Overview of model ranges of Prado panel radiators

The lineup

Design features of different types of radiators

The company's catalog includes Classic and Universal models. Products are issued with lateral and bottom eyeliner. The manufacturer offers a wide range of standard sizes, allowing you to design an optimal heating system. Structurally, the devices consist of one, two or three panels, plus fins. The company catalog contains several types of radiators. They differ in depth, the number of panels, the presence of fins.

Varieties of Prado batteries:

• Type 10 is the narrowest model (72 mm), consisting of one row of panels. Its plus is its affordable price. The disadvantages include a small heating capacity.
• Type 11 - fins are welded to the rear of the single row panel. The product is equipped with an air outlet grille and side slats.

• Type 20 is a radiator with two panels but no convection fins. There is a grid on top. Depth 82 mm.

• Type 21 - the model consists of two panels and fins between them. The heater received all the necessary trim - grille and side inserts.
• Type 22 - stamped parts are arranged in two rows, a ribbed convector is welded to each. The depth of the product is 108 mm, a grate is installed on top, and there are slats on the sides.
• Type 30 is a three-row radiator without fins. The model with the letter "Z" is offered without grille and sidewalls. V version with vertical connection.
• Type 33 - three rows of ribbed panels form a depth of 172 mm. The radiator is fully equipped with finishing elements.

Prado Classic

Prado Classic radiators are used in two-pipe and one-pipe communication networks. They can be installed in gravity systems and functioning with pumping stations. On four sides of the product there are holes for lateral piping. Radiators Classic are presented in all types. Their feature is the absence of right and left execution. The heater can be connected only on one side, a plug is placed on the second.

For institutions with increased requirements for cleanliness, Z-hygienic heaters are designed. They are devoid of ribs, side walls and gratings. When marking products, their type and dimensions are indicated. For example: model Prado Classic 22-500-500 - radiator with side connection type 22, length 500 mm, width 500 mm.

Prado Universal

The advantage of Universal batteries is a universal eyeliner. The design allows for bottom connection, hiding the heating pipes. The option of switching through 4 connecting holes in the corners of the device is possible.Products are produced in various types, from single-row to three-row. Also available is the Z series of hygienic heating appliances. The devices are equipped with connecting pipes on the right and left sides, which simplifies installation. Steel Prado Universal radiators are equipped with Danfoss thermostats that control their power. The valves are designed for a two-pipe system. When installing batteries in a single-pipe network, models with a reduced resistance of the thermostat are selected.

Features of Prado batteries

Production

To get an idea about the products in question, first of all, you should familiarize yourself with the features of production, which are listed below:

• As mentioned above, Prado batteries are manufactured in factory conditions at the facilities of the Progress company. The main raw material for heating appliances is high-carbon steel at least 1.2 - 1.4 mm thick. The manufacture of radiators begins with cutting steel sheets according to the dimensions of future radiators.
• Then the workpieces are subjected to pressure treatment in a stamping machine, as a result of which they acquire the required profile.
• Two stamped blanks are welded together using modern technology to form a panel. Prado heating radiators, depending on the model, may contain one, two or even three such panels, between which fins of thinner steel are welded, which increases the heat transfer of the device.

Finished products are first painted by electro-immersion method, after which stable powder paint is applied to them. Thanks to this, the products not only look attractive, but are also reliably protected from corrosion.

Radiator grille for air convection

Advantages

The popularity of Prado radiators is associated with the following advantages:

• The low weight of the structure makes it easy to do the installation yourself. Moreover, the brackets for fastening are very convenient, the only thing before installing the battery, you should familiarize yourself with the fastening scheme.
• Efficient heat dissipation and high heating rate.
• Panel batteries look attractive, and thanks to the use of high-quality paint, they retain their white color for a long time.
• Models with several panels provide air convection, which increases the heating efficiency.
• The price is quite democratic.
• Durability subject to the rules of operation.

Radiator Prado in the interior of the room

Flaws

The cons of Prado radiators are related to the design features, so they are common to all panel radiators.

In particular, the following points can be highlighted:

• The devices are not intended for use in centralized heating systems, as they cannot withstand high pressure and water hammer, and they also need a clean coolant.
• The coolant temperature should not exceed 120 degrees Celsius.
• The operating instructions for the devices do not recommend draining the water from the system, as this can cause corrosion inside the panels.
• The inability to accurately adjust the heating temperature, even in models equipped with a thermostat.
• On some models, problems with varnish were noted.

Of course, many models of modern heating batteries are devoid of the above disadvantages, however, if we compare the price / quality ratio, then Prado radiators clearly win. The only thing you need to make sure before buying is that the characteristics of the heating system match those of the radiators.

Scheme of designs of the model range of Prado radiators

Features of installation and operation

The side pipes for connecting pipes have an internal thread with a diameter of ?, they are located two by two on both sides. Any type of connection. But with a length of more than 1400 mm, a one-sided side or bottom saddle connection becomes ineffective. With an increased length, a diagonal connection is recommended (supply on one side from above, withdrawal from the opposite side, from below). How to connect radiators read here.

When installing a radiator with a bottom connection, you cannot confuse the supply with the return - it will not heat

In options with a bottom connection (bottom) of the coolant, it must be taken into account that the supply is the second input from the side edge, the “return” is always on the edge. It is impossible to change places: a tube is welded to the supply inlet, which transports the hot coolant to the upper collector, and from there it spreads through all vertical channels.

For the installation of Prado panel radiators, the manufacturer recommends using the brackets included in the kit: they are designed specifically for these heaters. They are inserted into special grooves on the back wall of the panel. Brackets can be 2 or 3 depending on the length of the battery. It is possible to install on legs, not on the wall. But branded legs are ordered separately.

The installation sequence is as follows:

• on a flat prepared wall, the installation locations of the brackets are marked;
• brackets are unpacked;
• reinforced with dowels or mortar on the wall;
• a Mayevsky tap (mandatory) or an automatic air vent, if any, a thermostat or plugs, if necessary, adapters, is installed on the radiator;
• in the places of hanging on the brackets, the packaging of radiators is torn, they are installed in place;
• pipelines for supply and removal of coolant are connected;
• fully polyethylene packaging is removed after finishing work.

  Recommended distances for mounting panel radiators of different depths

If radiators with a bottom connection are installed, so that air locks do not form when filling the system, it is necessary to fill it through the “return”, while opening the thermostats.

When used as a heat carrier water, it must meet the following parameters:

• oxygen not more than 0.02 mg/kg;
• iron up to 0.5 mg/l;
• other impurities not more than 7 mg/l;
• total hardness up to 7 mg-eq/l.

Like most radiators (except cast iron ones), steel ones are negatively affected by “dry” downtime without coolant. Frequent short-term drains are especially bad, for example, when repairing the system. The total duration of heating devices without water should not exceed 15 days per year.

Steel radiators are compatible with any type of pipes, only they must be connected to copper pipes through brass or bronze fittings and adapters.

These heaters are good with shallow depth

Market overview of aluminum radiators

China, as always, stands apart: batteries produced in this country are quite cheap, but their quality is very unstable.

Battery Design "Nova Florida"

As for specific brands, you can pay attention to the following:

• Nova Florida (Italy) is one of the best lines on the market. Italian radiators with internal anodizing are distinguished by high (up to 185 W) heat dissipation, good corrosion resistance, and are also able to withstand pressures up to 20 bar.The manufacturer's warranty for all operational failures ranges from 10 to 20 years, depending on the model.
• Global (Italy) is another worthy brand. The main difference of this line is the expanded dimensional grid: in addition to standard batteries with a center distance of 500 mm, you can also find two-meter heating panels that provide heat transfer of the section at the level of 450-500 W. Radiator Global with section height increased to 800 mm
• Fondital (Italy) - just like the two previous varieties, they are produced using compression molding technology. The products are characterized by a rather high, as for standard models, heat transfer - 210 W per section 0.5 m high. Other advantages include a modular design, improved seals and a relatively low weight.
• Radena (Italy). The cost of such devices is slightly higher than average, but at the same time, specialists do not have any questions about quality: the batteries hold a working pressure of up to 16 bar well, have heat transfer in the region of 170 - 195 W and resist corrosion well.
• Oasis (Russian Federation) - worthy domestic products that are produced using the extrusion method. Batteries have a good service life (from 15 years) and moderate cost.

Mounted model "Thermal"

Thermal (RF) is another domestic brand. Sectional type radiators are produced in a fairly wide dimensional grid. Products are characterized by good performance (working pressure up to 22 bar, heat transfer 160 - 170 W).

About company

The company that manufactures the radiators in question has a fairly rich history, as it was founded in the city of Izhevsk back in 1959. NITI "Progress" at that time was one of the leaders in the engineering and technical thought of the USSR.After the collapse of the Soviet Union, the company underwent reorganization and re-profiling.

It should be noted that the production of steel heating radiators at the production facilities of NITI Progress was mastered relatively recently - in 2005. At the same time, the Prado trademark was born. In parallel with this, a trading house was opened in Izhevsk, the main task of which was to promote Prado radiators in the domestic market.

To date, heating batteries manufactured under this brand have gained popularity not only in the Russian Federation, but also in other CIS countries. Moreover, the products of the Prado trading house were repeatedly awarded with cups of industry exhibitions and were awarded with diplomas.

Why is underfloor heating beneficial?

The main advantage of underfloor heating over all other types of heating is that it is hidden from view and is ideal for families with small children. In addition to the fact that babies can crawl safely for health, they will not burn themselves on heat sources that are securely hidden under the finish. In the room where underfloor heating is installed, drafts do not “walk”.

Underfloor heating reduces heating costs in homes with very high ceilings, where it is difficult to rationally organize the heating of the entire volume of the room. In the apartments, which are located on the ground floor, above damp cold basements, warm floors will provide a comfortable microclimate.

In addition, they do not dry the air, which is especially appreciated by sensitive people prone to allergies. When warm floors are an autonomous type of heating, they will help out on cold days of the off-season. Ceramic tiles, even with the best heating system, remain cold, and the use of warm floors will help out here.

Thus, the decision to install underfloor heating is for the benefit of the health of family members.

It is important to choose which system is better to apply

Appearance and dimensions of Toyota Prado diesel

The list of features of the 2009 car includes large wheel arches and many other unusual lines and shapes. The restyled version of 2013 has new optics and the radiator grill has changed, which has a different finish for individual trim levels.

In the basic version, the false radiator is black, in the rest - with a silver or metallic sheen. Changed the bumper and line of body colors. The latest versions of the Prado 150 diesel SUV are distinguished by the front end, taillights and bumper.

The body dimensions of the first diesel Prado 150 are 4760x1885x1845 mm (length, width, height). The model was assembled on the 120 series platform and increased in comparison with the previous Prada. In 2013, the length of the car grew by 2 cm, leaving 4.78 m. The latest cars have become even longer - 4.84 m.

Overview of different types of Prado brand radiators

On sale you can find models of Prado radiators with different design features. If the manufacturer indicated the designation “Type 10” in the product passport, then this indicates that you have a single-row device without convective fins. In this case, side walls will be present, but there will be no air outlet grille.

Prado radiators are also produced with the designation "Type 11" and are single-row panels with one row of fins. It is strengthened towards the back side, has side walls and an air outlet grille.If you do not need convective fins, as well as grille and side walls, then you should purchase a two-row model, which is designated as "Type 20 Z". One row of convective fins, an air outlet grille and side walls are all equipment referred to by the manufacturer as "Type 21". Prado brand panel radiators are available in 4 more varieties, they are designated as follows:

• Type 22.
• Type 30Z.
• Type 30.
• Type 33.

Aluminum heating equipment

Although many experts offer buyers to purchase Raden bimetallic heating radiators, this is not a mandatory rule. Aluminum as a manufacturing material is quite good in terms of heat output and a number of other important characteristics. If the working environment allows, the application justifies itself. Some rules still need to be taken into account.

Aluminum radiators from Radena are used in systems based on water heating. Buildings - administrative, residential, public. Suitable for low rise buildings.

Production process and cost

It's time to talk about more serious things. Let's start with a little background, which is that Raden's aluminum heating radiators are made from a number of sections. The latter are cast under high pressure. Then they are combined into a single whole. For this, steel nipples and gaskets of a special type are used.

Radiator aluminum Radena 500.

Coloring of production is made by epoxy polyester. Apply a couple of layers. If you are well versed in various technical subtleties, we add that two methods are used to create a protective coating. The first is cataphoresis. The second is electrostatic spraying.We are talking about enamel in the form of a powder. At the very end, the product is covered with a paint composition that belongs to class A.

You need to know the following - both the manufacture and painting of Radena aluminum radiators are done at an acceptable level. In total, there are two types of aluminum products to choose from - R350 and R500. The price of R350 is approximately $11.3 per section, R500 is $11.8.

Specifications

The basic properties of R350 and R500 do not differ much. We will consider the first option. If the R500 is something different, we will explain separately. Normal operation of radiators is guaranteed at a working pressure of the heat carrier of 16 atm. As for the test, it is 24 atm. The burst pressure is 50 atm.

The heat output of one section is very high - 165 watts. The R500 model has slightly more - 192 watts. In order for the heating equipment to serve for a long time, the temperature of the coolant should not exceed 110 degrees. Plus, more than 0.02 mg of oxygen is prohibited per liter of working fluid

Pay attention to pH. Valid value is from 6.5 to 9

One section of the product holds 0.275 l (R500–0.330 l). Differs in some limit and weight. R350 - 1.05 kg, R500 - 1.35 kg. Section height 431 mm and 581 mm respectively for different models. Center distance - 350 mm and 500 mm (hence the indexes in the title). The remaining indicators are again the same. For example, the depth of the radiator section is 85 mm. Width - 80 mm. The inlets intended for connection are 1 inch in diameter. White color.

We believe that the information provided is more than enough to superficially evaluate aluminum products. Let's move on to a more interesting option. We are talking about Radena bimetallic heating radiators, which are even more versatile.

Approximate cost of radiators depending on size and power

When connecting Prado heaters to the system of an apartment building, it is necessary to find out the connection scheme. With independent water treatment using steel radiators, there will be no difficulties. If the circuit is dependent, they first know the parameters of the coolant. Products are designed for the following characteristics:

• working pressure - 0.9 MPa, for models with a panel of 1.4 mm - 1 MPa;
• maximum coolant temperature - 120 ° C;
• panel weight 300 mm high - from 2.95 to 119.99 kg;
• weight of a panel with a height of 500 mm - from 8.18 to 89.84 kg;
• permissible pH values ​​​​- 8.3-9;
• connecting holes with internal thread 1/2″.

• height - 300 and 500 mm;
• length from 400 to 3000 mm;

How to choose the power of a panel radiator and its type

The power of any radiator depends on the heat loss of the room. In general, it is pleasant to consider that 100 W of heat is required to heat 1 m2 of area. This is how it can be calculated. If a radiator is needed for a room of 16 m2, then 1600 watts will be required to heat it.

Next, you need to find possible options from the tables: look for power that is close to the required power. For example, for our version is suitable:

• type 11-300-2200 - power 1682 W;
• type 20-300-1900 - 1608 W;
• type 21-300-1400 - 1616 W;
• type 22-300-1200 - 1674 W;
• type 33-300-900 - 1762 W;
• type 10-500-2000 - 1613 W;
• type 11-500-1400 - 1704 W;
• type 20-500-1300 - 1699 W;
• type 21-500-1100 - 1760 W;
• type 22-500-800 - 1734 W;
• type 33-500-600- - 1823 W.

What do these numbers mean:

• the first - type - the number of panels and finning plates;
• the second is the height of the radiator;
• the third is its length.

  The radiator should occupy at least 70-75% of the width of the window opening

From the entire list, now you need to choose the most suitable size for your conditions. At the same time, it must be remembered that for normal air circulation, certain distances to the floor and window sill must be observed. Here on them it is desirable to select. It is also desirable to take into account that the battery should cover 70-75% of the window width. Then the window will not “sweat” and condensation will not form on the wall.

But the norm of 100 W per square meter is the average norm for houses with average heat losses, in the middle climatic zone. In general, the amount of heat required is affected by climate, the area and type of window glazing, the material and thickness of walls, roofs, floors, the degree of recessed doors, etc. To take into account all these factors, correction factors are used.

Outcome

Toyota Land Cruiser Prado 120 is an emotion car, it should suit its owner. It gives a feeling of comfort and confidence. The inflated price is largely based on the model's popularity and legendary reliability. But it has been stable for many years, and by selling the Prado in a few years you will practically not lose money.

We'll have to try to find a "live" and honest copy

Pay special attention to legal verification: Title, body and frame numbers. Avoid actively off-road specimens, in harsh conditions, all components wear out 2-3 times faster

The disadvantages include mediocre interior design (by modern standards) and a rather critical age. Therefore, buy only after a test drive. Evaluate your driving experience and compare with the asking price.

Good luck on the roads!
