Flamco Flexfiller Direct G4 Quiet pumpless pressurisation unit

The FlexFiller Direct G4 is a compact, wall-mounted, pumpless pressurisation unit designed by Flamco for maintaining pressure in sealed heating and cooling systems. It connects directly to a building’s mains water supply and automatically fills and maintains system pressure without the need for a pump.

Key features of the FlexFiller Direct G4 include:

Silent Operation: As a pumpless unit, it operates quietly, making it suitable for residential and light commercial applications.
Flow Rate: It offers a top-up flow rate of up to 14 liters per minute, depending on the mains water pressure.
Advanced Control System: Equipped with a user-friendly controller that displays operating and error conditions, it features microprocessor control, self-learning algorithms, and extensive data storage for analysis.
Communication Protocols: Supports MODBUS RTU and BACnet communication protocols via RS485, facilitating integration with building management systems.
Safety Features: Includes system safety valve monitoring, expansion vessel health monitoring, leak detection, and flood protection mechanisms.
Installation: Comes with flexible hoses for easy connection to the mains and sealed system, and a universal connection to the drain, fitting various pipe types.

This unit is suitable for systems with volumes up to 50,000 litres and allows pressure settings in 0.1 bar increments, providing precise control over system pressurization.
