Why Sanitub?

    • Its bacteriostatic properties help maintain water quality, as they do not promote the development of biofilms, which are the source of diseases such as legionella.
    • It is completely impermeable to oxygen and external agents, preventing water from acquiring an unpleasant, unhealthy taste or smell. It does not release VOCs.
    • The drive flow is maintained in an emergency (e.g. fire)
    • Copper is a harmless material. The copper content in water is 2 mg/l at the consumer's tap output (according to Spanish Royal Decree 140/2003 of 07/02/2003).
    • Copper piping minimises energy installations, reducing heat loss and load.
    • Resistant to ageing.
    • The welded joint ensures a stable, durable connection.
    • It supports high pressures, so there is less risk of leaks and accidents.
    • No combustibles or gases are emitted.
    • Resistant to high pressures and high temperatures.
    • Copper piping is the best conductor of heat, making it ideal for the primary circuit.
    • It helps improve the energy efficiency of the system.
    • The fineness of the material.
    • Reddish in colour, which can be altered to obtain different finishes.
    • Rigidity, ideal for hiding cables in visible installations.
    • Easy to use, malleable.
    • Ideal for contact surfaces, thanks to its antibacterial properties that help prevent infections.
