The dual-pump configuration allows efficient load management, with pumps operating alternately or simultaneously depending on system demand, ensuring operational continuity and reliability.
With vertical multistage pump technology, the system delivers strong performance in a compact footprint. Combined with advanced inverter-driven control, it eliminates traditional start/stop cycles, ensuring constant pressure, energy efficiency, reduced noise, and lower mechanical stress on pumps and piping.
The C31 model is ideal for large buildings, commercial installations, and systems where high flow capacity and stable performance are required.
Advanced Inverter Technology – Constant Pressure System
Unlike traditional booster systems commonly used in Thailand, FOURGROUP booster systems are equipped with advanced inverter (variable frequency drive) technology.
Conventional systems operate with a start/stop mechanism: pumps switch on at full speed (50Hz) when pressure drops and switch off when the set pressure is reached. This results in pressure fluctuations, higher energy consumption, mechanical stress, and increased noise.
FOURGROUP booster systems work differently.
By continuously adjusting pump speed based on real-time water demand, the system maintains constant pressure without frequent start and stop cycles. This ensures smoother operation, higher efficiency, and significantly longer system lifespan.
