The air & dirt separator can quickly and effectively remove free gases, microbubbles, and dissolved gases in the system, effectively solving problems such as air blockage and wheezing caused by gas in the system, affecting system safety and thermal economy.

There are a lot of air impurities in the heating and air conditioning water circulation systems, which cause great obstacles to the operation of the system. When the system is filled with water for the first time, started up and tested, and during daily installation and operation, the gas present will have a great impact on the normal operation of the system. Common problems are that the system produces air blockage, resulting in unsatisfactory local heating effect, and severe oxygen corrosion of system equipment. In addition, many existing installation components (such as floor heating systems and ceiling cooling systems) are also quite sensitive to the presence of gases in the system water. Eliminating air and impurities in the system can ensure energy-saving, efficient and smooth system operation.

Working Principle
The unique structure of the air & dirt separator is similar to the spiral degassing valve. The specially designed spiral tube is located in the center of the spiral dust collector. It can create a static area in the spiral dust collector, allowing all particles of all sizes to have time to settle to the bottom of the equipment and collect into the slag chamber. As particles are separated from the system, the pressure drop across the spiral cleaner remains constant, so blockage does not occur. When the system is operating normally, impurities can be discharged from the system through the drain valve. The equipment is equipped with a large impurity chamber that only needs to be drained regularly.
The main hazards of gases in heating and air conditioning water circulation systems are:
－Noise
－Water Circulation System Failure - Air Lock
－Oxygen Corrosion
－Reduce Pump Performance - Flow, Head
－Causes Damage to the Pump - Cavitation
－High Maintenance and Repair Costs - Frequent Replacement of Parts and Equipment
Type of Gas
1. Large Bubbles (free gas)
Large bubbles are unmeasurable in flowing liquids because of their variety in number and shape. Large bubbles are the main cause of air lock.
2. Microbubbles (<0.5mm)
Microbubbles exist on the surface of the heat exchanger, and the presence of a large number of microbubbles has a great impact on the conduction efficiency of heat exchange.
3. Dissolved Gas
Under a certain temperature and pressure, gas will dissolve in water according to the solubility coefficient. The presence of dissolved gas is the cause of oxygen corrosion.
Methods for removing air from heating and air conditioning water circulation systems:
According to Henry's law: Under a certain pressure, the solubility of gas in water is inversely proportional to temperature, that is, as the temperature increases, the solubility of gas in water decreases. At a certain temperature, the solubility of gas in water is proportional to the pressure, that is, as the pressure decreases, the solubility of gas in water decreases.
1. Utilizing the temperature difference effect and using an air & dirt separator for degassing: The core component of the air & dirt separator is the spiral mesh three-dimensional structure, which can remove free gas and microbubbles in the system. Based on the unique structure of the spiral mesh, even Tiny bubbles can also be removed, and the separated gases are collected into the gas collection chamber and eliminated through the exhaust device. It is generally installed at the high temperature point of the system. For heating systems, choose the outlet of the heat exchange equipment. For air conditioning water systems, choose the return pipe of the cooler.
2. Utilize the pressure difference effect and use a vacuum degasser for degassing: The vacuum degasser can operate efficiently in all closed water circulation systems. It removes all free and dissolved gases quickly and efficiently.
The working principle of the vacuum degasser is to place a part of the liquid in the system under a vacuum environment, and the dissolved gas in the liquid will be released and separated from the system. Afterwards, these degassed, absorptive liquids are injected back into the system to participate in the cycle. They will absorb the free gases and dissolved gases already present in the system to reach equilibrium again. This process repeats itself, and almost all the gases in the system are removed. They were all released and removed.
Slag Removal in Water Circulation Systems
The long-term and efficient operation of heating and cooling systems largely depends on whether the water in the circulation system is clean. The presence of impurities and dirt in the system can cause many problems, such as increased equipment wear and frequent system failures. Due to pipeline corrosion, pump wear, and reduced equipment efficiency in the system, maintenance costs have directly increased, causing customer dissatisfaction. If traditional filtering equipment is used to solve the problem of impurities, continuous maintenance is required. If not cleaned regularly, it will lead to an increase in pressure drop and gradually cause blockage. The air & dirt separator can remove small particles in the system, making the system completely free of impurities; It can work continuously for a long time without maintenance;
Advantages
1. During system operation, dirt can be discharged without causing unnecessary system shutdown.
2. Concentrate the removal of all dirt without maintenance, and there is no need to install backup filters.
3. No bypass valve or isolation valve is required, and the pressure drop is very small, usually 0.01 Mpa, which will not hinder the movement of the fluid.
4. Both large impurities and small particles can be removed.
Install
It is recommended to install the air & dirt separator on the main pipeline of the circulation system, preferably at the high temperature or low pressure point in the system. For heating systems, the location is at the outlet of the heating unit, and for refrigeration systems, the high temperature point is on the return water pipe of the refrigeration unit. The higher the temperature, the easier it is for microbubbles in the liquid to be released. The process of gas release is based on the principle of Henry's Law: the solubility of gas in the liquid is inversely proportional to temperature and directly proportional to pressure. When the temperature increases or pressure decreases, the dissolved gas in the liquid will be released again due to the decrease in solubility. The air & dirt separator cleverly utilizes this feature to continuously degass during the circulation process of the wave system.
Operation
1. During normal operation, it is necessary to open the inlet and outlet valves and close the drain valve.
2. When draining, open the drain valve until clean water flows out.
3. After the sewage discharge is completed, close the sewage valve.
4. If the sewage pressure is insufficient, close the valve at the water outlet.
5. Pay attention to the pipeline and water flow direction during installation.
6. The floor plan needs to flow out of the operating space of managers. Since there are no moving parts in the working process of the equipment, the equipment is maintenance-free. However, it is necessary to keep the inlet load stable and the drain valve opening and closing force to be even. Avoid human damage.
