## Summary description

Reflex Refix DD 25 is an expansion vessel designed for domestic hot water (c.w.u.) systems. Rated for up to 10 bar and 70°C, this diaphragm-type vessel accommodates thermal expansion in potable hot-water circuits. It protects system components from pressure surges, reduces cycling of pumps and valves, and is suitable for residential and small commercial DHW installations.

## Long description

Reflex Refix DD 25 is a diaphragm-type expansion vessel designed for use in domestic hot water (DHW) systems. Rated for operation up to 10 bar and 70°C, this compact green vessel compensates for thermal expansion in potable hot-water circuits. The closed bladder separates the potable water from the precharged gas chamber, maintaining system pressure stability and helping to prevent pressure surges that can stress pipes, valves and fixtures.
Advantages
The Reflex Refix DD 25 reduces pump and valve cycling by absorbing volume changes as water heats and cools, which contributes to longer component life and quieter operation. Its diaphragm design minimizes contact between potable water and the vessel’s metal body, lowering the risk of corrosion and maintaining water quality. The vessel’s pressure and temperature ratings make it suitable for typical residential and small commercial DHW installations.
Suitable for
 Domestic hot water (DHW) systems in single-family homes
 Small apartment buildings and light commercial DHW installations
 Systems where prevention of pressure surges and reduced pump cycling is required
Key specifications
 Type: Diaphragm (bladder) expansion vessel for potable hot water

 Colour: green
 Capacity class: suitable for small domestic DHW circuits (25 nominal size)
How to use
Install the Reflex Refix DD 25 in the potable hot-water circuit according to applicable plumbing codes and manufacturer installation guidelines. The vessel should be mounted and connected to the system at a location where it can effectively absorb expansion, typically near the hot-water heater or DHW manifold. Verify that precharge pressure matches system requirements before commissioning and adjust if necessary. Regularly inspect connections and the vessel exterior for leaks or damage and ensure the system operates within the specified pressure and temperature limits.
Usage recommendations
Before installation, confirm compatibility with your DHW system and set the vessel’s precharge to the static system pressure or manufacturer-recommended value. Do not exceed the specified maximum pressure and temperature. Periodic visual checks and pressure measurements help ensure long-term reliable operation.
