Hitherm LT Rvn no : 1

Heat transfer fluid based on paraffinic base stock

Description
Hitherm LT is a low viscosity heat transfer fluid intended for use in applications that require liquid phase heat transfer. It can be used in non-pressurized or indirect systems and possesses excellent seal compatibility. Its excellent thermal and oxidation stability provides long service life and clean heat exchanger systems.
Applications
Hitherm LT is recommended for use in heat transfer systems where fuel oil, gas or electricity is used to heat a fluid transferring heat to the point of application. In closed systems, Hitherm LT has an optimum maximum use temperature of 250 °C (maximum bulk Tª).
Benefits

Excellent thermal efficiency and stability
Long oil life
Excellent rust and corrosion protection
Ease of pumping and circulation
Minimized sludge and deposits
