THE PROCESS OF ACQUIRING AIR PROTECTION TECHNOLOGY

The need to address pollutant emissions arises most often for the following reasons:

  • Conflicts with applicable air protection legislation (existing production or investment project)
  • Existence of a physically or morally obsolete or non-functional existing emission treatment system
  • Evaluation of the possibility of replacing an inefficient, usually not economically viable solution with a new technology

If this situation concerns you, please contact us.

Our experts will be happy to assist you and together guide you through all the necessary steps.

A well-defined demand is one of the determining conditions for developing an optimal solution.

This often underestimated step has a major impact on the quality of the subsequent technical design.

Our company has one of the largest and best-equipped emission measurement groups and, with the support of our own physico-chemical laboratory, we carry out pollutant emission measurements tailored to the needs of the technical solution.

The usual scope of documentation is production documentation of mechanical, electrical, MaR, construction (if it is current and required). In case of need and interest, we also provide documentation for building permits (including their processing).

The equipment is supplied and installed as a turnkey delivery by our own staff, who also provide training in the operation and maintenance of the technology.

The commissioning process comprises individual tests, comprehensive tests, commissioning of the test plant and then commissioning for permanent operation. This is completed with a guarantee measurement and the handover of the complete technical documentation.

The standard warranty is 24 months. Based on service contracts, we offer unlimited after-sales service for the entire lifetime of the equipment. This includes regular annual maintenance and preventive maintenance.

For operational service interventions, we equip the equipment with remote management, which minimizes the need for travel and significantly reduces service costs.

All servicing is provided by our own staff.

The result of this step is the elaboration of a proposal for an optimal solution according to the investor’s priorities (Capex/Opex, etc.), or the elaboration of solution variants for the subsequent process of selecting the technology and its supplier. It includes a price calculation prepared according to the needs and layout of the investor.

The usual scope of documentation is production documentation of mechanical, electrical, MaR, construction (if it is current and required). In case of need and interest, we also provide documentation for building permits (including their processing).

The production of the equipment is mostly carried out in the Czech Republic. Our products are supplied to domestic customers as well as abroad and are manufactured in accordance with the applicable European regulations and technical standards.

TYPES OF VOC ABATEMENT TECHNOLOGIES

Frequently Asked Questions (FAQ)

Edit Content

We offer a complete portfolio of technologies for reducing volatile organic compound (VOC) emissions:

  • Recuperative catalytic oxidation (RKO, KNV, KOJ)
  • Recuperative thermal oxidation (TNV)
  • Regenerative catalytic oxidation (RCO, RKNV)
  • Regenerative thermal oxidation (RTO, RTNV)
  • Zeolite rotary concentrator

 

All technologies are manufactured by ELVAC and supplied on a turnkey basis, including warranty and post-warranty service.

Edit Content

Recuperative catalytic oxidation (RKO) uses a catalyst to convert VOCs into CO₂ and H₂O at a lower temperature. The system is optimized for medium to high VOC concentrations (2–6 g/m³) and includes a heat exchanger, a heating chamber (gas/electricity), and a catalytic reactor.

Edit Content
  • Recuperative RCO has a single catalytic reactor with a heat exchanger, suitable for 2–6 g/m³ VOC.
  • Regenerative RCO uses ceramic honeycombs stored in layers in reactors, which alternately accumulate and release heat, targeting low and medium concentrations (0.2–3 g/m³). This makes it more energy efficient.
Edit Content

Regenerative thermal oxidation (RTO) is a system with 2–3 ceramic exchangers that accumulate heat and a combustion chamber with a gas burner. We recommend it for medium VOC concentrations (1.5–5 g/m³), especially if you want to minimize operating costs and utilize waste heat.

Edit Content

The zeolite rotary concentrator concentrates very low VOC concentrations (0.1–0.5 g/m³) from a high volume of air (tens to hundreds of thousands of m³/h). After VOC concentration on zeolite, the gas is transferred to the final oxidation unit (TNV, RTO, or RCO), achieving high efficiency even with low emissions.

Edit Content
  • Technical design with solution options and financial budget (Capex/Opex)
  • Manufacture of equipment mainly in the Czech Republic in accordance with European standards
  • Installation and operator training by our specialists
  • Commissioning, including comprehensive testing and warranty measurements
  • 24-month warranty and unlimited post-warranty service with annual maintenance and remote management.
Edit Content

The installation of the equipment itself usually takes 1–4 weeks (depending on the complexity and size of the installation). Comprehensive commissioning with warranty measurements and handover of documentation takes another 1–2 weeks.

Edit Content
  • Standard 6 hours per source
  • Up to 12 hours for more extensive or multiple parameters
  • Administration and report processing usually take an additional 1–2 days
Edit Content

We provide a 24-month warranty on all equipment. As part of our service contracts, we offer unlimited post-warranty service throughout the entire lifetime of the technology, including annual maintenance, preventive inspections, and remote management for quick resolution of any malfunctions.

Edit Content

Yes, for a quick and flexible solution, we offer a mobile recuperative catalytic oxidation unit that can be deployed immediately wherever there is an unexpected need to reduce VOCs.

Edit Content

Yes, our accredited and authorized emissions measurement laboratory provides technological and authorized emissions measurements tailored to each technology. This allows us to document the effectiveness of the installed system and compliance with legislative limits.
