Built for sealed potable hot and chilled water systems in domestic and commercial settings, these Potable Water Expansion Vessels stabilise pressure by absorbing thermal expansion for safe, reliable operation.

A nitrogen pre-charge helps retain set pressure longer, while a single threaded steel connection with plastic insert provides a durable, non-flow-through design. Suitable for central heating, cooling and tap water applications (not for solar collector circuits).

• Nitrogen gas filling for longer pre-charge retention
• Single threaded steel connection with plastic insert (no flow-through)
• Potable use supports domestic hot/chilled water
• Heating & cooling compatible for sealed systems

Designed for long service life with broad operating limits and glycol tolerance for demanding installations.

Purpose-built for sealed systems, the Flamco Flexfiller 2160D (17393) combines an electronic pressure transducer with a user-friendly microprocessor to maintain minimum system pressure with precision.

This floor-standing unit delivers top-up flow rates up to 18 L/min via an 18 Ltrs internal break tank. Max pressure, 14.4 bar. Ideal for commercial, industrial and large domestic applications, it's available in single or twin-pump configurations and supports sealed LPHW/CHW systems (guide volume up to 300,000 Ltrs).

• Category 5 protection (Type AB weir overflow)
• MODBUS RTU integration; password-protected access
• 0.1 Bar incremental pressure setting; system fill mode
• Service reminder after 12 months

Finished in black (RAL 9005), the cabinet is powder-coated mild steel with WRAS-approved float, polypropylene break tank, brass/PP connections and braided flexhose/EPDM/copper pipework; valves are brass with PTFE seats.

Engineered for sealed systems, the FLAMCO Midi PSD 150D vacuum degasser (Pressure Step Degasser) strips dissolved gases to stabilise pressure and improve plant efficiency. Single pump.

The unit samples system fluid, isolates it and applies a full vacuum so dissolved air is released per Henry's Law, vents this to atmosphere, then returns deaerated water to the circuit. A digital processor automates the cycle with a turbo mode for rapid commissioning and a real-time status display.

• Automatic vacuum deaeration with turbo & normal intervals
• Digital control and real-time component status
• Password-protected settings; 0.1 Bar pressure steps
• Event logging and volt-free common fault output

Suitable for commercial, industrial and residential LPHW/CHW applications. Model guide volume: up to 50,000 Ltrs (larger variants available up to 300,000 Ltrs).

Designed for sealed LPHW/CHW systems, the Flamco PressDS Plus 2160D integrates pressurisation, vacuum degassing and on-demand dosing to keep system pressure stable, remove dissolved gases and blend the correct additive mix during top-up.

A compact, totally enclosed Twin Pump unit, it uses a digital processor to automate the sampleisolatevacuumventreintroduce cycle (with turbo mode for rapid commissioning). Top-up capacity is <18 L/min; an 18 Ltrs additive tank blends inhibitor at the point of fill. Guide system volume: up to 300,000 Ltrs.

• Category 5 protection (Type AB weir overflow)
• MODBUS RTU communications; password-protected access
• Mix ratios user-set from 150% via balancing valves
• Pressure setpoints in 0.1 Bar increments

Ideal for commercial plantrooms, the black (RAL 9005) enclosure includes sequential programming, system fill mode, pump-pulse, flood-protection routines and comprehensive event logging.

Flamco Flexcon Expansion Vessel - 110Ltr - Engineered for EN 12828 heating and chilled-water systems, this Expansion Vessel stabilises sealed system pressure by absorbing thermal expansion in LPHW/CHW applications.
