High and Low Temperature Cooling Liquid Circulation Pump is an essential piece of laboratory and industrial equipment designed for precise temperature control. It integrates a refrigeration unit, a heating element, and a circulation pump into a single, compact system.

Its primary function is to provide a continuous flow of temperature-controlled liquid (such as water or oil) to external devices like reactors, spectrophotometers, or vacuum traps. The system can maintain a wide range of temperatures, from as low as -120°C to as high as +300°C, depending on the model and coolant used. This ensures stable thermal conditions for sensitive processes, experiments, or machinery that require rigorous heat management.

Key features often include a user-friendly digital interface for setting and monitoring the desired temperature, robust safety protections against overheating and low liquid levels, and high-efficiency circulation for uniform heat transfer. These pumps are vital in industries such as pharmaceuticals, chemical synthesis, biotechnology, and materials science, where accurate and reliable temperature control is critical for success, reproducibility, and safety.
