Product information

Description

Hydroland NP.CWU.24.IB is a 24‑litre diaphragm expansion/pressure vessel developed for domestic hot water (DHW) systems. Designed to absorb pressure fluctuations and compensate for thermal expansion in closed hot water circuits, this compact vessel helps stabilize system pressure, reduce pump and valve cycling, and protect piping and appliances from hydraulic shock.

Advantages

The diaphragm construction separates the water chamber from the pre‑pressurised air cushion, ensuring consistent performance and preventing waterlogging. Its compact 24 L volume is suitable for installations with limited space while providing effective pressure damping for domestic water heaters, boilers and solar thermal systems. Durable materials and a corrosion-resistant inner surface contribute to long service life under normal operating conditions.

Подходит для

  • Integration with domestic water heaters and boilers
  • Solar thermal DHW circuits
  • Closed hot water systems in apartments and single-family homes
  • Systems requiring reduction of pump/valve cycling and protection against water hammer

Key specifications

  • Nominal volume: 24 litres
  • Diaphragm type: elastomer membrane separating water and air chambers
  • Application: domestic hot water (DHW) closed circuits
  • Function: pressure fluctuation damping and thermal expansion compensation
  • Typical installation location: near water heater, boiler or in line with DHW circuit
  • Mounting: horizontal or vertical where space allows (follow installer guidance)

How to use

Install the expansion vessel in the cold-water line close to the water heater or boiler according to applicable plumbing and building codes. Pre-charge the air side to the recommended system pressure before connection and verify tightness after installation. Ensure the diaphragm is intact and not pre-compressed by overfilling; check the vessel pre-charge periodically and adjust as needed to maintain proper pressure balance. Routine inspection of connections and pressure readings helps sustain reliable operation.

Рекомендации по использованию

For optimal performance, match the vessel volume and pre-charge to the system working pressure and thermal expansion volume. Avoid exposure to freezing temperatures and mechanically isolate the vessel from vibration. When replacing or servicing system components, drain pressure as required and follow safety procedures. Consult a qualified installer for sizing and placement tailored to the specific DHW installation.
