The process of manufacturing of expensive and high-grade products especially pharmaceutical and special chemical products, include a great deal of heating or cooling procedures of materials to maintain a specific and desirable temperature. Though they are not produced in very large quantities, to get the desirable temperature the materials have to undergo numerous heating and cooling systems. Both heating and cooling work on the principle that heat always moves from warmer object to a cooler one, to facilitate this flow of heat, a medium is required which can be air, gaseous or any fluid (water or other oils). The medium must be flexible—with a wide operating temperature range, hence a liquid medium tends to be better than that of air or gaseous form. The industries which use heating and cooling systems in particular: Petroleum – for the crude oil production & processing, the best, efficient heating systems and services are a necessity in almost all its processes, which d
