Circulator pump ERP
€109.22
Low energy consumption electronic pump for circulating hot water in all types of heating and solar energy systems.
Thanks to the advanced technology employed, the permanent IM-E synchronous motor and the frequency converter, the new range of IM-E circulators guarantees high efficiency in all applications, with significant benefits in terms of energy savings.
The pump has a built-in electronic device that detects the changes required by the system and automatically adapts the pump's performance accordingly, always ensuring optimal efficiency and minimal energy consumption.
The IM-E series is also suitable to replace old three-speed circulators, as far as size is concerned, as it has the same dimensions as the old series.
