Speed controlled operation
Speed control by means of a frequency converter is without no doubt the most efficient way of adjusting booster pump performance exposed to variable flow requirements. The speed control method results in a new Q/H curve at reduced head and flow.
Sprinkler alarm valve
An alarm valve prevents a reverse flow of water from the installation into the fire-pump room, but in case a fire sprinkler is activated (opened) due to fire, the alarm valve will open and permit water flow into the system.
Sprinkler distribution pipework
The sprinkler pipework distributes the fire suppression media into the building compartments. The pipe system design must be in compliance with the specifications described in the installation standard for fire sprinkler systems.
