NATURAL CONVECTION – REGULATION and ACCESSORIES

Regulation of the heating medium flow forms a central role in the correct control of convector heating output. Correct selection of regulation elements guarantees a comfortable ambient temperature and contributes to heating cost minimalization.

ACCESSORIES

Regulation is designed for all model lines with natural convection:
Outside temperature varies continuously during the heating period. Regulation elements are installed to the heating system to meet your desired ambient temperature and to eliminate the negative impact of outside temperature changes. Thanks to well-designed regulations the KORAFLEX, KORALINE, KORAWALL, KORASPACE and KORABASE model lines achieve optimal heating efficiency and considerable financial savings.
