Smart-box Twin GRP : a complete pressure boosting system.

Application : Cold water boosting for residential properties.

The Smart-box Twin is a self-priming multistage pump set; with electronic inverter management, flow and pressure sensors, high-resolution LCD displays and integrated expansion tanks. Complete with dry run and frost protection, plus wireless connectivity and energy monitoring facility. The pumps are mounted on a twin docking station that provides multiple pipework connection choices and ensures a simple and flexible installation base. This unit is much smaller than any other equivalent traditional system, with anti-vibration feet to maintain quiet running.

Energy saving up to 50% compared to any traditional solution. Using a water cooled motor, the operating noise is greatly reduced, making the Smart-box the quietest booster pump available in its class.

The GRP insulated tank is designed to provide a compact water storage option, WRAS Approved. High quality tank fittings include professional standard equilibrium ball valve with float and brass tank connectors. Category 5 AB water protection as standard, AG protection available on request. Capacity options from 500 Litre to 1500 Litre. A condense tray with encapsulated 1" marine ply protects tank base and allows for easier installation.

This combination of pump and modular water storage provides a complete solution for boosting mains pressure in large domestic properties.
