Kalor radiators are the most classic common type of cast-iron radiators. It is very easy to use them for replacement or add-on in case of heating system reconstruction. The size, connection spacing, shape – all is the same as the years before. It works in natural and forced circulation heating systems - depending on pipe sizing and thermostatic valve use. Standard production is in ten-pieces blocks with white color water-based paint. It is possible to deliver blocks in size and color as per customer‘s request. This model is compatible with integrated thermostatic valve (ITV) with bottom water connection. Special "industrial" look can be reached using clear coating on untouched or sandblasted cast-iron surface.
