Integrated pumping system for water pressurisation in commercial building services.
Available in three power sizes, the system is composed of modular elements that allow different configurations: a single, double, triple or quadruple unit are possible, to cover the needs of medium/large apartments and high buildings (even over 14 floors).
Each unit consists of a 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 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.
