400l water heater SG(S) Tower Acu 400, without coil, enameled, rigid polyurethane foam, skay, vertical freestanding 22-408000N

The Tower Acu hot water tank is a solid solution for storing and heating domestic hot water, ideal for both domestic and industrial installations. Made of steel and enameled, it provides durability and corrosion resistance. Its design allows it to work with various heat sources – from central heating boilers to heat pumps or photovoltaic installations.

A tank with a capacity of 400 liters is particularly useful where larger hot water reserves are required, for example in public buildings, hotels or large housing communities. It can function as the main DHW tank or as a temperature stabilizer in extended heating systems.

• Efficiency and insulation: Energy efficiency class C and a thick layer of hard polyurethane foam minimize heat loss, reducing operating costs.
• Safety: EXTRA GLASS® ceramic enamel creates a durable protective barrier against corrosion, and a standard-fitted magnesium anode further protects the tank against external factors.
• Comfort of use: The main hydraulic connections located at the back of the tank facilitate installation and access to the installation during servicing. The possibility of installing a circulation pump ensures almost immediate access to hot water at every draw-off point.
• Versatility: The tank can be heated with electric heaters, which is a convenient solution especially in combination with a photovoltaic installation – allowing you to use your own energy to heat water.

The construction of the Tower Acu tank has been designed with easy installation and operation in mind. On the front there is a thermometer and the possibility of mounting an electrical kit "on the flange", and at the bottom a flange for connecting additional heat sources (diameter 180 mm). This allows it to be easily adapted to an existing installation or to create a new one, optimized for energy efficiency and comfort of use.
