Wet rotor electronic circulator designed for the circulation of water in conditioning and heating systems in commercial building service. The integrated variable frequency drive ensures greater comfort and protection against water hammer action, and also saves energy by adapting the motor speed to actual requirements. The display enables easy configuration and the setting of the six operating modes:
(proportional differential pressure,
constant differential pressure,
constant curve adjustment,
constant and proportional differential pressure in relation to water temperature,
economy function).
The circulator is supplied with flanged suction and delivery ports (also in the twin version). The single version includes insulation shells. The Evoplus D versions are supplied as standard with an automatic non-return suction valve incorporated in the delivery port to avoid water recirculating through the unit when it is not running and a blank flange for servicing either of the two motors. Possibility of remote control with the DConnect service (DConnect Box supplied separately).

Integrated pumping system for water pressurization in commercial building service.
Available in two power sizes, the system is composed of modular elements that allow different configurations: single, double, triple or quadruple unit are possible, to cover the needs of medium/large condominiums and high buildings (even over 14 floors).
Each unit consists of the hydraulic connection base and the pumping unit which includes an electronic vertical multi-impeller pump, display, Wi-Fi module, pressure sensors, non-return valve on delivery and an expansion tank, all integrated.
The innovative support base of the pumping unit and the wireless communication between the pumps make it possible to assemble the unit directly at the installation site (O.S.A. concept) even by one person.
The variable frequency drive keeps the pressure constant by varying the number of the frequency of the motor according to the request and also thanks to the water-cooled permanent magnet motor it allows greater efficiency and energy savings.
The large display allows easy configuration of the operating parameters with the possibility of viewing them from a smartphone (via the DConnect APP) or remotely via the DConnect service. The expansion module (esy I / O, available as an accessory) gives the possibility to interface Esybox max with the BMS.
