ISAN SPIRAL radiators are designed for wide use in public and residential buildings.
A characteristic feature of this radiators is the ribbed pipes through which hot water passes. The heat transfer efficiency is markedly enhanced. It is possible to connect both to hot water or steam systems. Another distinctive feature of SPIRAL radiators is its low cost.
Radiators are made of resistant materials (the main material is steel which is resistant to aggressive environment), so that they can be connected to systems with forced circulation of service water. The maximum temperature of the medium is +120 °C. The excess operating pressure should not exceed 1 MPa.
