MATelec HydroWHIZ FPC-63420-K Mild Steel Three Phase 22 kW Variable Speed Four Pump Controller

Pressure boosting, water transfer and hot water circulation with four pumps benefit from the HydroWHIZ FPC-63420-K, offering variable-speed regulation with level, pressure and temperature operating modes. Its 22 kW VSD rating runs from a three-phase 400 Vac supply, matching motor speed to system demand.

Duty rotation balances run hours across all four pumps, with bumpless transfer ensuring smooth transitions between active drives. Additional pumps are brought into operation as demand increases to maintain the selected setpoint, then removed from service when they are no longer required. Sleep Assist Boost and Pipe Fill reduce pump cycling and gently build pipe pressure during startup, with staggered start-stop delays reducing water surge.

Proportional speed control responds to level or temperature signals, with PID control handling pressure using adjustable proportional and integral values. Housed in an IP44 mild steel cabinet with integral cooling fan and removable gland plate, the panel includes a colour touchscreen HMI. The touchscreen provides system and individual pump status, operating modes, logged events and diagnostic functions.

Modbus RTU RS485 provides SCADA connectivity, and a volt-free common fault relay delivers remote alarm signalling. Protection features include high and low limits, no-flow and feedback-signal faults. VSD and system protection functions monitor operating conditions and provide configurable responses to faults such as overload, pressure, level, temperature, no-flow and feedback-signal conditions.

Features

• Colour touchscreen HMI for monitoring, diagnostics and alarm logging
• Eight auxiliary 24Vdc digital inputs for backup float switches and pressure switches
• 4-20mA analogue input compatible with level, pressure or temperature transducers
• Thermostatic fan ventilation provides enclosure ventilation
• Jacking pump control brings Pump 1 out of sleep first, with the main pumps starting when it can no longer keep up with demand
• Configurable low-pressure and no-flow protection
• Pipe Fill gently builds pipe pressure during startup
