What are Prado radiators - types, characteristics and rules for installing Prado batteries
Design
Prado batteries are panel heating devices. They consist of two stamped blanks, which are formed under pressure from a steel sheet. The standard sheet thickness is 1.2 mm, modifications are made of 1.4 mm thick steel on request (the model name contains the letter "T"). When stamping, two horizontal channels are formed - above and below, and vertical - 3 pieces per 10 cm of length.
Panel radiators look good
Along the vertical channels, two workpieces are connected by spot welding (welding is performed from the back side and is not visible on the front panel). Then they are welded around the perimeter with a continuous seam. To increase heat transfer to the rear side of such a panel, ribs molded from a steel sheet with a thickness of 0.4-0.5 mm can be welded. The shape of the ribs resembles the letter "P".
Depending on the number of panels and the presence or absence of additional ribbed plates between them, panel radiators of the same size have different heat output, as well as depth and weight. The number of panels and additional convective fins is shown in the name of the heater. Type 10 means that there is only one panel with the heating medium, type 20 - two panels, 11 and 21 - one and two panels with one row of ribs. The maximum number of both panels and ribs is 3.
The height of Prado steel radiators is 300 mm and 500 mm, the width is from 400 mm to 3000 mm, the depth depends on the type and varies from 72 mm to 174 mm.

Hygiene rulers
Traditional radiators, including those from the Prado company, throw dust into the air. They work like convectors, drawing in cold air from below and expelling it through the upper grill. An enormous amount of dust settles on the interior surfaces, teeming with scattering ribs. Under the influence of convection currents, it gradually spreads through the rooms, settling on surfaces.
There is a separate category of premises that have special requirements for cleanliness. These are hospital wards, operating rooms, laboratories, medical and treatment rooms. Wet cleaning is carried out here regularly to get rid of dust. Nevertheless, it remains in them, but in small quantities. To prevent dust from spreading around the premises, they use hygienic radiators, including those from the Prado company.
Consumers can choose from two lines of Prado hygienic radiators - Classic and Universal with the Z index. Features of these devices:
Side and bottom supply at customer's choice.
No ribbing.
No top grill.
Reduced heat output.
Their power is really reduced - the absence of ribbing affects. The types of radiators produced are 10Z, 20Z and 30Z. Dimensions in length - from 400 to 3000 mm, in height - 300 or 500 mm. The power for models with a height of 300 mm varies from 364 to 3171 W, for models with a height of 500 mm - from 535 to 4663 W.
Range
Three lines of heating devices are produced:
Prado Classic (Prado Classic) - radiators with side walls and upper grilles for the release of heated air. Connection - lateral, thread diameter G ½.
Prado Universal (Prado Universal) have two connection options. Each battery has four side inputs, and a bottom connection. All connections are ½ ”. The bottom connection can be in the right or left version.Also, radiators of this line are supplied complete with a built-in thermostat.
Prado Classic Z and Prado Universal Z are variants without covers and additional ribs, side and top covers. They are also called sanitary, as they meet the sanitary standards for medical institutions (there are no ribs and lids, so they are easy to wash).
In the standard version, all radiators are made of steel with a thickness of 1.2 mm, in versions from 1.4 mm, the letter "T" is added to the name. For example, Prado Classic T, Prado Universal Z T.
This is the • Prado Universal model with thermostatic expansion valve
Prado Classic can be used in systems with any type of wiring, "Prado Universal" are designed for use in two-pipe systems. They are equipped with a thermostat with a high flow resistance. For installation in one-pipe systems, a special thermostat with low hydraulic resistance is required. If you plan to install a device of this type in a one-pipe system, purchase the Classic version and install a thermostat with a large flow area.
Steel panel radiators PRADO Universal Type 21 created with one row of panels in depth with one row of ribs welded to the back of the panel, with an air outlet grille and side walls. They are used in heating systems of residential, public and industrial buildings. Panel radiators have convection elements, the side surfaces are covered with protective elements, the top surface is covered with an air outlet panel. The device is connected to the heating system according to a universal scheme: through two lower connection holes located on one side of the radiator, or through four side connection holes located in the corners of the radiator. Bottom connection accessories:(1) The bottom connection is straight; (2) Nipple; (3) Thermostat valve; (4) Thermostatic element; Delivery set of Prado Universal radiators:

Buy radiators Prado PRADO and you can get professional advice on the installation of the heating system by arriving at the Tepla Laboratory, or by calling the phones indicated on the website.
Scope and technical characteristics
Panel radiators "Prado" are made of steel, and it is subject to corrosion. Therefore, they can only be installed in closed-type systems. In such systems, steel batteries perform well and serve for a long time.
When planning the replacement of heating in multi-storey buildings, it is first of all necessary to clarify with the operating organization the parameters of the system for your home. The type of heating devices that you can put in your apartment depends on its condition.
Today high-rise buildings are heated according to several schemes. If the house is connected according to an independent scheme or has its own water treatment system, then you can install radiators made of any material, including steel. If the system is dependent, and the house is connected directly, then it is necessary to clarify the parameters of the coolant and its quality.
View from above
Steel radiators Prado can be installed in systems with the following characteristics:
coolant temperature not higher than + 120oC;
working pressure: with a sheet thickness of 1.2 mm - 0.9 MPa;
sheet 1.4 mm - 1.0 MPa;
test (pressure) pressure:
with a sheet thickness of 1.2 mm - 1.25 MPa;
sheet 1.4 mm - 1.5 MPa;
burst pressure:
with a sheet thickness of 1.2 mm - 2.25 MPa;
sheet 1.4 mm - 2.5 MPa;
the hydrogen activity of the coolant Ph from 8 to 9.5, ideally from 8.3 to 9.
If at least for some reason panel radiators are not suitable, you need to install a different type - either cast iron or bimetallic.
The amount of contamination in the coolant is also very important. If mud traps and filters are installed on the riser, their number is most likely small. But if the connection to the centralized network is direct, then the use of panel radiators is not recommended. The fact is that vertical collectors for the passage of the coolant have a small cross section. The presence of a large amount of suspended particles can cause them to clog. Since this type of heating devices is a non-separable design, if the circulation is disturbed, it will be difficult to do anything.
In general, to prevent siltation when connecting to centralized networks, it is recommended to put additional filters and mud collectors on the supply in front of the radiator entrance.
Nuances of installation work
The side connections for piping are located on both sides of the unit and have a ½ ”thread. Different connection types can be used.
But with the length of the device more than 1400 millimeters, the lower saddle and side one-way connection will be ineffective. With a significant length of the radiator, it is recommended to make a diagonal connection, assuming that the supply is from the top from one side of the device, and the outlet from the opposite from the bottom.
In the case of using the bottom connection, it is also called the bottom connection, it must be borne in mind that the feed is the second entrance from the side edge, and the "return" is located at the edge. It is forbidden to interchange them, since a tube is welded to the supply inlet at the factory, transporting the heated liquid to the upper collector, after which it is distributed along all vertically located channels.
To mount Prado steel radiators, the manufacturer advises using the brackets included with the units. These fasteners have been specially designed for them.
The brackets must be inserted into the grooves on the back of the steel panel. Depending on the length of the device, they can be 2 or 3. It is possible to install the structure on the legs, and not just fix it on the wall. True, branded supports must be ordered individually.
Installation is carried out in a specific sequence:
On a flat pre-prepared wall surface, mark the places where it is planned to install the fasteners.
The brackets must be unpacked.
The attachment points are reinforced with dowels or a special solution.
An automatic air vent or a Mayevsky tap, a thermostat and plugs must be installed on the heater, and if necessary, adapters are used.
On the radiator, in the places of mounting on the brackets, open the package and place the device on the fasteners.
Connect the pipes supplying the coolant and its outlet.
All plastic wrap is removed after finishing the cleaning work in the room.
To prevent air congestion after installing Prado radiators with a bottom connection during filling of the heating system, this should be done by means of a "return" by opening the thermostats.
Features of installation and operation
The side pipes for connecting pipes are ½ ”internal thread, they are located in two on both sides. Any connection type. But with a length of more than 1400 mm, a one-way side or bottom saddle connection becomes ineffective.For extended lengths, a diagonal line is recommended (supply from one side from above, outlet from the opposite, from below). Read how to connect radiators here.
When installing a radiator with a bottom connection, you cannot confuse the flow with the return - it will not heat
In variants with a bottom connection (bottom) of the coolant, it is necessary to take into account that the supply is the second input from the side edge, the "return" is always at 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 along all vertical channels.
For the installation of Prado panel radiators, the manufacturer recommends using the brackets included in the kit: they are specially designed for these heating devices. They are inserted into special grooves on the back of the panel. There can be 2 or 3 brackets depending on the length of the battery. There is a possibility of installation on legs, not on a wall. But branded legs are ordered separately.
The installation sequence is as follows:
on a flat prepared wall, the places for installing the brackets are marked;
the brackets are unpacked;
reinforced with dowels or mortar on the wall;
a "Mayevsky" tap (required) or an automatic air vent, if any, a thermostat or plugs, if necessary, adapters are installed on the radiator;
in the places where they are hung on the brackets, the packaging of the radiators is torn, they are installed in place;
the pipelines for supplying and removing the coolant are connected;
completely plastic 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 no more than 7 mg / l;
total hardness up to 7 mg-eq / l.
Like most radiators (except for cast iron), steel ones are negatively affected by "dry" downtime without a coolant. Frequent short-term drains are especially bad, for example, during system repairs. The total duration of the presence of heating devices without water should not exceed 15 days per year.
Steel radiators are compatible with all types of pipes, only with copper they must be connected through brass or bronze fittings and adapters.
These heaters are good with a shallow depth
Installation and connection equipment
Panel radiators Prado have excellent technical characteristics. They can operate at elevated pressure in the line, and a wide range of models allows you to select batteries for the area of the heated premises. In addition to them, Prado produces auxiliary equipment:

Reverse flow valves.
Bottom connection nodes.
Plastic and copper pipes.
Reducing couplings.
Straight, triple and angled connectors.
Clamps, adapters and much more that is necessary for the construction of a heating system.
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 assume that heating 1 m2 of area requires 100 W of heat. Something like that 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 using the tables: look for a power close to the required power. For example, for our option, the following is suitable:
The radiator must 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. It should be remembered that for normal air circulation, it is necessary to observe certain distances to the floor and window sill. It is on them and 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 rate of 100 W per square meter is the average rate for houses with average heat loss, in the middle climatic zone. In general, the amount of required heat is influenced by the climate, the area and type of glazing of windows, the material and thickness of walls, roofs, floors, the degree of recessed doors, etc. To account for all these factors, correction factors are used.

What are Prado radiators
Prado radiators are new generation batteries. They have an excellent appearance and fit harmoniously into any interior. They can be used with a closed system in individual and centralized heating. They can withstand any temperature conditions.
Thanks to high heat transfer, reliability and low thermal inertia, Prado radiators have taken their rightful place among heating appliances
In addition to excellent characteristics, Prado radiators also have a very stylish appearance. In modern and classic interiors, such batteries will look like part of the exhibition.
To better understand what a Prado battery is, you need to understand its structure. This is not difficult to do, especially if you have a list with the peculiarities of the manufacture of this radiator before your eyes.
How panel convectors are madePrado:
Steel sheets are cut. They can be 1.2 and 1.4 mm thick. One longitudinal and several vertical lines are made on these sheets. At the same time, there are three vertical stripes per 10 cm of the Prado body.
Two steel sheets are welded on the reverse side along vertical lines. So that the seams are invisible, and the structure looks aesthetically pleasing, it is welded from the back.
Also, the sheets are welded around the perimeter. Ribs are welded to the back edges of the product, the thickness of which is 0.5 mm.
Depending on the thickness of the Prado radiator, and the number of fins installed in it, its thermal conductivity will depend.
Testimonials
“There have been seven Prado units in a four-room apartment for six years now. There is nothing to find fault with. There are 17 more in the country house and 4 in the bathhouse. No complaints. "

Anatoly, Chelyabinsk
“These are not radiators, but a complete misunderstanding. In addition to the fact that they cannot be washed with a brush or a rag, they also do not heat well. They only look slightly better than old cast iron. Their only pluses are narrow and cheap. In all other respects - sheer disappointment. For two years there is already rust, and the sharp corners are sticking out. "
Natalia, Yekaterinburg
“There have been 26 Prado batteries for over a year now. Everything is good". The only complaint about this is the paintwork. The rest is normal. "
Ruban
“Of the advantages they have is the price. The minus got out during operation: when they cool, they crack. It is very audible in the bedroom. "
Boris
“For two seasons, all 4 Prado radiators, which were installed in my apartment, have flowed. They changed it all over the house, so once every one or two weeks someone must flow. Already worn out to live like on a powder keg.The quality is disgusting. "
Stepan
“We have three years of Prado in our office. They heat well, the valves are half-screwed. I heard that in 2010 there was a defective batch, but we were apparently lucky. They are okay. "

Rules for the operation of steel radiators Prado
If water is used as a working medium, it must meet certain parameters:
oxygen content not more than 0.02 mg / kg, iron up to 0.5 mg / l, other impurities maximum 7 mg / l;
the total hardness cannot exceed 7 mEq / l.
Prado steel radiators, like most appliances (with the exception of cast iron), are negatively affected by downtime without a working environment. In addition to the lack of coolant, the often produced short-term drains, for example, to repair the system, negatively affect. According to experts, the duration of the units' stay without water should not exceed 15 days during the year.
Steel devices can be combined with different types of pipe products, only with brass pipes they are allowed to be connected by means of adapters and fittings made of bronze or brass.
