Description

Trebles Flyvar is a variable speed drive package designed to optimise pump performance and maintain constant pressure within booster systems (variant dependent).

Typical applications

Variable-speed pump control
Energy optimisation
Booster set retrofits

The Trebles FLYVAR cold water booster range is designed to provide responsive, energy-efficient pressure boosting in a compact arrangement.

The single-pump configuration works with a variable speed drive to maintain stable pressure while keeping operation smooth and quiet. Set pressure can be adjusted easily through the inverter controls, which also display a live system pressure reading.

By mounting the inverter directly on the pressure vessel, there is no need for separate mounting brackets. This keeps the FLYVAR set light, compact and well suited to installations where available space is limited.

Real-world product applications

Boosting water pressure to multiple outlets in a building
Maintaining stable pressure where demand varies
Supplying water from storage tanks to distribution pipework
Supporting general water supply and transfer systems
Assisting with pressure control in utility installations
