EPANEL / PRESSURE MAINTENANCE
Stabilize system pressure,
Let water circulate more calmly.
Serving closed heating, air conditioning and refrigeration water systems. Integrate constant pressure water replenishment, expansion buffering and on-demand vacuum degassing functions into an equipment solution that is easy to install, control and maintain.
Two major host series · Diaphragm pressure tank matching · Independent optional water replenishment tank
Automatically replenish water according to system pressure changes
Matching diaphragm pressure tank absorbs water volume changes
Degassing host circulates and separates gases in water
01 / HOW IT WORKS
Replenish water to maintain pressure, and the air pressure tank buffers expansion.
The degassing function is configured according to system requirements.
Pressure sensors monitor system pressure. When the pressure is lower than the set value, the control system starts the water replenishment pump; when it reaches the set value, it stops replenishing water to keep the system pressure within the set range.
Applicable to both seriesAs the water temperature changes, the system water volume changes. Diaphragm air pressure tanks use the compressibility of gas to accommodate expansion water and buffer pressure fluctuations. The tank volume and pre-charge pressure are determined according to the project.
Matching diaphragm pressure tankThe degassing host causes part of the system water to enter the vacuum degassing unit, causing dissolved gases to precipitate and be discharged under a negative pressure environment. The treated water returns to the system and is circulated for degassing.

02 / PRODUCT SERIES
Select host functions according to system requirements,
Then match the air pressure tank, water tank and control configuration.
YP-DB-GM
The constant pressure water replenishment host is equipped with a diaphragm air pressure tank to meet the water replenishment and expansion buffering needs of the closed water system.
YP-DBTQ-GM
In the solution of constant pressure water replenishment and diaphragm air pressure tank, a vacuum degassing unit is added to take into account water replenishment, pressure management and cyclic degassing.
| Selection items | YP-DB-GM | YP-DBTQ-GM |
|---|---|---|
| Water replenishment flow | 0.5–10 m³/h | 0.5–12 m³/h |
| Replenishing head | 40–80 m | 40–90 m |
| Degassing capacity | Not configured with degassing function | 2–30 m³/h |
| Matching pressure tank | Diaphragm pressure tank, volume and pre-charge pressure are determined according to system calculations | |
| water tank | Independently optional, not included in the host model | |
| Building communications | RS485 / Modbus optional according to project | |
The above is the commonly recommended range in the selection manual, and is not an arbitrary combination of all parameters or a fixed supply commitment. The actual flow rate, head, degassing capacity, pressure tank volume and control function are subject to project selection and confirmation of technical documents.
03 / EQUIPMENT & CONTROL
From computer room layout to daily operation,
Make the device interface and management requirements clearly connected.
CONTROL & MONITORING
Organize controls around system pressure, makeup pump operation, and degassing cycles. During debugging, confirm the pressure settings, action logic and operating parameters based on on-site working conditions, and pay attention to the pressure and equipment status during operation.
Degassing cycle control is suitable for degassing type hosts. The specific display content, alarm items, interlocking logic and RS485/Modbus interface are confirmed according to the project configuration.
04 / APPLICATIONS
Selection based on system conditions,
Connect HVAC design and equipment operation management.
For heating closed water systems, a constant pressure water replenishment and expansion buffer solution is configured based on the building height, system water capacity and temperature changes.
Heating machine room/heat exchange systemFor air-conditioning closed water systems in commercial buildings, hotels and public buildings, equipment functions are matched according to water supply and return conditions and pressure requirements.
Commercial complex/hotel/public buildingFor closed cooling water systems that require constant pressure water replenishment, the applicability and degassing configuration should be confirmed based on medium, temperature and water quality conditions.
