01 – STEAM & THERMAL OIL
Thermal Oil Heater w. Burner
L-VTO is the line of industrial heaters / boilers with oil or gas-burner that heats up circulating thermal oil to very high temperatures.
Using these heaters / boilers is relevant for high temperature applications as an alternative to – for instance – steam and water. The high temperature using steam and water requires a corresponding high operating pressure which can be a challenge for many reasons.
In the L-VTO line of thermal oil heaters, a special heat transfer fluid (HTF) is used as heat carrier instead – and that means that you can achieve operating temperatures up to 310°C even at atmospheric pressure.
The HTF is either circulated one long tube that is winded-up in two coils forming the heater core and equipped with a gas or oil-burner.
All thermal oil heaters / boilers are widely customized to each specific task.
Technical description
Design according to PED 2014/68/EU & EN-standards. CE-marked and with full documentation.
Thermal oil heater models are made in different designs. This version is heated by the flame of a burner (oil, gas or combinations).
They are built up in a tube coil design i.e. one single tube winded up into two tube coils placed inside each other forming a combustion chamber with convection passes.
This gives a full 3-pass design ensuring high efficiency and lowest emission according to the regulations in EU.
The design comprises low-NOx burners and a required large combustion chamber volume. Available as both vertical and horizontal heaters.
All thermal oil heaters / boilers are individually designed for 24/7 heavy-duty operations.
