Pressurized expansion vessel PWB-20LH - horizontal, with 1 inch connection, for DHW systems, series: PressureWave

PressureWave pressure expansion vessels – reliability and durability in every system

Pressure diaphragm vessel PWB-20LH is an essential component in central heating and domestic hot water systems. Designed to operate in systems with thermal expansion, maintain pressure, and as an element of water towers and hydraulic shock absorbers. This tank, thanks to its solid construction and high-quality materials, ensures long-lasting and trouble-free operation. This is particularly important for both installers who value ease of installation and reliable operation, as well as end-users expecting comfort and safety.

Construction and materials – the key to longevity

The PWB-20LH vessel stands out with its well-thought-out design. The inner liner made of polypropylene effectively separates water from the tank walls, minimizing the risk of corrosion. The butyl diaphragm guarantees stable pressure and resistance to mechanical damage. The stainless steel connection ensures a tight and durable connection. Additionally, the double connection mounting and sealed air valve eliminate potential leaks. The whole is protected by a two-component polyurethane coating applied on an epoxy primer – this provides protection against moisture, UV radiation and corrosion.

Application and benefits – versatility in practice

The PWB-20LH vessel finds application in a wide range of installations:

• DHW systems: Provides stable water pressure and compensates for volume changes caused by temperature changes.
• Pressure maintenance systems: Maintains constant pressure in the installation, eliminating fluctuations and ensuring comfort of use.
• Water towers: Forms an integral part of a water tower, storing water under pressure and making it available on demand.
• Hydraulic shock absorption: Absorbs sudden pressure changes in the installation, protecting pipes and fittings from damage.
• Fire protection systems: Can be used as an element of fire protection systems, providing an adequate reserve of water under pressure.

Thanks to this, one vessel can be used both in home installations and in more demanding industrial or commercial systems. Moreover, PressureWave tanks have PZH certification and are covered by a 5-year warranty for maintenance-free operation – this is a confirmation of the highest product quality and peace of mind for the user.
