PROJECT-CONFIGURED BOOSTER SYSTEM
YHXW Box-Type Non-Negative Pressure Water Supply Equipment
YHXW combines a hygienic buffer water chamber and a variable-frequency boosting skid in one compact box-type unit. Connected directly to the municipal network, it adds pressure on top of residual mains pressure while the buffer volume smooths peak demand.

WORKING PRINCIPLE
From inlet conditions to stable building pressure.
The controller reads the outlet pressure continuously and adjusts pump speed and staging to the actual demand.
Clean tank / inlet main→Pressure sensing→VFD pump set→Outlet sensing→Building supply
01
Water enters the hygienic buffer chamber from the municipal connection.
02
Inlet and outlet pressure are monitored as demand changes.
03
The VFD pump skid adds the required pressure and smooths peak demand.
04
The controller protects the municipal interface while supplying the building network.
