						Multitubular Heat Pipe® - A new concept in the heat pipe field In case of large heat transfer rates and high pressures the heat pipes welding on the separating plate is very difficult or impossible to perform because of the small distance between the walls of the tubes which is an essential condition for realizing high flowing speed and thus high heat transfer coefficients. This disadvantage is removed by applying the Multitubular Heat Pipe® concept.






						Multitubular Heat Pipe Preheater for Crude Oil in Tanks The multitubular heat pipe preheater for crude oil in tanks is a radical new approach to heating oil (crude oil, heavy fuel oil, etc.) stored especially in very large tanks. This concept has some important advantages in comparison with conventional preheaters.
						Independent Heat Pipes Preheater fo Crude Oil in Tanks The independent heat pipes preheater for crude oil in tanks is a radical new approach to heating oil (crude oil, heavy fuel oil, etc.) stored in tanks in that independent heat pipes are used to effect heat transfer from heating fluid to oil.This culminates in several distinct advantages.
					Heat Pipe Preheaters for Petroleum Products Manufactured by TRANSTERM®
						Oil Preheater for a 350 m3 Tank An independent heat pipes preheater for oil in tanks was manufactured in 1998 for a Romanian refinery. The unit is assigned to preheat the oil for certain processes.
						Crude Oil Preheater for a 20 m3 Tank An independent heat pipes preheater for oil in tanks was manufactured in 1999 for a Romanian crude oil exploitation field. The unit is assigned to preheat the crude oil coming out of a halfway process tank.
						Crude Oil Preheater for Process This heat pipe preheater was manufactured in 1998 for a Romanian crude oil exploitation field. It is manufactured using six large heat pipes made of carbon steel tubes, longitudinally finned. The unit was assigned to preheat the crude oil in halfway process tank.
						Heavy Fuel Oil Preheater for a Power Station This heat pipe preheater was manufactured in 1999 for a power station belonging to the Romanian electricity authorithy. It is manufactured using the Multitubular Heat Pipe® Vertical Concept and is assigned to preheat the heavy fuel oil just before entering the burners.
