Mecanica group heat transfer oils are high-performance lubricants for use in closed and open, cold-oil sealed, indirect heating and cooling systems.
Mecanica group heat transfer oils may help:
FEATURES AND BENEFITS

Features |
Advantages and Potential Benefits |
|
High resistance to thermal cracking and decomposition |
Free from sludge and coke deposits and minimum interference with heat transfer capability and minimized maintenance needs |
|
Excellent thermal properties |
High heat transfer rates and improved operating efficiency and lower operating costs |
|
Good thermal and oxidative stability |
Long trouble free service life and reduced downtime |
|
Good low temperature fluidity |
Easy starting of cold systems |
Application Considerations:
Mecanica group heat transfer oils should not be mixed with other oils since this may impair the excellent thermal and oxidation stability resulting in a change in other properties, and complicate analyses aimed at determining useful oil life. If the oils are used above their recommended maximum temperatures, vapor lock may result unless the system is designed to operate at the higher temperature by pressurizing with an inert gas such as nitrogen. At higher temperatures, fluid life will be shortened because the rate of thermal degradation which increases markedly as temperatures rise above the recommended limit. In well-designed systems the temperature of the oil film surrounding the heating element should be about 15ºC to 30ºC above the bulk oil temperature. If higher than this, the service life of the oil may be shortened and sludge and coke may be deposited which would interfere with the heat transfer rates.
As with other mineral oils, Mecanica group heat transfer oils should be used only in systems with forced circulation. Systems that depend on convection for circulation of the heat transfer medium do not provide a rapid enough flow to prevent local overheating and rapid deterioration of the oil. Further, these oils are not recommended for use in open systems where hot oil is exposed directly to the air.

Handling health & Safety :
Lubricants consisting of highly refined mineral oils with specification additives. In normal conditions of use, this lubricant presents no particular toxic hazard. All lubricants, of any kind should be handled with great care, particularly avoiding can contact with the skin.
Prevent any splashing, and keep away from combustible materials. Store under cover and away from any risk of pollution. Dispose off the used oil correctly; don’t pour down drains, into watercourses or the soil.
