ElectricalLY-HEATED RTO
Very High VOC Elimination
with High Thermal Efficiency
Tecam’s Electrically-heated RTO
Due to the current world situation, energy transition and taking into account the European Union objectives, recently there has been a shift in the demand of how companies want to heat up the oxidation chambers of their Regenerative Thermal Oxidizer (RTO) systems for Volatile Organic Compounds (VOC) emissions removal at their production plants.
The trend has gone from burner-powered to electric-powered or to other forms of power, therefore flameless, and therefore without any NOX emissions derived from the burner, for a greener output.

You can always count on tailor-made solutions with Tecam and, where necessary, the development of specific components, software and/or materials. Our technicians engage with every project, using their expertise and knowledge to design customised equipment for each case and customer.
No matter how big or complex the problem, Tecam is the technology partner that will provide you with the solutions you need at all times.
The advantages of Tecam Electrically-heated RTO equipment
- Very High VOC elimination.
- High thermal efficiency.
- Once it reaches operating temperature, the system runs on auto thermal mode, with zero electricity consumption.
- No flame and therefore no NOx associated to combustion.
- Reduction of CO2 emissions, zero if renewable energy is used.
- Equal features and performance as Tecam conventional RTOs.
- Less noise around the equipment, due to the lack of a burner fan.
- Easier to do the installation and commissioning.
- Low operating costs.
- Simple and robust design.
- Almost no maintenance required.

How Electrically-heated RTO technology works
RTO equipment usually works with burners that use gas or fuel to heat up the oxidation chamber during start-up so that oxidation of VOCs can take place.
In the case of flameless RTOs, there is no burner and therefore no flame and no NOX emissions generated. The oxidation chamber gets heated up via some electrical resistances placed inside.
- During start-up -> the electric resistances will work at 100 % to be able to heat the RTO oxidation chamber up to the required temperature (eg. 850 ºC, 1100 ºC).
- During operation -> the consumption of electricity will depend on the VOC concentration at the inlet and its calorific value. If the concentration is above the autothermal point, resistances will turn off. Otherwise, if the concentration is lower than this point, the thyristors will modulate the resistances power to maintain the oxidation chamber temperature at the required temperature (eg. 850 ºC, 1100 ºC) to guarantee the oxidation of VOCs.
