Questa \u00e8 la classica domanda che mi viene posta almeno due o tre volte la settimana…\u00e8 meglio uno scambiatore di calore<\/a> a fascio tubiero o uno scambiatore di calore a piastre?<\/p>\n

Scartabellando fra i miei documenti ho trovato una sorta di tabella che avevo creato allo scopo, da lasciare ai clienti, con le motivazioni che permettono di valutare un tipo di soluzione o un’altra.<\/p>\n

Ovviamente tutto \u00e8 discutibile e passibile di interpretazione personale, ma sicuramente quanto c’\u00e8 scritto \u00e8 realistico.<\/p>\n
