Expansion vessel DPV 300 (for water) A2C2L51

Multifunctional expansion vessel DPV 300 for professional water installations

The DPV 300 expansion vessel is an advanced solution for water systems with a capacity of 300 liters, designed for professional installers and demanding end users. Equipped with a sealed butyl membrane and an insulated protective cover, it ensures reliable operation across a wide temperature range from -10°C to 99°C at a maximum pressure of 10 bar.

Technical parameters and construction

The device features a robust carbon steel construction with an external white epoxy coating. Dimensions of 1190mm height and 650mm diameter ensure optimal efficiency while maintaining a compact form. A pre-charge pressure of 2.5 bar guarantees correct system operation from the first startup.

The G1"1/4 threaded connection allows for easy installation in most standard water installations.

Applications and versatility

The DPV 300 vessel is a key component of professional water installations:

• Drinking water - CE certification guarantees safety for food contact
• Domestic hot water - resistance to high temperatures up to 99°C
• Heating systems - pressure stabilization and hydraulic shock damping
• Air conditioning installations - efficient operation at low temperatures
• Pressure boosting systems - pump operation optimization

An additional advantage is compatibility with water-glycol mixtures containing up to 50% glycol, which expands the application possibilities in heating systems.

Build quality and certification

The construction complies with CE directive requirements and the declaration of conformity with the essential safety requirements specified in directive 2014/68/EU.

The steel construction with epoxy coating provides excellent corrosion resistance and an aesthetic appearance throughout its service life. The insulated cover protects the membrane from mechanical damage and the influence of external factors.
