Marlotherm LH<\/h1>\n<\/div>\n
<\/div>\n
\n

Marlotherm LH is a low viscosity, synthetic, organic heat transfer fluid or thermal oil, for use in liquid or vapor phase in closed forced circulation systems, it maintains its reliability for a prolonged period under optimal maintenance conditions of the machinery.<\/h3>\n

In its liquid phase it is preferable to use it in non-pressure environments, due to its viscosity it is an ideal thermal oil for heating and cooling processes.<\/h3>\n<\/div>\n
