Combined Air Separator: What is an Air Separator and How Does it Work?

An air separator is a device used to separate airflow into substances of different densities. A combined air separator is a type that provides a more effective air separation process by using primary and secondary air streams together. In this article, you will learn more about what a combined air separator is, how many types of separators there are, what they do, where they are used and how they work.

What is a Combined Air Separator?

A combined air separator is a device that utilizes primary and secondary air streams together to provide a more effective air separation process. This device uses the force of gravity and centrifugal force to separate materials according to their different densities. First, the material is placed in the primary air stream and then the secondary air stream is used to separate the materials according to their density. In closed installation systems, it helps to remove freely circulating air from the system. These devices have been developed to minimize the damage to radiators caused by free circulating air.

How Many Types of Air Separators Are There in Underfloor Heating Systems?

Air separators used in underfloor heating systems are generally divided into 5 types:

Hydraulic Air Separator: It is a separator that has a chamber where air bubbles in the heating system circuit are collected and removes the air from the system using hydraulic principles.

Mechanical Air Separator: A separator placed in the heating system that mechanically separates the air in the system. Such separators usually use hammer, diaphragm, or surface type mechanisms.
Automatic Air Separator: A separator that automatically separates the air in the heating system circuit. Such separators usually include a flotation or a sensor that enables the detection of micro-air bubbles.
Magnetic Air Separator: It is a separator that magnetically separates the air in the system by utilizing the magnetic field of the water in the heating system.
Combined Air Separator: It is a separator that combines multiple air separation functions for the heating system. Such separators can provide a combination of hydraulic, mechanical, and automatic air separation functions.

How Does the Combined Air Separator Used in Underfloor Heating Systems Work?

The Combined Air Separator used in floor heating systems is a separator that generally provides hydraulic, mechanical, and automatic air separation functions together. These separators remove the air that may occur in heating systems from the system, allowing the system to operate more efficiently.
The device is in the heating system circuit and connected to the pipelines. In this separator, the fluidity and movement of the water in the system allows air to be separated hydraulically. In addition, a mechanical separation process can also take place in the separator. Mechanical separation is realized by means of hammer or surface type mechanisms in the separator.

The Combined Air Separator can also automatically perform air separation. This is accomplished by a sensor in the separator that detects float or micro-air bubbles. The sensor is located at one of the air collection points and when it detects air, it automatically removes it from the system.
This type of separator combines multiple air separation functions for the heating system and is therefore often used in heating systems; it efficiently separates the air in the system, ensuring longer life of the heating system with lower energy consumption.

Why Use a Combined Air Separator?

It is designed to prevent air bubbles or gas accumulations that can occur in underfloor heating systems as well as in cooling systems. It is used to remove moisture, oil vapor, particles, and other contaminants from the air and to provide clean air. Air bubbles, gas accumulations and other elements can reduce system efficiency, impede heat transfer, and cause system operation problems. Therefore, air separator devices are needed to prevent air and gas accumulation and to ensure healthy operation of the system.

Where is the Combined Air Separator Used?

Combined air separators are devices that are generally used in installation systems and especially in radiators. They are used in closed installations known as heating and cooling systems. There are different types used in domestic or industrial environments. These devices are used in central and individual heating systems, cooling systems and floor heating systems. It is specially used in industrial environments, factories, laboratories, hospitals, and other similar applications.What are t

The Advantages of Combined Air Separators?

Combined Air Separators offer many advantages by combining several different methods to separate the air in heating systems.

  • Heats Efficiently

Because it effectively separates the air in heating systems, it allows the system to operate more efficiently. This means the system consumes less energy and lasts longer.

  • Easy Maintenance

Facilitates maintenance of systems. Reduced air in the system results in less wear and tear on pumps and other equipment and reduces maintenance requirements.

  • Makes Less Noise

Reduces noise caused by air bubbles in the system. This results in a quieter heating system.

  • Longer Lifespan

By removing air from the heating system, it ensures a longer life of the pump and other equipment. This means fewer system breakdowns and less maintenance.

  • Reduces Failure Rate

Reduces errors caused by air bubbles entering the system. This results in fewer system failures and less maintenance.

  • Automatic Control

It can automatically perform the air separation function. This makes the system easier to control and manage.

  • Less Energy Consumption

As they make the heating system work more efficiently, they consume less energy. This helps to reduce energy bills.
