Application Areas

Sectors

At Kalfrisa, we develop technological solutions tailored to meet the real-world needs of each industry.

Our applications are designed to improve efficiency, ensure safety, and promote sustainability in a wide variety of industrial environments.

Discover how our technologies deliver value, safety, and sustainability across every application area.

Food Industry

During the production of foods that use oils, fats, flavorings, or volatile additives, VOCs are released, which our thermal oxidizers remove to comply with environmental regulations.

Industrial air heaters are used for drying fruits, vegetables, herbs, grains, and cereals—reducing moisture extends shelf life without compromising product quality.

Automotive Industry

In the automotive sector, thermal oxidisers efficiently treat VOCs generated during painting and coating processes.

Industrial heaters ensure fast and even drying of vehicle coatings, enhancing surface finish quality.

Pharmaceutical

Thermal oxidisers treat and eliminate airborne pollutants generated during manufacturing, drying, coating, and cleaning processes.
Industrial air heaters supply precise and hygienic hot air where thermal accuracy and efficiency are essential.

Incineration furnaces are used to dispose of expired or rejected products, filtration sludge, defective capsules, and API residues.

RDF – Recovered Solid Fuel

The valorization of RDF (Recovered Solid Fuel) or RDF (Refuse Derived Fuel) is carried out in continuous rotary kilns, which convert the energy value of this waste into an alternative source of fuel in energy-intensive industrial processes.

They allow the use of non-recyclable waste with high calorific value, replacing fossil fuels, reducing CO₂ emissions and avoiding its disposal in landfills.

Direct Reduced Iron (DRI)

In the DRI process, iron ore is converted to metallic iron using reducing gases at high temperatures, releasing large volumes of hot exhaust gases.
Our heat recovery systems harness this energy to improve process efficiency and reduce overall energy consumption.

Flexography

This printing method uses fast-drying solvent-based inks on substrates like paper, cardboard, plastic film, labels, and bags.
Thermal oxidisers capture VOC-laden air from printing units, cleaning booths, and laminators.

Frit production

Frit production involves high-temperature melting processes that generate significant waste heat.
Our heat recovery systems repurpose this energy, reducing energy consumption and improving overall sustainability.

Aluminium melting

Aluminium melting furnaces lose substantial energy through exhaust gases.
Kalfrisa’s heat recovery units repurpose this residual energy within the process or elsewhere in the plant, improving overall efficiency and lowering emissions.

Oil & Gas

Thermal oxidisers in oil and gas are used to treat VOCs from production, refining, and storage activities.

Thermal treatment furnaces process oily sludge, drilling cuttings, and contaminated soils.

Compact heaters provide efficient and precise heating for production, processing, transport, and treatment.

Paper and pulp

In pulp and paper applications, thermal oxidisers are used to destroy VOCs generated during drying and chemical processes.
Heat recovery systems increase energy efficiency and reduce fuel consumption.

Paints & Varnishes

Our regenerative and recuperative thermal oxidisers remove VOCs released during the manufacture, drying, and application of paints and coatings.
Static furnaces for liquids safely incinerate hazardous liquid waste such as solvents and expired paints, ensuring compliance with environmental regulations.

Sulphuric Acid Production

Preheaters raise air or process gas temperature to activate the catalyst bed before introducing SO₂-rich gas.
Modular heaters maintain stable process heat during continuous operation, typically in compact, scalable configurations.

Chemical

Thermal oxidisers destroy hazardous VOCs generated during chemical manufacturing and handling.
Modular heaters deliver flexible, accurate, and efficient heating across diverse processes.
Thermal waste treatment furnaces safely incinerate hazardous waste, minimising its toxicity and volume.

Agricultural Waste

Thermal furnaces incinerate contaminated or unusable biological materials such as animal carcasses and organic by-products.

These systems eliminate pathogens and reduce volume, especially in areas lacking alternative treatment options.

Hospital Waste

Hospital waste incineration uses thermal treatment to destroy infectious, anatomical, and contaminated waste.
This process ensures complete pathogen destruction and reduces the volume and hazardous nature of the waste.

Industrial Waste

Thermal waste treatment furnaces destroy hazardous and non-hazardous industrial waste at high temperatures.
They reduce volume, neutralise toxicity, and recover heat in processes compliant with strict environmental regulations.

Steelmaking

Steelmaking is energy-intensive, with significant heat losses during melting, casting, and rolling.
Kalfrisa’s energy recovery systems improve thermal performance in these demanding environments.

Biogas Synthesis

Thermal oxidisers treat VOCs during biogas production, while heat recovery systems reclaim waste heat from combustion processes.
Heat recovery systems increase energy efficiency and reduce fuel consumption.

Textile

Thermal oxidisers destroy VOCs from solvents, inks, resins, and adhesives used in textile processes.
Compact heaters provide clean, efficient hot air for drying, fixing, environmental heating, or process conditioning.

Glass and frit production

Thermal oxidisers eliminate VOCs generated during the use of solvents, resins, or inks.
Heat recovery systems reclaim energy from high-temperature processes, reducing fuel use and enhancing plant sustainability.
