Dear Clients,

Today we would like to introduce you to the capabilities of the HYDROVAR®.

The intelligent HYDROVAR® controller adjusts pump performance to demand.
Thanks to quick and simple "clip and play" mounting clamps, installing the HYDROVAR® on existing pumps or in a new pump system is easy and fast.

A common problem in projects is oversized pumping systems that consume much more energy than necessary. By using the HYDROVAR® controller, which only partially loads the system, energy savings can reach up to 70%. For example, motor speed at 80% of maximum consumes up to 48% less energy and reduces carbon emissions.

Below are the key features of the HYDROVAR® device:

  • stopping pumps when there is zero demand, in case of water supply failure – dry run protection;
  • standard second input value function allowing switching between two different pressure settings using an external switch;
  • sensor failure and over-temperature protection of the inverter and motor, protecting the pump and motor from too low or too high voltage;
  • automatic test start-up;
  • automatic cyclic change of lead and lag units of pumps.

We hope that outlining the capabilities of the HYDROVAR® controller will clear up any doubts regarding your purchase.
