High temperature circulation tank

High temperature circulation tankIt is a laboratory equipment that achieves precise temperature control through circulating heat transfer media such as thermal oil or water, and is widely used in fields such as chemical engineering, pharmaceuticals, biotechnology, and materials science. Its core function is to provide a stable heat source for reaction vessels, rotary evaporators, extraction devices, etc., and support experimental operations such as high-temperature reactions, distillation, and drying.

Advantages of high-temperature circulation tank:

Efficient heating: Using stainless steel heating tubes immersed in the medium, the thermal efficiency is high and the heating rate is fast (usually 10-30 minutes to reach the set temperature).

Precise temperature control: PID intelligent temperature control system, temperature control accuracy can reach ± 1 ℃, supporting ± 0.1 ℃.

Safe and reliable: a fully enclosed circulation system equipped with an expansion container to prevent medium evaporation or oxidation; Solid state relay control circuit, contactless, no open flame.

Multi functional extension: Supports internal and external circulation modes, can connect various experimental equipment, and adapt to different viscosity thermal oil (below 500 ℃ · S · t).

Temperature management is achieved through a closed-loop system of "heating circulation temperature control":

Heating stage: The electric heating tube is directly immersed in the heat transfer oil, converting electrical energy into thermal energy and rapidly increasing the temperature of the medium.

Cycle stage: The high-temperature magnetic pump drives the flow of the medium, forming forced convection to ensure temperature uniformity in the tank.

Temperature control stage: The temperature sensor monitors the temperature of the medium in real time, feeds back to the PID controller, dynamically adjusts the heating power, and maintains the stability of the set value.

Key design:

Expansion container: isolates the main circulation system from the outside world, buffers the volume expansion caused by temperature changes, and prevents medium leakage.

Double layer insulation structure: Insulation cotton is filled between the inner liner and the outer shell to reduce heat loss and improve energy efficiency.

Characteristics and Innovation of High Temperature Circulating Tank Technology

Temperature control system

PID algorithm: By optimizing proportional, integral, and derivative parameters, temperature overshoot is reduced and stabilization time is shortened.

Multi mode control: supports local/remote control, programmable settings for heating rate, constant temperature time, and other parameters.

Circular system
