Low-temperature liquid circulation

The DLSB-5/30 is a 5 L refrigerated circulator that delivers coolant down to -30 °C for laboratory applications. It uses mechanical refrigeration with a brand-name compressor and a microcomputer controller that shows temperature on a digital display. The unit circulates liquid at up to 20 L/min with a lift of 4-6 m and maintains precision of ±0.2 °C. It operates on 110 V/60 Hz power.

Suitable uses and limits

This chiller suits labs that need a compact low-temperature bath for rotary evaporators, jacketed reactors, vacuum freeze-dryers or magnetic stirrers. It is not for users who require temperatures below -30 °C, reservoir volumes larger than 5 L, or a 220 V supply without confirming availability. Buyers needing higher cooling capacity at low temperature or different flow rates should look at other models.

Temperature range decides fit

The no-load minimum reaches -33 °C and the guaranteed working range stops at -30 °C with ±0.2 °C stability. If your process demands colder set-points or tighter tolerance, this unit will not meet the requirement.

Questions about this item

Does the DLSB-5/30 require a 110 V / 60 Hz mains supply to operate?

Yes, the unit is rated for 110 V / 60 Hz; 220 V / 60 Hz and 220 V / 50 Hz versions are also available on request.

Can I connect this chiller to a rotary evaporator or jacket reactor that I already use?

The circulator is designed to work with rotary evaporators, vacuum freeze-drying ovens, jacket reactors, magnetic stirrers and similar lab equipment.

How can I verify the chiller is running within its ±0.2 °C precision after installation?

The microcomputer controller shows the real-time temperature on its digital display, allowing you to confirm the reading stays within ±0.2 °C of the set point.
