Atmospheric Pressure Type
Typically used in open cooling water systems to ensure consistent water supply and pressure.
Pressurized Type
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.
Applications
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.
- System Pressure: 0.1-2.5Mpa

Features
- 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
