THE LATEST SOLUTION IN SPACE SAVING POTABLE WATER PRESSURE BOOSTING

The Elvaro T is a combined tank and variable speed pump set solution designed to maximise the water storage available within a minimum available space.

Variable speed operation of the pumps means system pipework lasts longer due to the removal of the water hammer common on fixed speed operated pumps. This also provides a reduction in energy consumption and is much quieter when in operation.

The compact design of the unit not only provides a spacesaving solution, but is an ideal replacement for an existing installation. Smaller units in the range can fit through standard doorways without having to be dismantled.

Instant Pressure - ‘plug and pump’

A standard factory configuration, meaning the system is ready to provide a constant water pressure as soon as it is put into operation. Full WRAS approval of pump set in process.

Ease of Operation

The system is operated directly from the pump VSDs (Variable Speed Drives) mounted above the tank. Adjustment can be made to the control features from the VSDs if required.

Intelligent Variable Speed Control
In situations of high or low demand, the pumps automatically cycle on/off or ramp up/down which will save on energy costs and deliver optimum performance levels at all times.

Speedy Delivery

Available on most standard models within the range.
