Lowara - Hydrovar HVL2.030-A0010W Variable Speed Drive - Wall Mounted Version - 240V

The Lowara Hydrovar HVL2.030-A0010W Variable Speed Drive - Wall Mounted Version is a Pump Control Module item. Voltage for this item is 240V.

HYDROVAR is an intelligent controller that matches pump performance to demand.

It controls the speed of a standard IEC motor by converting the fixed voltage and frequency from the power supply line. It can be fitted easily to any new pump system or retrofitted to existing pumps using the fast and easy “clip and play” mounting clamps.

Pump systems are very often oversized for the application and therefore using much more energy than needed. With energy savings of up to 70% at partial loads alone, the typical investment payback period is less than 2 years, depending on energy costs and pump operating times. A motor running at 80% of its maximum speed uses 48% less energy and slashes carbon emissions.

The controls available include constant pressure, system curve, constant flow or via an external signal.

Real-world product applications

• Boosting water pressure to multiple outlets in a building
• Maintaining stable pressure where demand varies
• Supplying water from storage tanks to distribution pipework
• Supporting general water supply and transfer systems
• Assisting with pressure control in utility installations

Key Product Features

• stopping the pump or pumps at zero demand;
• stopping the pump or pumps in case of water failure;
• allowing protection against dry running;
• a standard feature of a 2nd required input value that enables change over between two different pressure settings via an external switch;
• sensor failure and over temperature of inverter and motor which protects the pump and motor from under or overvoltage

• automatic test starts;
• auto cyclic change of lead and lag pump units;
• a memory for any inverter fault signals;
• an operating hours run counter;
• two levels of password protection if required

Lowara (est. 1968) is an Italian pump brand, now part of Xylem, specialising in Stainless Steel centrifugal and multistage pumps, plus boosters and borehole solutions. Typical applications include pressure boosting, HVAC circulation, irrigation, clean-water transfer and light industrial duties where corrosion resistance and reliable hydraulic performance are required.
