Ultra-low temperature chiller

The HNZXIB DLSB-20/80 is a mechanical refrigeration circulator that delivers coolant down to -80 °C from a 20 L reservoir. It operates on 220 V/50 Hz mains power and provides a pump flow of 20 L/min with a lift of 4–6 m. The unit is designed to supply stable low-temperature liquid for laboratory apparatus such as rotary evaporators and jacketed reactors.

Suits labs needing -80 °C circulation

This chiller fits facilities that require precise temperature control at -80 °C with a 20 L bath volume and digital microcomputer display. It is not suited for applications that need larger bath volumes such as 30 L, 50 L or 100 L, nor for processes that demand temperatures below -80 °C such as -120 °C. Sites without 220 V/50 Hz supply should also consider other options.

-80 °C minimum temperature decides fit

The no-load minimum temperature of -82 °C and the rated range to -80 °C with ±0.2 °C precision determine whether this circulator meets the thermal requirements of the intended reaction or storage protocol.

Questions about this item

How often does the 20L reservoir coolant need replacing under continuous operation?

Coolant should be inspected regularly and replaced when contamination or degradation appears, as the unit includes protection for precise equipment under bad coolant condition.

What cooling capacity limit is reached first during sustained ultra-low temperature runs?

The refrigeration capacity spans 7828-230W, so the lower 230W figure becomes the limiting factor when maintaining -80°C continuously.

How much heat does the 1050×800×1000 mm cabinet reject into a 25°C room during all-day operation?

At full load the chiller draws up to 7828W, most of which becomes waste heat in the surrounding space, so adequate ventilation is essential.
