Constant Pressure Inverter Control System

Constant Pressure Inverter Control System
TPH_IC x2 Series

Inverter controller can continuously adjust the motor speed to meet constant pressure water supply requirements.
Intelligently adjusts based on water usage conditions to achieve high efficiency and energy savings.
The system supports parallel operation, activating additional units as demand increases and alternating startup sequences at set intervals to balance usage.

Features

Inverter Controller

The motor starts smoothly during water usage, with the inverter controller continuously adjusting the motor speed via pressure sensor feedback to maintain stable pressure at the preset value.

Smart and Energy-Saving

The pump will maintain a constant operating pressure at the pressure setting, ensuring a stable water supply even though occasionally the output flow is over the capacity.

Dry-Run Protection

Auto shutoff after 1 minute of dry run; restarts hourly until water is restored.

Auto Stop Upon Flow Interruption

The pump will automatically cycle down as water usage decreases.

Pressure Compensation

Automatically detects pressure loss and operates the pump to maintain the pressure setting if there is leakage or dripping in the piping system.

Parallel Operation

When a single unit cannot meet the required pressure and flow, a second unit automatically starts to operate in parallel. It shuts down once demand decreases and one unit is sufficient.

Interchangeable Mode

When a pump has operated through the preset interval (adjustable at 0-24 hours) the system will automatically switch to the other unit. This cycle will continue through time.

Low-Noise Operation

The horizontal multistage centrifugal pump features low operational noise.
