DAB's Evoplus is a range of electronic circulators for small, medium and large community systems featuring a class 'A' energy rating and already complying with the ErP Directive 2009/125/EC, which take effect until 2015.

They are designed for hot water circulation in heating systems and cold water circulation in air conditioning systems, with maximum capacity up to 70 m3/h and a maximum head up to 18 mwc. The Evoplus range includes circulators with flanged ports up to DN 100 in single and twin version.

As part of the evolution process of the Evotron family of domestic circulator are equipped with a high efficiency synchronous motor, controlled by means of an on-board inverter. Dab claims that the combination of these elements together with the new hydraulics allow for a reduction in energy consumption of at least 70% as compared to a conventional circulator, at fixed speed.

Other features include: noise reduction due to the overpressure decrease during valve closure in a heating system, a greater ease of installation due to the elimination of the by-pass in the plant and a longer life cycle of the pump due to the reduction of the average operating speed.

A display showing the operating status is supplied as standard with all the products of the range to assist choosing between the different control modes.
