How it works!
High turbulenceTrue counter current flow pathLow foulingHighest heat transfer coefficients
High Efficiency
Surface Area = QU x LMTD
Q = Heat transfer dutyU = Overall heat transfer coefficientLMTD = Log mean temperature difference
= ( Thot in – Tcold out ) – ( Thot out – Tcold in )ln ( Thot in – Tcold out )
( Thot out – Tcold in )
