Enhancing Comfort and Efficiency with Thermal Actuators in Intelligent HVAC Systems


In today's rapidly evolving world, the demand for energy-efficient and smart solutions in the HVAC (Heating, Ventilation, and Air Conditioning) industry has grown exponentially. Among the key components driving this shift towards intelligent systems is the versatile and indispensable thermal actuator.


Thermal actuators have become a crucial part of modern heating and cooling systems, as they offer precise temperature control and fluid regulation, leading to enhanced comfort and energy efficiency. These devices are widely employed in various applications, including underfloor heating, ceiling radiant heating and cooling systems, air conditioning, and radiator heating systems.

One of the most significant advantages of thermal actuators lies in their ability to respond promptly to changes in temperature. When combined with room thermostats or other electrical switches, these actuators automatically adjust controlled loops to maintain a desired temperature, ensuring a comfortable living or working environment.


At SMLG, we take pride in offering two comprehensive heating control systems that cater to your preferences and needs. The first option is our wireless control automation system, where wall thermostats communicate with the control terminal block via radio waves, providing seamless and convenient control of your HVAC system.

For those who prefer a more traditional setup, we offer a wired automation system that requires the installation of wires connecting individual components. This robust and reliable system ensures efficient and accurate temperature regulation, leaving you with peace of mind.

Our range of thermal actuators includes both 230V and 24V versions, designed for either normally closed or normally open operation. With a power consumption of only 2W, these actuators are energy-efficient and environmentally friendly.

Equipped with an impressive force of 100±10N and a stroke of ≥4mm, our thermal actuators deliver precise and reliable control of fluid flow or temperature adjustments. They boast a protection grade of IP54, ensuring their durability and suitability for various indoor environments.

In line with industry standards, our thermal actuators comply with EN 60730 regulations, guaranteeing their performance and safety. The adaptability of M30x1.5mm/M28x1.5mm makes them compatible with different heating and cooling systems, providing versatile solutions for your specific needs.

The closing and opening time of these actuators is swift, taking only 3-5 minutes, resulting in efficient and responsive temperature control.


To maximize longevity and reliability, our thermal actuators are constructed using high-quality materials, such as PA66+30%GF housing, ensuring robustness and stability even in demanding environments.

Embrace the future of intelligent HVAC systems with SMLG's cutting-edge thermal actuators. Enjoy optimal comfort, efficiency, and control, all while contributing to a more sustainable and energy-conscious living environment.
