Lowara Hydrovar Variable Speed Drive

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 it's 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. In addition to these functions the Hydrovar can do things that are normally only performed by the most advanced computerised control systems such as:
►Stopping the pump/pumps at zero demand
►Stopping the pump/pumps in case of water failure
►Protection against dry running
►A standard feature of a 2nd required input value that allows change over between 2 different pressure settings via an external switch
►Sensor failure and over temperature of inverter and motor which protects the pump and motor from under/over-voltage

Advantages
►Motor or wall mountable
►More flexibility
►Cost savings
►Easy to commission
►Energy savings up to 70%
►Multi-pump capability which allows control from 1-8 pumps
►Enclosure IP 55

Standard versions listed above are motor mounted versions. Wall mounted versions are available here.
