For use in ventilating and air-conditioning systems for water-side terminal units in closed circuits, e.g. induction units, fan-coil units, small reheaters and small re-coolers.
- 2-pipe systems with 1 heat exchanger for heating and cooling
- 4-pipe systems with 2 separate heat exchangers for heating and cooling
In closed-circuit heating systems, e.g.:
- Separate floors in a building
- Individual rooms
- Floor heating
