Vacuum exhaust device

1. Product Introduction
Every experienced expert understands the hazards of air problems in heating and cooling systems. Just like the research report of the University of Dresden shows that more than 90% of the circulation system is affected by air problems. As the final solution to the air problem, the vacuum exhaust device can automatically perform central exhaust in the heating and cooling water circulation system, and effectively solve the air problem in every corner.
The high-efficiency performance of the vacuum exhaust device has been scientifically certified by the University of Dresden, and countless application examples also prove that: at any time, the vacuum exhaust device can easily and reliably remove air from the circulation system.
Vacuum exhaust device can almost completely exhaust the gas in the road. Whether in a pure water system or in a lengthy pipeline system of various solutions, continuous or intermittent exhaust methods are set by different procedures. Different exhaust methods will be optimally adjusted according to the actual conditions of starting, working conditions and monitoring signals. This method eliminates the need for effort during system commissioning or maintenance and can quickly and reliably remove gas.

2. Application range
The application of vacuum exhaust devices in the following areas has achieved great success:
◆ Cooling circulation system of various production processes
◆ Various closed circulation systems such as central heating or air-conditioning systems in industrial buildings

3. Product Features
◆ During the initial operation of the system, no complicated manual exhaust is required.
◆ The system is always running at full load.
◆ Effectively prevent the pump from being cavitation.
◆ No air bubbles on the surface of the parts to be cooled, so the cooling effect is better.
◆ Almost no gas in the circulating water will bring less corrosion and loss, and less dirt accumulation.

5. Selection description
◆ The selection of vacuum exhaust device is mainly based on three parameters: the water capacity of the circulation system, the return water temperature of the circulation system, and the return water pressure of the circulation system.
◆ For example: a heating circulation system, the system water capacity is 240m³, the supply and return water temperature is 90/75 ℃, and the system constant pressure is 0.4MPa. The selection of vacuum exhaust device is YXTQ-9.
◆ If the circulation system is large, you can choose two or more units to run in parallel.
