50L Low-Temperature Circulator

The DLSB50/30 is a 50-litre refrigerated circulator that delivers coolant down to minus 30 degrees Celsius for laboratory processes. It suits chemists and technicians who need stable sub-ambient fluid for rotary evaporators, jacketed reactors or vacuum freeze-dryers. The unit runs on 220-volt 50-hertz mains power and includes a microcomputer controller with digital display for straightforward operation.

50-litre reservoir and cooling capacity

A 50-litre tank provides ample volume for extended runs without frequent refilling. The refrigeration system produces between 1801 and 3809 watts of cooling power depending on load, maintaining temperature within ±0.2°C. The pump circulates fluid at 50 litres per minute with a head of 10 to 12 metres, sufficient for most bench-scale glassware loops. At no load the bath can reach minus 32°C, giving a small margin below the rated set-point.

Compressor reliability and wooden-case shipping

Brand-name compressors and key components are selected for dependable long-term service in laboratory environments. Built-in protection safeguards connected precision equipment if coolant conditions deteriorate. The machine measures 840 by 690 by 1280 millimetres and is shipped in a wooden crate with a typical transit time of 7 to 14 working days. Alternative voltages such as 110-volt 60-hertz or 220-volt 60-hertz are available on request.

Questions about this item

Will the 50 L reservoir and 50 L/min flow rate overwhelm my existing rotary evaporator or jacket reactor?

The unit delivers up to 50 L/min with a 10–12 m lift; match your glassware’s maximum flow and pressure ratings before connecting.

How do I confirm the chiller is holding the set temperature within the stated ±0.2 °C precision after installation?

Watch the microcomputer controller’s digital display — it shows real-time bath temperature so you can verify stability at the target point.

Does the wooden shipping crate include the circulation pump, hoses and fittings, or must I source them separately?

The chiller arrives in a wooden case with the built-in pump; external tubing and connectors for your reactor or evaporator are not included.
