Constructed with a robust steel exterior, the HW 18L diaphragm DHW vessel features a powder-coated finish that enhances its durability and resistance to wear. The vessel is equipped with a unique diaphragm mounting system designed to significantly reduce the risk of leakage where the flange meets the tank, ensuring a secure and stable connection.

With dimensions that accommodate the constraints of compact spaces, this expansion vessel is suitable for installation in utility rooms or bathrooms with limited area. The compact size does not compromise its functionality or capacity, making it an efficient solution for domestic hot water systems.

The internal components that come into contact with water are treated with a protective layer to prevent corrosion. This attention to detail extends the lifespan of the vessel and maintains its performance over time. The vessel has a connection size of 3/4 inch, which is a common standard for ease of integration with existing plumbing systems.

The product's identification number, 5902188411447, ensures that customers can reference and verify the specific model for their needs. The use of ottone in the construction further signifies the quality and attention to detail in the manufacturing process.
