Zilmet -10/+70°c Expansion Vessel

What Is an Expansion Vessel?

An expansion vessel, commonly referred to as an expansion tank, is an essential part of closed-loop heating or cooling systems. It makes up for changes in volume in water when temperatures change. When water is heated, it expands—without a vessel, pressure from this expansion can harm pipes, valves, or even boilers.

Key Features of the Zilmet Expansion Vessel

1. Wide Operating Temperature Range
The Zilmet Expansion Vessel is efficient in temperatures between -10°C and +70°C. This makes it suitable for both hot and cold environments and applicable to different types of HVAC systems.

2. High-Quality Membrane Technology
The vessel has a high-resistance rubber membrane separating the air and water spaces. This guarantees long-term performance and minimizes the requirement for regular maintenance.

3. Corrosion-Resistant Interior
In order to safeguard the interior surfaces from corrosion and rust, Zilmet applies new materials and finishes, enhancing the lifespan of the product even in wet or harsh environmental conditions.

4. Space-Saving and Compact Design
The vessel is compact given its capacity. It can easily be installed in small mechanical rooms or limited spaces, something particularly beneficial for urban dwellings or retrofitting.

5. International Standard Tested
Every Zilmet tank is subjected to extreme testing under European and international standards such as PED 2014/68/EU. You can rely on our consistent quality and safety.

Applications

Residential Heating Systems
Ideal for those homes with closed-loop boiler systems. It protects against overpressure through compensation of the expansion of water during heating cycles.

Solar Heating Systems
Zilmet tanks are suitable for solar water heating installations where temperature ranges may be more extreme.

Industrial HVAC Installations
Industrial facilities and commercial buildings utilize these vessels to stabilize pressure in large-scale and complex systems.

Chilled Water & Cooling Systems
Due to its low-temperature resistance, the vessel can also be utilized in cooling systems, avoiding vacuum conditions when the water shrinks.
