When there is a demand for constant flow and constant head, a speed controlled pump can replace a throttle valve for adjusting the flow.
The speed can be adjusted between 25% and 100%.
This feature is especially beneficial in:
- Heat surfaces
- Cooling surfaces
- Heating systems with 3-way valves
- Air con. system with 3-way valves
- Chiller pumps
