What Is Heating Circulators?

What Is Heating Circulators

Heating circulators is closed water-cooling high temperature circulator providing cooling water with constant temperature, constant current and constant pressure.

Heating circulators heat the materials in the supporting reaction vessel through the heat transfer fluid outputed by the circulating pump.

Heating circulators is suitable for jacketed reactor, chemical pilot reaction, high temperature distillation, semiconductor industry, etc.

What Are The Types Of Heating Circulators?

Types Of Heating Circulators

Here is the truth:

Heating Circulators has different types based on the glass reactor’s volume.


Heating Circulators designed to work with glass reactors so it need to match with glass reactors specification.

The common types of Heating Circulators is SY-20-250 Heating Circulators, SY-50-250 Heating Circulators, SY-100-250 Heating Circulators and more.

Here we will explain them in details.

How Does Heating Circulators work?


Heating Circulator uses heat transfer oil as the medium and carrier.

It is Driven by the circulating pump, the heat transfer oil quickly absorbs and takes away the heat released by the electric heater and at the same time raises its own temperature.

It flows through the heat-using equipment, and after absorbing heat and cooling down, it flows back to the circulating pump and returns to the heater for reheating.

In such a circulating flow, the temperature of the thermal equipment is increased, and the heating process requirements are automatically met.

How to Choose Heating Circulators?

How to Choose Heating Circulators

Do you want to know what types of heating circulator to choose for your glass reactor?


Heating Circulator is mainly designed for glass reactor to make the synthetic reaction.

A reliable synthetic heating circulator supplier will confirm with you the following factors to help you find suitable type.

Glass Reactor Capacity

Here is the truth:

You need to know the capacity for your glass reactor when choosing heating circulators.

The larger capacity glass reactor will require larger flow for the heating circulator and you need to pay more money for it.

Instead, you just need to pay less if you choose a smaller one.

Temperature Range for Heating Circulator

This is another important factor about choosing heating circulator.

You should know what temperature degree you need before buying heating circulator. 

The highest temperature for glass reactor is 200℃ and it is recommend to choose heating circulator meeting this temperature range.
