Automatic Degassing Constant Pressure Water Refill Device
Pressurisation and degassing device for central air conditioning circulating water system and boiler water system
Our automatic degassing constant pressure water refill device is designed to optimize the performance of heating and cooling systems by maintaining stable pressure and ensuring a consistent water supply. This device automatically replenish water, manage expansion, and remove both free and dissolved gases. The setup includes a control system, expansion tank, water pump, and degassing tank. Depending on your specific needs, you can choose between the atmospheric model (CY) for simpler applications or the pressurized model (DY) for more demanding environments.
Typically used in open cooling water systems to ensure consistent water supply and pressure.
Ideal for closed systems and hot water applications, such as closed boiler water systems, glycol systems, and chilled water systems, to maintain pressure and remove dissolved gases.
Ideal for centralized heating and central air conditioning systems in factories, commercial buildings, airport stations, and large urban complexes. These systems ensure efficient operation and reliable performance in demanding environments.

- Achieves exceptional pressure accuracy of up to ±0.01Mpa (±0.01bar), which is ten times more precise than traditional pressure tank methods
- Requires minimal refill pressure, allowing direct connection to tap water or other high-level water sources
- Flexible installation options, with the unit and tank separable and connected via stainless steel corrugated pipes to suit site-specific needs
- Ensures smooth and stable operation with a pressure pump that operates without vibration. Includes a backup pump, allowing for mutual backup and enhancing system reliability
- Completely isolated from the atmosphere, preventing air pockets at any point in the system and ensuring the air conditioning water system remains free from atmospheric contamination
