Sensorless control is an innovative concept for circulating pumps.

Pump performance and characteristic curves for 10 different speeds are pre-programmed into the memory of the IVS Sensorless speed controller. The data includes power, pressure and flow across the flow range of the pump. During operation, the power and speed of the pump are monitored, enabling the controller to establish the hydraulic performance and position in the pump’s head-flow characteristic.

Patented software technology within the controller ensures trouble-free operation under all conditions. Incorporating the pump hydraulic data into the controller and removing sensors results in true integration of all components and removes the risk of sensor failure.

SAVE COSTS OVER THE LIFETIME OF THE UNIT
In our concerns about managing initial costs, it’s easy to forget that the capital cost of a pump is typically only 5% of its lifetime cost. And lifetime cost is where the IVS really stands out. Try calculating the savings for your installation

On top of the energy savings, the speed reduction increases the life of the pump and the motor bearings, and the reduced pressure across control valves extends the life of the valves.

It all adds up. It adds up to a smarter, greener solution. It adds up to greater energy efficiency and savings in installation costs. And it adds up to savings over the life of the building. For Additional Information, Click Here
