There are a significant number of convector heaters. These also include Purmo type radiators, manufactured from steel sheet with a thickness of 1,25 mm and convection elements with a thickness 0,5 Mm. There are three types of these heaters (type C, V and P) about heights 300, 450, 600 i 900 mm and lengths from 400 into 3000 Mm, at the same time there are no difficulties in obtaining radiators of other dimensions. Construction and technical data of Purmo radiators are summarised in tables.
Selected design parameters of Purmo radiators
A series of such heaters is visible on the left side. On the right, there is a view of panel radiators with De 'Longhi convection inserts. De longhi radiators are produced in several lengths (from 400 into 3000 Mm), in five heights (300, 400, 500, 600 i 900 Mm) and with the spacing of the ribs 33,33 Mm. They appear in 10 types: as panel heaters without covers (Type P10), with side connection (Types 11K, 21K, 22K i 33K) and with lower connection (Typy 10V, 11KV, 21KV and 33KV)., Brugman products also belong to the popular panel radiators, made of steel sheet St. 12.03 with a thickness 1,25 Mm. They are adapted to be supplied with a heating medium with a maximum temperature of + 110 ° C, and the allowable pressure should not exceed 10 barium. Two types are produced (P i C), differing in the method of connection to the installation (bottom or side). One-, two- or three-disc.,
