Terminal units

Terminal units such as fan coil units, climate panels and induction units are particularly popular in HVAC systems for larger buildings. There are some good reasons for that; they don’t take up precious floor space, they can be accessed for service or maintenance, they are simple to connect to the HVAC system and they can be used for heating, comfort cooling, or both.

To achieve high indoor comfort of the heating and/or cooling provided by the Terminal units, it is important to have a proper hydronic balance, reliable control valves and accurate room temperature controllers. This is where Danfoss comes in.

Our Pressure-Independent Balancing and Control Valves (PIBCV) ensure proper system hydronic balance, both in full load as well as partial load conditions. Once equipped with a matching actuator, they function as control valves at the same time.
If both heating and cooling are required and a four-pipe system is used, our robust changeover valves provide a compact solution, eliminating separate balancing and control valves for heating and cooling.

We also offer the more traditional manual balancing valves and motorized control valves. This combination can be used where three-way control valves are used, and a constant flow system is achieved as a result.

Danfoss room thermostats offer a simple standalone solution to control the room temperature. They are connected to the control valves and ensure a stable room temperature and optionally fan speed selection and time scheduling.
