Product Catalog

Low temperature heat transfer fluid series products

The MAXTOP Low temperature heat transfer fluid series products (MTLT) series products are developed based on ultra-low pour point and highly stable synthetic materials as base oil, combined with self-developed MAXTOP heat transfer fluid composite additives, and through multiple patented formula technologies and self-developed ultra-long-term anti-coking test technologies that are subject to both low and high temperatures as well as oxidation.

They feature extremely low low-temperature fluidity, with no semi-solid or solid substances precipitating at low temperatures, smooth low-temperature fluidity, and insignificant viscosity increase at low temperatures.

The MAXTOP Low temperature heat transfer fluid series products(MTLT) series products are available in five models: MTLT-65, MTLT-75, MTLT-90, MTLT-105, and MTLT-115.
