Main Features
These immersion heaters are mounted on the filling hole of the bulk containers of 1000 liters or more.
They simply land on this hole, thanks to a stainless steel cup that covers the thread, while maintaining a connection to atmospheric pressure. Their long non-heating part makes it possible to position the heating coil at the bottom of the container.
The surface load of the heating element is 3W/cm², so that it can be used in aqueous liquids as well as in oils and greases.
The stainless steel construction of the housing and of the heating element allows use in industrial and food processing environments.
In the internal access models the IP69K ingress protection allows the washing with hot water under pressure.
The temperature control is done in the center of the heating coil. A safety is installed on the top of the coil, to automatically turn off the heating when the decrease in the level of the heated product puts the coil in contact with the air.
These immersion heaters can be used alone in reheating, with or without insulating jacket, or in addition to heating jackets, in the latter case, they greatly reduce the heating time.
