Small devices, big impact.
Innovations redefining comfort

State-of-the-art building automation is indispensable in generating good air quality and pleasant temperatures for the best possible room climates. But ideal air quality is not the only prerequisite for room comfort. Pressure ratios between supply and recirculation air must be maintained in rooms and air ducts. The ability to control individual room climates is all the more important. Reliable HVAC components from Belimo perfectly harmonise these influencing factors, ensuring room comfort and productivity at all times in different rooms.
Heating and cooling components in the central plant, air handling units, and terminal units for the room are fitted with sensors, damper actuators, and control valves which are networked with each other for the best sense of well-being in rooms. Our intelligent HVAC components deliver excellent air quality for the highest level of room comfort.

Our sensors – the foundation of comfort

The Belimo sensor range is a result of over four decades of experience, research, and focus on providing value-adding technologies to customers throughout the HVAC industry. The sensors’ unique design offers easy installation and seamless integration, resulting in reduced costs and optimal system performance. We offer a complete range of sensors with high accuracy and long-term stability, resulting in better indoor comfort. Our broad product portfolio provides sensors for measuring temperature, humidity, pressure, CO2, volatile organic compounds (VOCs), and flow in pipe, duct, and outdoor applications. Belimo serves as your single-source provider of HVAC field-level devices for any building project.

While there are guidelines for indoor air quality, situation variables such as room function, clothing, activity level of those in the room, and simply the very personal needs of room occupants vary greatly. The temperature of the room becomes more noticeable the longer one is in it. During the heating period, temperatures that range from 20 to 22°C (compared to 25 to 26°C in summer) are recommended at floor level. Excessively high or low humidity also has a bearing on well-being, productivity, and even health. Learn more about the influencing factors of thermal comfort.

Pressure-independent control valves for perfectly balanced room comfort

Pressure-independent (PI) control valves ensure that hydronic systems are perfectly balanced at all times, leading to increased comfort. The ball valve technology maximises energy savings of variable flow pumping systems while addressing unique control challenges. Watch the Belimo Talk below and learn more about the dynamics of a hydronic system and how to ensure that the building performance matches the design size of the valves perfectly. Belimo offers a series of pressure- independent (PI) control valves; from the PIQCV, a super compact PI valve, ePIV an electronic PI valve offering true flow measurement to the Energy Valve that optimises, documents and proves water coil performance.

Learn from Rodrigo: how to achieve a perfectly balanced hydronic system

Delivering the required flow in hydronic systems can be challenging with pressure changes. The Belimo Hydronic Simulator helps you understand the dynamics of a hydronic system with manual balancing and pressure-independent valves. Download the Belimo Hydronic Simulator™ as an Excel file and learn how to use the Belimo Hydronic SimulatorTM in the Belimo Talk taught by Rodrigo.

Variable Air Volume (VAV) actuators ensure perfectly balanced room comfort 

Another factor in occupant comfort is the velocity of air movement. When draughts are present (often in rooms where ventilation and air-conditioning systems are faulty), evaporative cooling increases on human skin, which can be unpleasant for many people. Air velocity is also important for room acoustics. Excessively high airspeeds at variable air volume (VAV) boxes and air outlets can cause distracting noise and whistling.
