System Components & Operation

Core Components:

Pressure Water Tank: Marine-grade construction for durability
Liquid Level Meter: Visual water level indication
Pressure Gauge: Real-time system pressure monitoring
Pressure Controller: Automatic pump control (0.3-0.4 MPa range)
Safety Valve: Pressure relief at 0.42 MPa
