Kalfrisa, S.A. products

These recuperators transfer heat (thermal energy) between primary and secondary flows by convection across smooth steel tubes. Tube type recuperators can be supplied loose, to be inserted into a horizontal flue (underground or overhead), a vertical one (chimney) flue, or, alternatively, inside lined shell.

Installations for VOC"s Volatile Organic Compounds reduction by means of thermal oxidation designed and manufactured by Kalfrisa guarantee an optimum efficiency, thanks to the appropriate selection of temperature, residence time and mixture turbulence.

VOC"s abatement installations based on the recuperative thermal oxidation technology can treat flows with a very high concentration of solvents, even over 100% of LEL or LIE (Lower Explosive Limit).

VOC"s cleaning system with a highly efficient preheating of polluted gases. It is essentially made of an oxidation chamber with two or more thermal exchangers. Accumulative masses made of ceramic material (regenerators) heat the polluted air almost up to the reaction temperature.

When VOC"s content in emissions is very low and volume of polluted air high, it is usually very profitable to make a previous concentration of polluted gases flow.

The design of the Duval crematories respects the spiritual quiet and solemnity of the environment they are installed in.

The SO series solid waste pyrolytic incinerator, thanks to its minimal installation and maintenance requirements and its ease of handling, enables high performance at low cost.
