What is the difference between tubular radiators and stamped plate radiator?
A stamped plate radiator is made by a raw material sheet pressed in order to form the desired channels shape and welded in order to make the oil circulation take place inside these channels. Convett tubular radiator is made by elliptical tube, in a row of 9 per elements, then each element is welded together by a collector in order to distribute the oil. At first sight tubular radiator is smaller, due to its better heat dissipation (30-35% difference) and consequently lighter because it needs less elements to dissipate the same heat value then a stamped plate one.
Why I have to place embossing or spot welding?
Embossing make the fin walls more strenght, in big tanks particularly, when the oil pressure is important and when the fins dept is high. Our production lines permits to place 3 row of embossments depending on the fins depth. Another help to the fin walls strenght could be the spot welding, placed on the embossment row, this welding grant more resistance to the oil pressure and a less quantity of oil inside the tank but the same tank will be more rigid.
Why I have to apply bending on the corrugated walls?
Bendings applied to the corrugated walls, at its edges, are useful because permit to join perfectly on side of the tank to another and facilitate the welding of the whole tank. Manufacturing lines in Convett can produce more sides together of a single tank: besides the single side fin wall, we can manufacture also short and long sides together or a 3 sides fin wall until a complete 4 sides finwalls. These multiple sides may be bended in order to form a tank and avoid to lose time for the welding operations in welding workshop.
How can I fix a small painting issue on a radiator?
The painting film of a radiator (or of a tank as well) may be ruined or damaged during transport or during mounting operations. The first thing to do is to clean the surface interested on the intervention with an abrasive paper or with a metallic brush, then remove the dust with an air jet or with an humid sponge. A first layer of primer painting is needed in order to grant the adhesion to the metal surface, then as soon as it has dried out it is needed to apply the following hand, that it could be the final RAL or an intermediate hand, depending on the required environmental protection cycle.
