Lowara UKBETA200DS80/A Presfix Beta 280 Dual System

Lowara UKBETA200DS80/A Presfix Beta 280 Dual System

The Presfix Beta 280 dual pressurisation set brings the benefits of managing two independent systems from a single unit. The Presfix Beta 280 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.

The Presfix Beta 280 Dual system unit is supplied as twin pump sets with the pressure range 8.0 bar. 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. All the control features and specification are the same as the standard two pump Presfix Beta details.
