A highly innovative engineering company


e2tech is a highly innovative engineering company that designs, develops, manufactures and implements state-of-the-art systems for the treatment of gas emissions and waste, as well as air conditioning and air filtration for the industrial sector.

Thermal Oxidation Systems

Industrial production processes generate Volatile Organic Compounds (VOCs) that must be treated to prevent their release into the atmosphere and thus reduce their polluting effect. Thermal oxidation systems are among the most efficient technologies for the treatment of (VOCs) gas emissions.

Air Handling Units (AHU)

Our solutions are based on modular designs that allow us to meet the most demanding market needs in the area of ventilation, air conditioning and air treatment in industrial facilities.

Activated carbon adsorption systems

We design air filtration systems based in activated carbon adsorption conceived for the retention of volatile organic compounds (VOCs) and the elimination of odours.

Solutions for the management of industrial gas emissions waste, air conditioning and ventilation.

Efficiency in air treatment

We offer solutions tailored to the needs of our clients and designed to reduce the environmental impact of industrial processes. We implement energetically efficient systems that are built using cutting-edge technologies.

We provide solutions within the industrial sector, mainly for the automotive, aeronautic, pharmaceutical, printing and packaging sectors.
