Panel radiators

Many owners of homes and property, undertaking large-scale repairs, planning, and replacement or upgrade of the heating system.And then be sure to raises the question of the new radiators.If earlier almost the only option was cast-iron battery, now available for sale represented a considerable amount of a variety of radiators, which differ not only in their appearance, but also the manufacture of the material, thermal power and other technical and operational parameters.

Panel radiators

Panel Radiators are one of the many options that have become very popular in the first place thanks to its elegant appearance.However, to stop the choice on these batteries, you must know their technical and operational characteristics, as, unfortunately, they are not suitable for all heating systems, and funds may be wasted.

This type of battery appeared in 70- th years of the last century.It was developed as an alternative to traditional cast iron radiators, which were installed throughout .

new kind of batteries in those years is not particularly caught on, because efficiency is much inferior to the usual for all cast iron variant, the more quality very first models were still quite low.Therefore, from the battery panel if it was decided to abandon.Only years later, thanks to new technological developments, their design has been improved, and new high-quality materials were used for the production.

Modern panel radiators

updated version panel batteries gained enough widespread popularity.They are produced in a wide range of sizes and are designed for different heating power.Quality panel radiators, properly selected and installed, will last a long time is true.

As manufactured panel radiators

process of making steel panel radiators in in turns the several stages:

Stamping parts for panel radiators

• Stamping panels of sheet steel thickness is typically 1.25 mm.
• convectors Making a U-shaped form required for greater heat transfer from the steel strip thickness 0,3 ÷ 0,5 mm.
• Connecting two stamped panels together.
• Securing two connected panel convectors.
• installation fittings for tie-in of the radiator system.
• painting steel panel surfaces.

panels Painting - is one of the most important stages in the manufacture of panel radiators, as the quality of the coating depends inflicted long duration operation radiators.

Everyone knows that the steel is exposed to corrosion, especially - for longer stays in a humid environment.Therefore , without high-quality color, which is conducted by a special technology, are indispensable.

staining steel panel radiators can be done in several ways:

- traditional, by dipping in a coloring composition (OP).

- According to the technology of anode electrophoresis (AEF).

- the method of cathodic electrophoresis (EFC), which is commonly used in the automotive industry.

scheme of applying a protective coating and painting radiators

EFC - the most advanced method of color steel panel radiators.He has proved a high resistance, durability and reliability cover.Technology proce ss cr Luciano in three main stages:

• The first step is to apply a very thin coating on the steel of manganese and zinc phosphate.This layers increase metal corrosion resistance, which increases the service life of the radiator.
• second stage - radiator is immersion in the ink composition and the continuation of the process of staining cathode electrophoresis.The idea is that paint container is connected to the positive electrode (cathode), while the panel itself - to a negative (anode).Staining is stopped when the composition evenly cover the entire surface of the panel - this layer acts as an insulating material.
• third stage is the process for applying an epoxy paint layer and its powder melting at high temperatures.This layer forms a high-quality glossy coating of a given color that does not fade and does not yellow, is highly resistant to external abrasions, scratched influences.

For coloring does not use substances containing formaldehyde components and heavy metals.As part of the applied paint contains only 2% of the solvent, despite the fact that the staining less advanced method AEF its content is 9 ÷ 10%.It is due to the low solvent content, radiator, even when heated to 100 ÷ 120 degrees does not emit harmful to the human body substances.

After completion of all stages of color, ready to radiators undergo test load - crimping pressure MPa 1,3 .Successful tests passage gives a guarantee on failure-free battery operation for 10 ÷ 12 years.

When at finding panel batteries, it is necessary to ask which of the three was ways to apply on meta pp cr Asuka.

In addition, you need to pay attention to the quality of the coating.It should be equally smooth and homogeneous as a radiator on the outer side, so the rear.If the quality of painting the outside and back of the radiator is visually different - it says unfair manufacture some semi-artisan way, and this option should be abandoned.

design panel radiators

Radiator may have a different design and consist of one, two or three panels, each of which is made of two steel stamped metal plates welded together along the contour.When punching in vertical plates form channels that will be by for the passage of coolant.The plates are connected to the welding seam finished panel.If several panels, they are interconnected via nozzles.In order to maximize the heat transfer between the panels (or, if it is single - somewhere behind her ) may additionally be attached plate convectors.

Template for the internal unit panel radiators

If the radiator is made up of several panels, it is often on the sides of the gaps between the bars are closed -covers .

Classification of steel panel radiators

There is a special classification panel radiators, which is expressed by a two-digit number . This is very convenient, as under the name of a particular model likewise shown immediately how many panels and convectors make general construction.

For example - take a look at the following table:

classification standard size panel radiators.

length can vary depending on the model.

radiator type	Thumbnail - appearance in different projections	Description	Mounting dimensions produced models
	Mounting height mm	Mounting length	mm Overall width in mm
10		Single row radiator with no convector and facing	305-905	405-3005	63
405-2605
11		single row radiator with convector and one facing	305-905	405-3005	63
405-2605
12		Double row radiator with convector and lining	305-905	405-3005	66
405-2605
20		DIL heatsink without convector with breathable bars	305-905	405-3005	102
405-2605
21		DIL heatsink having a convector and private housing.	305-905	405-3005	102
405-2605
22		DIL heatsink having two convector and trim.	305-905	405-3005	102
405-2605
30		The triple-radiator without convectors and facing	305-905	405-3005	157
405-2605
33		The triple-radiator with three convectors and lining	305-905	405-3005	157
405-2605

Clearly,from heatsink that is directly dependent heat transfer and functionality.For example, type 10, in the absence of convectors, only able to direct heat transfer from the surface and, to some extent, to the heat radiation.But the panels installed on heaters contribute to the creation of powerful convective upward flow of heated air, and the room warms up more quickly and efficiently.

When selecting these radiators need to consider a few points:

• upper critical temperature limit coolant provided for panel radiators, not more than 110 degrees.With stable standard temperature in the central heating system at 70 degrees, the battery will last a long time.
• Pressure should be no more than 1,0 MPa (10 bar), otherwise the design can not withstand, and leak.The central heating system operating pressure is usually 9 bar, but if you happen hammering, it is not excluded jumps to 11 ÷ 12 bar, and this is becomes dangerous for panel radiators.The pressure during the production tests - 1,3 MPa (13 bar) - is the maximum possible pressure for panel radiators.

power and size of radiators

manufacturers have provided a variety of very impressive size range for panel radiators , like in height and in width, so they can pick up under any niche in the wall, under any window, or simply on the wall - under any style of interior.Substantially flat or having a thickness certain housing may have a height of 300 to 900 mm and a length of 400 to 3000 mm.

power radiator depends on its design and on

Given the size of the installation location and the desired output, which should be chosen depending on the heated area, select the desired model of radiators and their number.

For example - table power the most popular types of radiators, depending on their size:
