Lowara Presfix Beta 280 Dual System (Max Fill Pressure 8 bar)
Description
Lowara Presfix Beta MK 2 280 Dual System (Twin pump, Max Fill Pressure 8.0 bar)
Presfix Beta dual pressurisation sets bring the benefits of managing two independent systems
from a single unit. The unit contains two individual display screens, so each system can be controlled
and monitored separately providing both systems operate at the same fill pressure which should
generally, be the case as the fill pressure is based on the building static height.
All other set points can be independently set for each system.
All Presfix Beta Dual system units are supplied as two pump sets
Each pump is available to both systems, so each system has a duty and standby pump available to it.
If one pump fails, then the standby pump will be available to both systems.
