Cost-optimised for controlled room climate

Belimo room and system solutions encompass a complete program for the cost-optimised control of zones and individual rooms - in comfort zones as well as in industry, trade and sensitive work areas. After all, health, well-being and productivity greatly depend on room climate.

More comfort, improved working environment, maximum energy efficiency

Optimal actuator and control solutions for air flow control

Product range

VAV-Compact – efficient room control with just one device

Actuator, controller and sensor – the VAV-Compact is the economical solution for variable and constant volumetric flow systems in office buildings, hotels, hospitals etc. all in one device. Special rotary actuators of 5, 10 and 20 Nm as well as linear actuators with 150 N fit on volumetric flow units (VAV/CAV) of different sizes and types. VAV-Compact controllers can be controlled conventionally using analogue signals via BACnet, Modbus, KNX or via the Belimo MP-Bus.

When using a bus connection, an additional sensor can be connected to each VAV-Compact. The sensor signal is digitised and available as a data point.

The VAV retrofit product range is available to replace volumetric flow controllers on site in the volumetric flow unit (one-to-one replacement or function expansion for communicative variants).

VAV-Universal – maximum flexibility for increased requirements

The modular structure of the VAV-Universal controller product range with integrated differential pressure sensor enables the ideal combination of controller and damper motorisation. With this product range, individual solutions for all special applications in the field of ventilation can be created.

D3 - Flow (dynamic) suitable for comfort zone
M1 - Diaphragm (static) suitable for polluted air
M1R - Diaphragm (static) for room pressure control

CMV Apartment ventilation

The complete VAV control unit with air speed sensor, actuator and damper blade is optimised for pressure-independent VAV applications in controlled apartment ventilation. The integrated thermo-anemometric measuring system is designed to record even the slightest air velocities. This enables the energy-optimised operation of individual systems without sacrificing comfort.

Demand-controlled fans

Efficient fan control is a vital part of a modern and energy-efficient ventilation system. To achieve this, the required room volumes are measured by means of presence, temperature and air quality sensors and processed as setpoint value for the decentralised volumetric flow controllers. These in turn generate demand signals for the fans of the air-handling unit. Directly controlled EC fans are now increasingly being used for power control. 

Intelligent controls with fan optimiser function record the damper blade positions of the volumetric flow controllers via the bus system (BACnet, Modbus, KNX, MP-Bus) and use the evaluation as a demand signal for energy-efficient fan control.

Customer-specific products

These days, challenges in planning and on the construction site are difficult to solve using standard products, which is why customer-specific solutions are becoming increasingly important. We build the actuator you need – with the cable length, connector plug and parametrisation you specify. 

  • Different cable types and lengths with or without a connector plug. 
  • Product labelling with your customer information (e.g. where the actuator is to be installed in the building). 
  • Various mounting options (adapted to your installation situation on-site). 
  • Wide range of electrical and mechanical accessories. 
  • We take care of the parametrisation for you (e.g. adjustable running time, switching differential and bus parameters).
  • Function test, because Belimo stands for tested quality.

We offer a "complete carefree package" for your application.
