What radiator choose? Aluminum or steel?

What radiator choose? Aluminum or steel? – Steel panel radiators are in demand due to the optimal ratio of parameters such as price, thermal power and appearance.

One of the attractive features of this type of heater is compatible with virtually all materials used for the installation of heating systems, and multiplicity of applications.

This thermal appliances, It is nice for a working pressure of 8.7 atm, the test – 13 atm and a maximum flow temperature of 110 ° C. Especially often this type of radiator used in low-rise building individually.

Not recommended to use them in systems with multiple excess operating pressure: multi-storey buildings with central heating.

Branded steel radiator brand always takes 2-3 levels of processing and surface protection. He degreased and treated in zinc phosphate bath, passes the painting cataphoresis bath, then powder coated epoxy paint (on a scale of colors RAL 9010). Ends the process of drying and processing of high-bake paint.

Double zinc phosphate coating plus guarantees  enamel surface protection against corrosion of the radiator and external influences. Increased thermal capacity of the steel radiator is achieved by spot welding to the convector coolant channels and reduced fin pitch panel.

The distances between the axes of coolant channels is not more than 25 mm. This improves heat transfer by 15-18% and reduce the cost per 1 kW of thermal power generated.

A wide selection of sizes of steel radiators allows you to choose them according to the installation conditions. Overall height is 300 to 900 mm. Overall length of 400 to 1500 mm in steps of 100 mm, and from 1600 to 3000 mm in steps of 200 mm.

Radiators, steel fasteners have a special system that allows you to install them so that the bottom connection fittings can be positioned on the left or right side.

Radiators can be connected to one or two pipe heating systems. They can be equipped with thermostatic valve. With their choice, be sure to learn a moment that they are sensitive to the content of oxygen dissolved in the coolant, so the range of applications only closed heating system. Corrosion of steel radiators increases sharply after draining the system.

Aluminum sectional radiators

This type of radiator is designed to work in systems with high pressure.

The main advantage of aluminum radiators – a material having a high thermal conductivity with low thermal inertia. Therefore, such a device responds quickly to heat loss in the room and well controlled thermostatic valve.

Aluminum radiators are made by injection molding. They operate flawlessly in such heating systems where no differences coolant acidity (pH of water is in the range of 7-8) and no surges of pressure and temperature. To exclude electrochemical corrosion at the connection points of aluminum sections with steel pipes should use special galvanized adapter.

Pleasant aesthetic feature aluminum radiators are their personal items with a convex line, producing the effect of light and shade. Therefore, these radiators look great in any design decision.
