Surface treatment and coating

Paint shops and surface-treatment operations generally handle large exhaust-air volumes with low concentrations of volatile organic compounds (VOCs). These emissions arise during coating application, drying and curing. When assessing a paint shop, Filtrační technika focuses on opportunities to reduce the air volume, thereby lowering operating costs and increasing energy efficiency.

Emission control technologies for surface treatment and coating:

Zeolite Rotary Concentrator

This system is ideal for treating large air volumes with low VOC concentrations. Exhaust air passes through a rotating zeolite adsorbent that efficiently captures the VOCs. A small stream of hot air then releases the captured substances in concentrated form, after which they are treated by regenerative thermal oxidation (RTO). This increases overall system efficiency and reduces operating costs.

Activated Carbon Adsorber

The adsorber uses activated carbon to capture VOCs from exhaust air. It is suitable for large air volumes and low pollutant concentrations. The activated carbon is periodically regenerated by a small stream of hot air, enabling continuous operation with low running costs.

Regenerative Thermal Oxidation (RTO)

RTO efficiently removes VOCs after they have been concentrated by a zeolite rotor or directly from exhaust air with higher concentrations. The exhaust air passes through a ceramic heat-storage bed into the oxidation chamber, where VOCs are oxidized at high temperatures. Process heat is recovered and used to preheat the incoming air, increasing energy efficiency.
