Panel heat transfer plates of aluminum produced in Canada with 50-ies. and well-known domestic consumers. radiant heating panels – is two welded together forged, 1/2 PEX Crimp tool, forming a series of vertical parallel channels, which are combined with horizontal collectors. The panels are made in single and two-row version without convection fins, as well as fins and decorative coating of heat-resistant enamels. aluminum is more than cast iron or aluminum, corrosion and therefore this type of heaters are more suitable for closed radiant heating systems – in cottages, low-rise buildings, and if an individual item of the heat – in buildings of any height. aluminum heat transfer plates in the majority of an operating pressure of 6 to 10 atmospheres, hydrostatic testing – 13 atm and the maximum coolant temperature of 1100 C to 1500 C.
Along with aluminum, manufactured in Europe bimetallic panel heat transfer plates, which are aluminum tubes that are filled in monolithic panels made of aluminum with fins or without him. Bimetal heat transfer plates free from the shortcomings inherent in an aluminum heat transfer plate (susceptibility to electrochemical corrosion, the possibility of hydrogen generation due to chemical reactions, which enters aluminum), but have the same thermal efficiency. They are used in all radiant heating systems, including those with high blood pressure. Pressure bimetallic heat transfer plates – 25 atm hydrostatic testing – 37 atm, the maximum coolant temperature – 1100 S.
