Thermostatic safety group ESBE VMB423 35-60°C CPF22 DN20 1.0MPa 31502500

Thermostatic safety group ESBE VMB423 – a compact protection for DHW systems.

The ESBE VMB423 safety group is a ready-made solution for protecting domestic hot water tanks. The set combines the functions of several elements, providing comprehensive protection and temperature regulation. This is particularly important in installations where precise control and protection against overheating or pressure drop are required.

Construction and application

The VMB423 group consists of a built-in check valve and connections for a safety valve and a vacuum relief valve (which must be purchased separately). The key element is a thermostatic mixing valve from the VTA320/VTA520 series, which allows you to set the desired hot water temperature in the range of 35-60°C. Thanks to this, regardless of changes in the temperature of the supply water, the user always has access to comfortable domestic hot water.

Advantages and benefits

• Compact design: The integrated construction saves space in the installation and simplifies assembly.

• Versatility: Suitable for use with various types of DHW tanks, both in domestic and commercial installations.

• Precise regulation: The thermostatic mixing valve ensures a stable water temperature, eliminating the risk of burns or discomfort associated with water that is too cold.

• Durability: The brass housing guarantees corrosion resistance and long device life. The clamping ring ensures a tight connection of installation elements.

• Safety: Provides effective protection against excessive pressure and vacuum in the DHW tank, protecting the installation from damage.

• Ready for installation: The set is delivered as a complete element, which simplifies the installation process and reduces the time required to start up the system.

• Siphon included: The presence of a siphon prevents water hammer and reduces noise during operation.
