LVOBO DLSB Low-Temperature Refrigerated/Heating Circulator with Internal and External Circulation
The LVOBO DLSB series is a laboratory low temperature recirculating chiller for direct bath use and compatible external equipment. It combines PID temperature control, a stainless-steel reservoir, compressor refrigeration, and internal/external circulation in one system. Available bath capacities include 5 L, 10 L, 20 L, 30 L and 50 L, with model classes selected by the required minimum temperature. The external loop can support matched rotary evaporators, jacketed reactors, condensers, viscometers and other laboratory instruments, while internal circulation is intended for samples placed directly in the bath. For reliable model matching, buyers should confirm target temperature, heat load, working fluid, bath dimensions, flow, pump head, connections and local power supply before quotation.

The DLSB series combines an open stainless-steel bath with internal circulation and an external loop. Model selection should start from the working temperature, heat load, fluid, vessel dimensions and destination power supply.
PID Temperature ControlElectronic PID regulation supports routine constant-temperature operation across the selected model range. |
Internal & External CirculationUse the bath for direct sample temperature control or circulate temperature-controlled fluid through compatible external equipment. |
5–50 L Bath OptionsMultiple bath capacities support different sample sizes, vessel dimensions, circulation loads and laboratory workflows. |
Stainless-Steel BathDurable stainless-steel inner construction supports routine laboratory use, heat exchange and straightforward cleaning. |
Fully Enclosed CompressorIntegrated refrigeration architecture provides low-temperature cooling capability across multiple temperature classes. |
LCD Control PanelA clear digital interface provides direct controls for circulation, cooling, power and temperature setting functions. |
The LCD interface separates circulation, cooling, power and setting controls so operators can adjust the selected configuration without a complex menu sequence.
Before connecting an external load, confirm the inlet, outlet and drain arrangement together with tubing size, sealing method, working-fluid compatibility, circulation flow and pump head.
Internal circulation moves the working fluid within the reservoir for samples placed directly in the bath. Confirm the bath opening, tank depth, vessel dimensions and suitable working fluid before ordering.
The external loop can supply temperature-controlled fluid to compatible rotary evaporators, jacketed reactors, condensers, viscometers and analytical systems when flow, pressure, connection and heat-load requirements are matched.
Model-specific data for preliminary selection. Cooling capacity is shown as the supplied reference range. Final performance depends on ambient conditions, working fluid, heat load and configuration.

It is a laboratory temperature-control system that cools and circulates a working fluid inside a bath or through compatible external equipment.
Yes. External circulation can be used with compatible rotary evaporators, jacketed reactors, condensers and other laboratory equipment when flow, connection and heat-load requirements are matched.
The series includes minimum-temperature classes of -10°C, -20°C, -30°C, -40°C, -60°C, -80°C and -120°C, with an upper range of 99.9°C in the supplied model table.
The circulation medium must be selected according to the target temperature and equipment compatibility. Ordinary water should not be used directly below 0°C.
Select the bath capacity together with the required minimum temperature, heat load, flow demand, vessel dimensions and external equipment requirements.

The LVBO BO-DFY Low-Temperature Thermostatic Magnetic Stirring Reaction Bath combines controlled heating and cooling, magnetic stirring, and internal/external fluid circulation in one laboratory system. It is designed for research, material development, pharmaceutical R&D, chemical laboratories, and quality-control teams that need stable temperature conditions without adding a separate shaft-driven stirrer. PID control supports ±0.1°C temperature fluctuation under specified operating conditions, while the stainless-steel inner bath and LCD interface simplify daily use. Multiple capacities and model-dependent temperature ranges help distributors and end users match the equipment to different sample loads. Cooling capacity is adjustable within the listed range. Over-temperature protection, alarm, and automatic power cut-off support safer operation. Before ordering, verify the chosen fluid, voltage, process load, vessel size, and temperature requirement.
