These are high performance products designed for heat transfer in Textile, Pharmaceutical, Chemical and Processing Industries, equipped with indirect or secondary heating systems. They possess excellent resistance to thermal cracking and chemical oxidation and are non-corrosive and non-toxic. They possess high specific heats and thermal conductivities that provide good heat transfer efficiency and their viscosities are such that they can be pumped readily at both start-up and operating temperatures.
PALTHERM Heat Transfer Fluids are formulated from very stable high viscosity index base oils, coupled with a low pour point and fortified with high temperature oxidation inhibitors.
Recommended for use in closed, forced circulation with indirect or secondary heating systems, equipped with expansion tanks. The temperature of the oil film surrounding the heating element should be about 15ºC to 30ºC above the bulk oil temperature. Higher than this may lead to deposit of sludge and coke which would interfere with the heat transfer rates and also shorten the service life of the oil.
PALTHERM-500 and PALTHERM-600 grades are suitable for heat transfer up to 290ºC and 310ºC respectively.
These oils are not recommended for use in open systems where hot oil is exposed directly to the air. If they spray or escape from leakage points, hot oils may spontaneously ignite.
Health: This product is not expected to produce adverse effects on health when used for the intended application. However prolonged or repeated skin contact with this oil is injurious to health. Clean properly with soap and water. Environment: Lubricant should not be disposed in drain, soil and water. To be disposed through licensed/authorized collector of lubricants only.
