Ready for the future Energy Saving Requirements – SimFlex Glandless Circulators with Energy Label A From January 2013 the EU has legislated that all wet running circulators installed in central heating systems must be Energy Class A. Smedegaard SimFlex A models are all in accordance with these new requirements. The pump range covers many dimensions, pipe sizes and capacities for use in both existing and new applications. Fast and precise automatic capacity adjustments in response to changing operational conditions give increased energy savings. No extra modules are needed- all signal inputs are available inside the terminal box, such as input for 0-10 volt signal, start-stop signal, alarm. Slow-revolving permanent magnet motors ensure long life and quiet operation
