Thermal fluid, whether synthetic or mineral thermal oil, is a first-class heating fluid for industrial processes. Thermal oil is generated in fire-tube boilers fired by either fossil or renewable fuels. As a heating medium in industrial processes, thermal fluid offers a number of thermodynamic advantages over steam: chief among them its high heat transfer capacity in liquid state, low system pressurisation and less corrosion wear on valve internals. Other performance advantages are the absence of blowdown, of changes of state through condensate or flash steam – which removes thermal shock altogether – and lower maintenance, since there is no feedwater and the circuits are closed.
Thermal fluid is a heating medium widely used for heating storage tanks, in process industries with heated presses (cardboard, board, plastics and rubber) and in chemicals and food. The boilers are fitted with safety and control valves built with temperature-resistant materials and packing (bellows), as are the rest of the valves in the circuit distribution. ARI ARMATUREN is a specialist company with extensive experience in manufacturing bellows sealed control valves, safety valves, manual isolation valves and strainers for thermal oil applications.
