

Cooling Capacity Matters

The minimum temperature alone does not determine whether a cooling circulator is suitable. Cooling capacity decreases as the coolant temperature becomes lower, so the required heat load should be checked at the actual operating temperature.

Cooling Capacity Matters

How to Choose a Low-Temperature Cooling Circulator?

For -10°C: Choose DW-YQ-5/10

For -20°C: Choose DW-YQ-5/20, DW-YQ-2/20SJ, DW-YQ-5/20SJ, or DW-YQ-20/20SJ

Do not focus solely on the minimum temperature; the key is to determine: How many watts of cooling are required at the actual operating temperature?

Options: 18 / 20 / 25 / 40 L/min

Options: 7 m / 15 m

Options: 2 L / 5 L / 20 L

Rotary Evaporator / AAS / ICP / Electron Microscope / Vacuum System / Semiconductor Equipment

Specifications for refrigerant types, power supply, and circulating fluid need to be confirmed individually.

Cooling for Rotary Evaporation

Rotary Evaporator Cooling

Low-temperature coolant circulates through the rotary evaporator condenser to support solvent condensation during evaporation, concentration, extraction, separation and related workflows.

FAQ

Start with the required coolant temperature and cooling capacity at that temperature.

No. The cooling capacity changes with operating temperature, so both values should be considered.

The current DW-YQ range includes 2 L, 5 L and 20 L configurations.

Depending on the model, circulation flow ranges from approximately 18 to 40 L/min.

The floor-type DW-YQ-20/20SJ provides 40 L/min flow, 15 m lift and up to 4200 W cooling capacity at room temperature.

Yes. Rotary evaporation is one of the primary applications listed for the DW-YQ series.

SJ models specify ethanol or antifreeze.

No. Refrigerant specifications vary by model, so the selected model should be confirmed before ordering. For example, the small SJ series specifies R404A, while DW-YQ-20/20SJ specifies R22.
