Among baths, circulators, and recirculating chillers, why choose the latter? <a href=”/c/recirculators-and-chillers>Recirculating chillers deliver a flow of temperature-controlled fluid. They are enclosed circulators featuring robust cooling systems used for demanding continuous-use lab applications.

Recirculating chillers offer:

  • Temperature control from -10° to +80°C
  • Sealable reservoirs which permit open-loop and closed-loop use
  • Pumping capacities up to 15.5 L/min

In addition to many lab applications such as chemical, pharmaceutical, and food and beverage processing, chillers are used in industrial settings. These include:

Plastics: chillers cool the hot plastic that is injected, blown, extruded, or stamped. Chillers can also be used to cool down the equipment used in the manufacturing process.

Lasers: chillers cool down lasers and the power supplies used to power them.

Printing: chillers remove the heat generated by the printing rollers and also cool down the paper after it comes out of the ink drying ovens.

Machine tooling: chillers cool the spindle of the machine as it produces the part and cools the liquid being sprayed on part itself as it is being turned on the spindle.

    2. Cooling Capacity – 2.5 kW (@ 20 C)
    3. Fitting size : 3/4″ ID (Barbed) and pump connectors – G 3/4″. (This are requested considering the broader diameter which can be reduced later or changed)
    4. Temp range – -20 C to +40 C
    5. Pump flow rate – 40 L/min
    6. Pump pressure – 7.3 – 43.5 PSI

    I shall await for your reply.
