Esybox Max three pump
Description
Integrated pumping system for pressurization in commercial building service. Available in two power sizes, it consists of modular elements that allow different configurations to cover the needs of medium/large condominiums and high buildings (even over 14 floors).
Each unit consists of a single connection base with up to three pump sets or one double-connection base with four pumps; various kits can be added on site if more complex requirements are needed such as those related to large structures like skyscrapers taller than 18 stories tall. This kind is often used by developers who provide their own equipment instead owning expensive units themselves – this way they don’t have any hidden costs at all! The silence and compactness dimensions make these models appropriate when noise emission must be minimized while ensuring
CONSTRUCTION FEATURES OF THE PUMP
Electronic vertical multi-impeller pump, with display, pressure sensors on intake and delivery, non-return valve on delivery and an integrated expansion
tank. Pump body and impellers in technopolymer with steel jacket.
CONSTRUCTION FEATURES OF THE MOTOR
Water-cooled permanent magnet motor, stainless steel motor jacket. Motor shaft in AISI 303 stainless steel.
CONSTRUCTION FEATURES OF THE ELECTRONIC
The variable frequency drive keeps the pressure constant by varying the number of motor revolutions according to the request.
The expansion module (esy I/O, available as an accessory) makes it possible to interface Esybox Max with the other elements of the system (BMS).
Integrated protections: protection from dry running, amperometric and abnormal voltages, overheating, freezing, anti-blocking and anti-cycling.
