Overview
The Recirculating chiller DLSB-5/20A is a low-temperature liquid circulation unit designed to provide continuous cooling for laboratory and small-scale process applications. It uses a closed compressor with air cooling to remove heat from a circulating bath liquid, making it suitable for cooling reaction vessels, supporting chemical reactions at low temperatures, and storing chemical and biological products under controlled cold conditions. Temperature is managed through a digital display and microcomputer control, which keeps operation straightforward.

Applications and Integration
The DLSB-5/20A is intended for applications that require a stable supply of cold circulating fluid. It can cool reaction bottles, enable chemical reactions to be carried out at low temperatures, and assist with the low-temperature storage of chemical and biological products. The unit is also designed to work in combination with other laboratory instruments, including rotary evaporators, vacuum lyophilizers, and multi-purpose water circulation vacuum pumps.
For distillation and solvent recovery setups, the chiller pairs well with rotary evaporators such as the Rotary evaporator R-1020CE, where it provides the cold side needed for efficient vapor condensation. Larger evaporation tasks can be served by combining it with the Rotary evaporator R-1050CE. Laboratories that require an alternative cooling option may also consider the Recirculating chiller DL30-1000CE within the same equipment range.
Construction and Control
The chiller adopts air cooling driven by a closed compressor, delivering cooling intended to support consistent working efficiency. Operation is simplified by a digital temperature display and microcomputer control, allowing the set temperature to be monitored and adjusted easily. Internal components such as relays, protective devices, and capacitors are selected for quality, contributing to reliable operation across the rated working temperature range of -20 to 25 ºC. With a 40 L bath capacity, a 30 l/min pump flow rate, and 3/4'' hose connections, the DLSB-5/20A is configured to integrate with a range of standard laboratory fluid circuits.
