Hydrovar intelligent microprocessor control system

The Applied Water Systems Division of Xylem Water Systems Australia has released the latest improvement to the Hydrovar intelligent microprocessor control system.

Pumping applications for irrigation water supply, recreational turf, building services or domestic supply needs can achieve improved efficiencies and usually significant electric power savings by the application of the Hydrovar variable-speed pump controller.

The pump-mounted, variable-speed, microprocessor-based system controller has been designed to manage motor speed and match pump performance to a wide range of water industry applications. In independent tests, compared to full speed pumps, Hydrovar has provided energy cost savings of up to 70% by varying the pump performance to match water supply demands.

Now with a unique wall- or panel-mounting system, the Hydrovar system can use the output power of the drive to operate a cooling fan, therefore reducing the need for the system to be motor mounted and allowing it to become a stand-alone drive mounted directly to a wall or enclosure.

With the introduction of a wall-mounted fan kit, the system has increased capabilities for more application types and installations. The wall-mount kits are specifically designed to provide the cooling capacity required to ensure longevity of the system.

The modular design system is available as: a Master Drive that is fully featured for single or multiple pump applications; a Single Drive with reduced features for a single pump only application; or a Basic Drive for use on slave pumps in multipump applications, or soft start in single pump applications.

The system also has a unique simple clip-on design enabling it to be attached to the TEFC electric motor of most common pumps and the wall- or panel-mounted alternative makes it suitable for submersible pump installations.

It is easily integrated into existing building management systems as everything is included in the one package - microprocessor, controller, sensor, upgraded management software and a backlit LCD control panel.

Each system has an IP55-rated housing and a number of failsafe features including low-pressure shutdown.The clip-on feature allows for simple retrofitting to existing pumping systems.
