General Information:
There are two types of expansion tanks: open and closed.
Open Expansion Tanks
Open expansion tanks operate open to the atmosphere. It protects the system by preventing the installation from exceeding this pressure according to the pressure rate in the atmosphere.
Closed Expansion Tanks
Closed expansion tanks working with a manometer and safety valve are preferred in systems where an open expansion tank cannot be placed and operating at larger capacities.
Things to Consider in Expansion Tank Selection
- Capacity (in liters)
- To be used height of the ground
- Pressure resistance
- Auxiliary equipment to work with the expansion tank
How Are Expansion Tank (Hydrophore Tank) Prices Calculated?
Expansion tank prices are calculated in line with criteria such as capacity (in liters), height of the place to be used, pressure resistance, whether it is a horizontal expansion tank or a vertical expansion tank.
Benefits of Closed Expansion Tanks. They can be listed as follows:
- Since the heating system will return to a closed system, there is no contact with air and corrosion is reduced.
- Water does not evaporate and disappear in the closed heating system, and there is no water loss.
- In the closed system, the pressure distribution is equal and the radiators are heated evenly.
- It is mounted right next to the boiler, so it is saved from the pipe pulled up to the roof, the insulation, and the space lost by the pipes on each floor. and saves labor.
- Since the expansion tank on the roof will be removed, heat loss there is prevented.
- It is easy to install and maintain.
- It takes up little space.
**Operating Principle and Structural Details**
The basic function of expansion tanks is to control pressure fluctuations in the system by balancing the expansion and contraction of the fluid depending on temperature change. is to keep. These tanks are generally located in a closed system and consist of two main components: the internal volume and the external body. The internal volume is lined with a flexible material that allows the fluid to expand and contract. This material can usually be a membrane or an elastic substance. It ensures the stability of the system by adapting to changes in the volume of the fluid, absorbing and balancing pressure changes. The outer casing is a protective shell surrounding the expansion tank and is usually made of durable materials such as steel or plastic. This body protects the interior of the tank against external factors and increases the durability of the tank.
**Application Areas and Types**
Expansion tanks are used in many different application areas and can be found in various types. In heating systems, expansion tanks are often located next to boilers or hot water tanks. These tanks control the expansion of the heated water and ensure stability in the system by balancing the pressure of the system. Expansion tanks are also of great importance in cooling systems. Especially in large industrial cooling systems, expansion of the cooling liquid due to temperature changes is an important problem. Expansion tanks absorb the expansion of the coolant and balance pressure changes, ensuring the system operates safely and efficiently. Expansion tanks also play a vital role in hydraulic systems. Expansion of the fluid in hydraulic systems due to temperature changes can cause pressure fluctuations in the system, which can negatively affect system performance. Expansion tanks increase system performance by balancing these pressure changes and ensure that components last longer.
Expansion tanks can be found in different types according to application requirements. There are many different types of expansion tanks, including pressure vessels, membrane tanks, superficial tanks and many more. This diversity offers solutions suitable for different industrial and domestic applications and ensures that the systems are safer, more efficient and durable.
To summarize;
Expansion tanks are vital components that ensure the stability of the systems by balancing pressure fluctuations in fluid systems. They are widely used in heating, cooling, hydraulics and many industrial applications. Thanks to their structural diversity and application flexibility, expansion tanks offer solutions suitable for different requirements and ensure that systems are safer, more efficient and more durable. Therefore, expansion tanks play an important role in fluid systems and find themselves in a wide range of applications, from modern industrial facilities to domestic use.
