FOURGROUP E-DRIVE Booster System – 2 Pumps – Model R-C42 (2x 5.5Hp)

The FOURGROUP E-DRIVE Booster System – Model R-C42 with 2 pumps is designed for high-demand applications requiring very high water flow and reliable pressure performance.

The dual-pump configuration ensures efficient load distribution and system reliability, allowing pumps to operate alternately or simultaneously depending on demand.

With vertical multistage pump technology, the system delivers strong performance in both pressure and flow capacity. The inverter-driven control eliminates traditional start/stop cycles, ensuring constant pressure, improved energy efficiency, reduced noise, and lower mechanical stress on pumps and piping.

The R-C42 model is ideal for large buildings, industrial systems, commercial complexes, and installations requiring high-capacity water supply and continuous operation.

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.
