Built for tight installs, the Flexfiller Mini 130D is a slim, wall-mounted, single pump digital pressurisation unit for sealed LPHW/CHW systems, using an electronic pressure transducer and microprocessor control to maintain minimum system pressure.

A 0.4 L/min low-flow top-up paired with a 2 Ltrs internal break tank suits small commercial or large domestic applications. Pressure is adjustable in 0.1 Bar steps across a 0.53 Bar range. Suitable for heating systems with expansion vessels ≤ 300 Ltrs or chilled systems with expansion vessels ≤ 50 Ltrs. Single or twin-pump configurations available.

• Digital control with electronic pressure transducer
• 0.4 L/min top-up; 2 Ltrs break tank
• MODBUS RTU integration; password-protected access
• Category 5 protection (Type AB weir overflow)

Finished in white (RAL 9003) and powered from 230V 50Hz 1ph, the Mini 130D adds flood-protection routines, event logging and a 12-month on-screen service reminder for straightforward commissioning and operation.

Built for EN 12828 heating and chilled-water systems, Flexcon Premium Expansion Vessels stabilise pressure by absorbing thermal expansion in sealed LPHW/CHW installations.

The range introduces a lightweight TPO (thermoplastic polyolefin) diaphragm on 12–35 Ltrs models, combining high flexibility with very low permeability. Using up to 50% less material cuts raw-material use and transport energy, while FSC-certified packaging further reduces CO₂ impact.

• Sustainable design — lighter TPO membrane; FSC-certified packaging
• Long service life — 15-year warranty and factory functional testing
• Low permeability — helps pre-charge hold for longer
• Nitrogen filled — limits corrosion and pressure loss vs air

Construction features include a zinc-plated steel clench ring that evenly clamps the diaphragm for a perfect seal, pre-coated vessel halves (no clamp-ring corrosion or thermal shock to the diaphragm), a countersunk nitrogen valve protected by a recycled-plastic cover plate, and a ribbed, preformed rolling diaphragm that resists sticking. An uncoated taper water connection thread eases watertight installation; the vessel is finished in a gleaming epoxy-powder coat.

Vessels to protect Flexcon expansion vessels on elevated temperature systems. The vessels are fitted in between the expansion vessel and the system return. System water flows from the installation into the top of the vessel. From the bottom of the vessel, significantly cooler water is fed into. Capacity 200 Ltr.
