What this chiller does
The HNZXIB DLSB-5/10 is a 5 L refrigerated circulator that delivers coolant down to -10 °C with ± 0.2 °C precision. It suits laboratories running rotary evaporators, jacketed reactors or vacuum freeze-dryers that need stable sub-ambient temperatures.
Check before ordering
The unit requires a 220 V 50 Hz supply; 110 V 60 Hz and 220 V 60 Hz versions exist but must be confirmed before purchase. Ambient conditions should stay near 25 °C and 60–80 % humidity, and the 500 × 370 × 540 mm footprint needs clear ventilation space.
Behaviour under load
At no load the bath reaches -15 °C; refrigeration capacity spans 1328–319 W depending on set-point. The pump circulates at 20 L/min with 4–6 m head, maintaining flow during extended reactions without short-cycle pressure drops.

Questions about this item
What comes in the box with the DLSB-5/10 chiller and what must I source separately?
The unit ships in a wooden case and includes the 5L chiller with built-in circulation pump, microcomputer controller and digital display. You must supply the 220V/50Hz power connection, coolant fluid and any tubing or fittings to link it with reactors, rotary evaporators or other equipment.
Should I choose the 5L -10°C model or one of the larger capacities and lower temperatures listed?
Choose the 5L -10°C model when your application needs up to 5 litres of coolant at -10°C with 20L/min flow and 4-6m lift. Larger reservoirs (10L to 100L) and lower temperatures (-20°C to -120°C) are separate models for higher heat loads or deeper cooling.
What does the 1328-319W refrigeration capacity mean for real-world cooling performance?
It indicates the chiller can remove between 319W and 1328W of heat depending on the coolant temperature, with a no-load minimum of -15°C and a controlled range of -10°C at ±0.2°C precision when ambient conditions are 25°C and 60-80% humidity.
