ELECTROIL - Model ITTPD4.0 W-RS -Inverter for Circulating Pump

FromELECTROIL s.r.l.

SHARE

The inverters specific for circulating pumps are variable speed drives (VSD) of the asynchronous motor, having an algorithm specifically studied for closed ring hydraulic systems for both cold and high temperature water, combined with special high-precision pressure transducers suitable for water temperatures up to 90°C. They are available for installation directly onboard motor or for wall and can communicate each other through serial cable RS485, having functions to assistance or alternation between 2 or more circulating pumps.
