Capillary Temperature Controller

Capillary Temperature Controller is designed for heating equipment that needs simple and reliable temperature regulation. With a sensing bulb connected by a flexible capillary tube, it detects temperature changes and automatically switches the heating circuit according to the preset temperature.

Its straightforward mechanical design makes it a practical choice for ovens, fryers, water heaters and various other heating appliances.

How Does a Capillary Temperature Controller Work?

 

The main components include a sensing bulb, capillary tube, temperature adjustment mechanism, and electrical contacts.

 

The sensing bulb is installed close to the area where temperature needs to be monitored. As the temperature rises, the liquid inside the sensing system expands and generates pressure. This pressure is transmitted through the capillary tube to the thermostat mechanism.

When the preset temperature is reached, the electrical contacts switch to control the heating element. As the temperature falls below the set point, the contacts return to their original position and allow heating to resume.

 

This mechanical control method does not require a separate electronic temperature sensor or control board, making it suitable for many conventional heating applications.

 

01

Reliable Temperature Control

Helps maintain the desired heating temperature with stable mechanical control.

02

Flexible Capillary Design

Allows the sensing bulb to be positioned according to the equipment structure.

03

Multiple Configurations

Available with different temperature ranges, capillary lengths, terminals and mounting options.

04

Wide Application Range

Suitable for ovens, fryers, water heaters and various heating equipment.

Capillary temperature controllers are commonly used in equipment where direct and reliable temperature regulation is required.

Commercial Ovens

In commercial ovens, the sensing bulb can be positioned inside the heating chamber while the thermostat body remains outside the high-temperature area. The controller switches the heating element according to the preset temperature.

Electric Fryers

For deep fryers, accurate temperature control is important for maintaining the desired oil temperature. A capillary thermostat can monitor the oil temperature and control the heating element accordingly.

Water Heaters

Capillary temperature controllers can also be used in water heating equipment. The sensing bulb detects water temperature and helps prevent continuous heating after the preset temperature has been reached.

Heating Equipment

They can be integrated into various industrial and commercial heating systems where a simple mechanical temperature control solution is preferred.

What is a capillary temperature controller?

It is a mechanical temperature control device that uses a sensing bulb and capillary tube to detect temperature and switch the heating circuit at a preset temperature.

Where are capillary temperature controllers used?

They are commonly used in ovens, fryers, water heaters, heating equipment, and other temperature-controlled appliances.

Can the temperature range be customized?

Yes. The temperature range and other specifications can be customized according to the application requirements.
