Product information

Description

The Afriso safety group BSB Nmax UDT for domestic hot water (DHW) systems is designed for installations with a thermal rating up to 111.5 kW. It integrates a safety relief valve factory-set to 6 bar and provides a dedicated connection for a diaphragm expansion vessel. The assembly protects potable hot water circuits from overpressure, permits controlled pressure relief and simplifies adding an expansion vessel in residential and light-commercial boiler or heater installations.

Advantages

The unit combines pressure safety and expansion vessel connection in a single compact assembly, reducing installation time and mounting complexity. The integrated relief valve set to 6 bar offers reliable overpressure protection for DHW circuits, while the dedicated expansion vessel connection ensures correct pressure buffering and system stability. The construction is suitable for potable water use and for typical hot water system operating conditions in homes and small commercial premises.

Suitable for

  • Residential domestic hot water installations
  • Light-commercial DHW systems in small buildings
  • Boiler and water heater protection where a 6 bar relief setting is required
  • Systems requiring connection of a diaphragm expansion vessel for pressure buffering

Key specifications

  • Rated thermal capacity: suitable for systems up to 111.5 kW
  • Safety relief valve setting: 6 bar (factory-set)
  • Includes a dedicated connection for a diaphragm expansion vessel
  • Designed for potable domestic hot water applications
  • Compact assembly suitable for wall- or boiler-mounted installation in residential and light-commercial settings

How to use

Install the safety group in the cold-water feed or on the DHW circuit according to local plumbing codes and the boiler or heater manufacturer’s instructions. Connect the relief valve outlet to a safe discharge point or pipework that conforms to applicable regulations. Fit the diaphragm expansion vessel to the dedicated connection using appropriate fittings and ensure the vessel pre-charge pressure matches the system requirements. Commission the system by filling, venting air, and verifying relief valve operation at the 6 bar setting.

Usage recommendations

Regularly inspect the relief valve and expansion vessel connection for leaks and corrosion. Test the relief valve operation during initial commissioning and as part of scheduled maintenance. Ensure water quality and system pressure are within acceptable ranges for potable DHW systems to maintain reliable operation and longevity.
