Maintenance of RTO & RCO systems

Solutions for energy and environmentally optimal operation.


Solutions for periodic and general maintenance of RTO & RCO systems.


During the operation of regenerative post-combustion systems (RNV / RTO), combustion residues are deposited on the ceramic elements of the honeycomb. Loading deposits leads to a reduction in the capacity of RTO & RCO systems. Therefore, the honeycombs need to be cleaned regularly and replaced if necessary.


  1. paint shops (incineration of base varnishes …),
  2. production of polyurethane foam (pulverization of release agents),
  3. production of batteries (manufacture of electrical circuits),
  4. cement plants (NO deposits in kilns and exchangers …).


  1. volatile organic compounds (VOCs),
  2. ammonia (NH) 3
  3. hydrogen sulfide (HS) 2
  4. polycyclic aromatic hydrocarbons
  5. nitric oxide (NOx),
  6. polychlorobenzene oxide (PCDD / F),
  7. dust,
  8. carbon monoxide (CO),
  9. hydrogen cyanide (HCN),
  10. carbon disulphide / carbon sulphide (CS2 /

Advantages - maintenance of cape and rco

Up to 30% better energy efficiency of RTO & RCO systems and lower emissions / emissions.

REDUCE ENERGY CONSUMPTION: multi-stage blowing and non-abrasive cleaning process ensures up to 30% better flows and energy efficiency

WE FOLLOW STANDARDS AND PROTOCOLS: all our maintenance work and procedures are in accordance with the standards and protocols of device manufacturers and our customers

WE ALSO CLEAN INACCESSABLE PLACES: we have developed our own system for cleaning inaccessible places, which are inspected with a camera after the procedure

Manual cleaning (above) and system for cleaning inaccessible places in low-cross combustion chambers (below).

NO DAMAGE TO EQUIPMENT: we provide completely safe maintenance interventions, no damage to ceramic cores and equipment (flaps, impellers, electricity, tires, …)

WITHOUT WATER AND CHEMICALS: we use a completely dry cleaning process to clean the incinerators, which allows you to start the devices immediately after the maintenance procedure.

SHORT STOP TIME: we organize project work in 2- or more shifts and thus ensure the shortest possible shutdown time of equipment

Our services

Maintains RTO & RCO systems in the best possible shape.


We are a leading company in the field of surface treatment in SE Europe, based in Slovenia, which cooperates with the most important local and global partners.

For our clients, in all industries, we have been providing indispensable services for many years, which ensure uninterrupted, quality, safe and clean production.


We have more than 10 years of experience in the field of incinerator maintenance and over 50 successfully realized RTO & RCO maintenance projects.

In order to achieve excellent technical and time responsiveness, we provide services with a range of 1,200 kilometers from our headquarters in Slovenia.

Cleaning the thermal wheel (diameter 5 meters) with dry ice (left), cleaned and uncleaned part of the heat exchanger honeycomb (right).

For EFFICIENT CLEANING, WITHOUT DAMAGE to ceramics and other parts of equipment (flaps, valves, electronics, pneumatics …) we use dry ice cleaning technology.

It is a completely COMPLETELY DRY cleaning process. After cleaning, it is possible to START the devices IMMEDIATELY, thus achieving up to 30% LESS TIME TO STOP the incinerators.

Automatic sandblasting of the inside of the power pipeline with a diameter of 1,100 mm (left), sandblasted surface (Sa3) inside the RTO.

In the phase of restoration works of internal and external structural parts of the RTO, we carry out a comprehensive renovation of surfaces. Sandblasting removes rust, old paint and impurities and roughens the surface to achieve excellent paint adhesion. For painting we use different application systems (manual, gun, airless, …) and paints according to customer requirements.

Replacement of the "saddle" ceramic layer (left) and replacement of ceramic blocks on the RCO incinerator in the cement plant (right).

As part of general service interventions, according to the standards and protocols of incinerator manufacturers, we perform disassembly, cleaning and, if necessary, replacement of ceramic fillers (“saddles”, ceramic blocks).

We use quick-assembly conveyor belts for fast and safe transport.

opinions of our customers

Regular maintenance and cleaning of the RTO system in the paint shop is a condition for reliable operation and optimal energy efficiency. In such projects, we always need a partner who adapts perfectly to our time and technical requirements ... Blast Tehnik has proven to be a reliable long-term partner with whom we have successfully carried out more than 30 cleanings and other service interventions at our RTO.

We will present ourselves at the International Fair BIAM & WELDING in Zagreb, Croatia. Visit us between 26-29. April 2022 (10 am - 6 pm) in hall 8A, at exhibition space 30.
Blast Tehnik IBS suction systems are suitable for suction of various media (dust, flammable dust, oil vapors, smoke ...). IBS suction systems can be installed in new as well as existing production lines.
Sandblasting in the field is a versatile and effective surface treatment technology for removing paint, rust, impurities and preparing surfaces for further anti-corrosion protection (painting, galvanizing, metallization, rubberizing, ...) or achieving the desired final structure.
Dry ice cleaning allows you to reduce production downtime and higher product quality. The process is fast, without the use of water and chemicals.
Cleaning the heaters is the best solution for maintaining your heating system. With dry snow cleaning technology, we clean your heaters completely without damage. In this way, we ensure flawlessly clean honeycombs and optimal use of thermal energy.
