For water heating systems, distribution combs (collectors) are used. These devices are usually manufactured with shut-off valves. The findings vary greatly in diameter. The capacity of the combs varies around 5 microns.
Air vents are mainly installed at the top of the models. Some modifications are made with several coolant taps. The limit pressure indicator for them does not exceed 6 Pa. Protection systems are most often used class C50.
Homemade devices
Do-it-yourself distribution comb for heating is assembled using a flange valve. Before installing the air vents, the protective rings are soldered. Pressure control is carried out thanks to the clamp. Many modifications are assembled without a bracket. It is better to install the control valve behind the adapter. Heat transfer should not be very long. It is also worth noting that it is advisable to clean the shut-off valves.
Types of modifications
Channel, feed and cast distribution combs are distinguished. The first type is most suitable for boiler systems. Cabinets for them are installed in different sizes. According to experts, their conductivity starts at 10 microns. The pressure indicator at the outlet is at least 5 Pa. Protection systems are often used series C50. Some modifications are able to boast of high-quality double brackets. Feeding models are most suitable for low-power heating systems.
Conductivity on air vents does not exceed 22 microns. Some experts say that it is more expedient to select modifications with several adjusting pins. Cast distribution combs are used for underfloor heating. Security systems they use C55 series. Brackets are often galvanized and are not afraid of corrosion. Stopcocks are often installed behind adapters.
Channel devices
The distribution comb of a channel-type heating system is characterized by the presence of wire valves. To date, there are many models for three air vents. They are made, as a rule, of steel. There are also wide modifications on the market that are well suited for high power boilers.
Shut-off valves for models of this type are fixed on the protective rings. Outlets for the heat carrier are installed with a diameter of up to 3.4 cm. Many distribution combs are made with a galvanized bracket. To prevent it from twisting, a small washer is used. For underfloor heating systems such modifications are poorly suited.
Feed Modifications
The distribution feed comb for heating is equipped with control valves located under the adapters. There are models on the market with exits for and without coolants. Brackets are most often mounted under the clamping ring.
Small diameter washers are most often used to fix the adapter. Air vents are used in different sizes. Valves for them can be made of copper or brass. For floor heating systems, modifications are great. However, they are also installed on boiler systems.
Cast switchgears
Cast devices are most often found in production. Shut-off valves are used with liners. Some modifications are made with safety pins. It is also worth noting that cast modifications can withstand a lot of pressure. Another advantage can be attributed to good conductivity. Cranes are often used spherical type, and they have very little wear. However, it is important to consider that cast distribution combs in cabinets take up a lot of space. Air outlets are used with a diameter of 3.3 cm or more. Outlets for coolants are most often installed in the lower parts of the structure.
Description of the Multidis SF 2-circuit models
For boiler systems up to 4 kW, this comb is suitable for heating (distribution manifold). The price of the product is approximately 5780 rubles. If you believe the experts in the field of heating, the model has excellent valves. The stand itself is made entirely of copper. The ball valve of the modification is located at the beginning of the tube.
The outlet from the coolant is provided for 3 cm. The distribution cabinet is used in class K30. The filling valve is located at the top of the rack. The capacity of the distribution comb is at least 5 microns. Some experts say that the device is suitable for small-capacity boiler systems. However, it is important to consider that the bracket for the modification is small.
Features of the Multidis SF 3-circuit comb
This is a high-quality and popular distribution comb for heating. For a studio apartment, it is great. What is the difference between this distribution comb? First of all, it is distinguished by a high limit pressure parameter. The brackets of the modification are fully galvanized. Control valves rotate in both directions.
The control cabinet is used in class P45. The manufacturer provides for an outlet from the coolant by 2.2 cm. Some experts claim that this distribution comb is not suitable for high-power boiler systems. The coolant supply pipe is installed at 3.2 cm. There is a ball-type valve, and there is a distribution comb for heating in stores of 7118 rubles.
Description of Multidis SF 4-circuit models
What is the difference between this comb for heating (distribution manifold) from other models? First of all, it is important to note that her ball valve is fixed on the upper rack. For boiler installations of 3 kW, the modification is well suited. The protection system in this case is used in class M45. Some experts emphasize that the model is quite simple to install. The manufacturer directly provides for the removal of coolant by 2.4 cm.
The shut-off valve is located above the clamp. What are the parameters for this distribution comb? The conductivity of the modification is located at around 6 microns. In turn, the pressure on the tap reaches a maximum of 5 Pa. Replacing the distribution comb for heating does not take much time. The bracket for the modification has only one. The adjusting screws can only be turned clockwise. The locking mechanism is not provided for them. Today it is worth this comb distribution for heating (market price) of about 8455 rubles.
5-circuit Multidis SF Switchgear Features
The maximum pressure of this comb corresponds to 4 Pa. The protection system is used class C45. Some customers purchase this device for boiler installations. Heat transfer is applied at 3.2 cm. Water supply problems are very rare. It is also worth noting the high quality of galvanized brackets. Corrosion and rust are not afraid of them. Air vents are installed on the upper rack. The control valves are mounted on pads. Nowadays, this comb for heating is 9,800 rubles.
Features of the distribution circuits Multidis SF for 6 circuits
The specified distribution comb for heating is primarily notable for its high throughput. The protective ring in her is made entirely of stainless steel. Many experts use the modification for powerful boilers. The ball valve of the modification cranks very tight. The protection system is used in class P34. The manufacturer provides for the removal of coolant by 2.4 cm. Only one bracket is used in the model.
