USAGE

COIL–KO2 is the universal convector suitable for use especially in wet spaces, where intensive flooding of the trough space occurs – e.g. swimming pools. The convector body is divided into 2 sections with a longitudinal partition. The narrower (empty) section of the trough is used to collect most of the water coming into the convector from the swimming pool area thus protecting the wider section of the convector with the fan and heat exchanger from excessive flooding. Both longitudinal separated sections of the convector are fitted with drain pipes for the removal of the water from the bottom of the trough. The partition wall includes fall-over openings. The wider section of the trough with the fan and the heat exchanger is used for standard heating or partial cooling of the interior. The whole body of the unit is covered with an integral grille. The convector features high heat transfer levels when the fan is switched on but it also tempers the space when the fan is switched off. With 12V operation MINIB convectors are safe for applications in wet interiors as well. The convector cannot be installed to swimming pools with salt or other aggressive water.
