Caleffi 522 - Manual (Page 2)

As misturadoras termostáticas série 520 e série 522 são utilizadas
nas instalações de produção de água quente para uso
higiénico-sanitário, com termoacumuladores. A sua função é manter
constante, no valor seleccionado, a temperatura da água misturada
enviada à utilização, mesmo se a temperatura da água contida no
termoacumulador variar.
De thermostatische mengventielen van de serie 520 en 522 worden
toegepast bij sanitaire warm water installaties uitgerust met
warmwaterboilers. Zij zorgen ervoor dat de temperatuur van het
mengwater constant blijft op de ingestelde waarde wanneer de
temperatuur van het water in de boiler varieert.
