FOURGROUP E-DRIVE Booster System – 2 Pumps – Model R-C37 (2x 4Hp)

The FOURGROUP E-DRIVE Booster System – Model R-C37 with 2 pumps is designed for high-demand applications requiring large water flow and stable pressure.

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

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

The R-C37 model is ideal for large buildings, commercial systems, and industrial installations where high performance and continuous operation 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.
