Sentera – your partner in HVAC control solutions

Sentera is your partner in HVAC control solutions

Intelligent, innovative and easy to use

Sentera is one of the leading manufacturers of control solutions for HVAC and ventilation systems. It all started with fan speed controllers. Until today, our product range covers different solutions to control AC or EC fan speed, manually or demand based. From simple - yet solid - transformer fan speed controllers, over electronic fan speed controllers to variable frequency drives. For manual control, we have a complete range of potentiometers and control switches!

Our product range has been further expanded with electric heater controllers, HVAC sensors, sensor controllers, power supply modules and distribution boxes.

From a simple manual control to a sophisticated building management system, we have the solution to it all. On top of that, our products are easy to use and easy to install – discover them on our products page!

Innovation is our drive! New technologies create new possibilities to increase the energy efficiency and the performance of ventilation systems. Our universal HVAC controllers communicate seamlessly with our HVAC sensors and fan speed controllers. They control air flows in function of your requirements. We can optimise your indoor air quality while realising significant energy savings.

Via the Sentera Internet Gateway, your smart ventilation system can be connected to the internet. It allows you to monitor all relevant parameters on a continuous basis. Discover typical combinations on our solution page!

From a simple fan speed controller up to an intelligent control solution that is able to optimise the supply of fresh air in function of your needs! Thanks to our exceptionally wide range of product groups, we can combine standard products and create a complete HVAC control solution. Single products and complete control solutions can be monitored and controlled via the internet.

Air quality management

How to monitor air quality? Indoor air quality or IAQ is not merely a matter of how the environment feels. Polluted indoor air also has a direct impact on our health and wellbeing. It's our mission to optimise your comfort, your indoor air quality and to contribute to your health in a positive way. The complete range of Sentera HVAC transmitters allow us to monitor, measure or control the following air parameters using а single device:


How to control fan speed? This topic has been our speciality for many years and until today, our product range offers different solutions, based on different technologies – each with their own, specific advantages.

  • Potentiometers and HVAC sensor controllers can control EC fans in a simple but reliable way.
  • Variable frequency drives provide optimal AC motor control for pump or fan applications.
  • Electronic fan speed controllers are easy to use and require minimum installation time. They offer a silent solution for infinitely variable AC fan speed control in various applications and industries.
  • Transformer fan speed controllers regulate AC fan speed in steps and are used in various applications: they control kitchen hoods, warm air heaters and even fans in agricultural applications.

How to control an air handling unit? A performant ventilation system requires a smart HVAC controller that is easy to use. Our HVAC controllers use the input of the HVAC transmitters to control the supply and extraction fans and to optimise the air flow on a continuous basis to create your perfect environment. The system can work standalone, it can be integrated in your BMS system or it can be connected to the internet for remote control and monitoring – the choice is yours!

A committed partner in HVAC


At Sentera, we believe that everyone benefits from practising and promoting ethical behaviour. Honesty and integrity foster a positive work environment that strengthens the reliance of all our stakeholders.

Our commitment is to demonstrating excellence in all spheres of our work and in our interactions with customers, suppliers, colleagues, partners and communities. In addition, we commit to exercising judgment, professionalism, rigour, self-discipline, perseverance and team spirit. We behave with integrity and moral correctness in everything we do and say, thereby earning and maintaining the trust and respect of customers, suppliers, colleagues, partners and communities.

As a global supplier of HVAC control solutions and fan speed control devices, Sentera has a policy of conducting business and operating within all regulatory guidelines. After reviewing our processes and consulting our carefully selected material suppliers, some of the products supplied by Sentera do contain one or more of the 3T1G - Tin (Sn), Tungsten (W), Tantalum (Ta), and Gold (Au), also known to be conflict minerals. Sentera does NOT directly purchase any of these minerals from the DR Congo or its neighbouring countries and does not know the source. Due to the complexity of the mineral supply chain, Sentera is unable to identify the origin for the minerals used in components and in our products. We are, however, asking our selected material suppliers to take reasonable due diligence in the supply chain to ensure that the minerals used are not sourced from conflict regions.

Environmental protection and the preservation of resources has been an integral part of the corporate policy at Sentera in its role as innovative and leading manufacturer of HVAC control solutions. In other words, we are committed to designing environment-friendly products and use environmentally compatible production processes. Sentera ensures that all legal directives concerning occupational safety and environmental protection are complied with during the production process. Our state-of-the-art products are designed in such a way that - when used as intended - users will not be subjected to any health hazards and the environment will not be polluted. Sentera has always been an environmentally responsible company and our products have been RoHS compliant since January 2005.
