Group Pressure Variation Speed HM Lowara-Speedbox

The Lowara - SpeedBox range is designed to boost and transfer water pressure. Uses the latest technology to easily deliver water at the correct pressure and flow rate for residential and light commercial applications.

The SPEEDBOX series pressure groups incorporate a frequency inverter per pump intended for installations where a water supply with variable flow at a constant pressure is required.

Supply voltage 1~230V or 3~400V. Communication for groups of 2 pumps is direct with an alternating sequence of operation, in the case of 3 or more pumps, their control will be done through the SPEEDCENTER.

Variable speed operation ensures smooth pressure control and quiet performance without water hammer.
The pressure remains constant despite frequent variations in water consumption.
Compact design thanks to smart pumps.

Fiabilidade
Have multipump control or without an external control panel. HM booster sets are equipped with a pump pressure transducer via 4-20 mA signal. Operation is still possible even when one or more pumps or sensors are unavailable.

Controlo individual da bomba
Each individual pump has the ability to take control. This means that the system will continue to function as a booster system even if one or more pumps or sensors are unavailable. Compared to systems with just one control unit, the SPEEDBOX range is an extremely reliable pressure source.

Operação segura
Each frequency unit is supplied with fault diagnosis contacts and dry-running protection connections as standard. Each frequency converter in the e-HM unit has an automatic switch for thermal magnetic protection. The system incorporates the cyclical exchange of pumps, temperature sensors in the frequency units and error recordings.

Generalidades dos grupos de pressão
Control and safety system against overcurrents and dry running. ART function. When the device is turned off due to lack of water, the ART system tries to turn on the equipment at a programmed frequency until the water supply is restored. Automatic reset system due to power failure. Connection for suction tank water level float. External pressure transducer. Control and signaling panel. AIS function. It detects temperatures below 5ºC and water circulation will periodically begin to prevent freezing.
