Description
Transcal™ N is a high quality mineral oil possessing low vapour-pressure characteristics as well as high levels of thermal stability, specific heat and thermal conductivity.
Application
Transcal N is recommended for non-pressurised, closed liquid-phase heating systems operating at bulk-fluid temperatures up to 320ºC, and a maximum film temperature of 340ºC.
Such systems are used widely in the food, construction, plastics, timber, oil and gas processing and on ships and where waste heat is extracted from flue gases.
