DAB 3 ESYBOX MAX 85/120 T – electronic pressure station with three pumps, 3× 380–480 V – SPECIAL OFFER

Product detailed description

DAB 3 ESYBOX MAX 85/120 T (code 60195100T) consists of three electronic pumping units ESYBOX MAX 85/120 T mounted on a triple connection base. The station increases water pressure in medium and large residential buildings, commercial properties and high-rise buildings, according to the manufacturer, even over 14 floors. It is modular, so individual parts can be transported and assembled at the installation site. Quiet operation and compact dimensions allow installation even in living areas.

Operating principle

Each unit is a vertical multi-stage pump with its own frequency converter, display, pressure sensors on suction and discharge, a check valve on the discharge and an integrated expansion tank. The electronics adjust the motor speed according to the current demand and maintain the pressure in the system at the set value in the range of 1–12 bar (factory setting 3 bar). Once the first pump is configured, the other units in the group automatically synchronize with it. According to the manufacturer's curve, the assembly delivers a head of 75 m at a flow rate of 25.2 m³/h.

Construction

• in each unit 4 impellers made of technopolymer with steel rings against wear, body made of technopolymer with a steel casing
• water-cooled motor with permanent magnets, motor casing made of stainless steel, shaft made of AISI 303 steel
• motor protection IP X5, insulation class F
• suction and discharge connections of the assembly 2"
• certificates WRAS, ACS and NSF61

Control and protection

Parameters are set on the large display of the pump or in the DConnect app – the units have built-in Wi-Fi and Bluetooth. The DSync function automatically sets the language, time and measurement units of the country of installation when the phone is connected. The electronics protect the pumps against dry running, overload, incorrect voltage, overheating, freezing, blocking and too frequent switching. An expansion module esy I/O is used to connect to the building management system (BMS).

Installation and operation

The station is installed fixed in a vertical position. It pumps clean, chemically neutral water without solid or abrasive particles with a temperature up to 50 °C, the ambient temperature can be up to 55 °C and the inlet pressure up to 5 bar. According to IVAR, the complete assembly (version T) also includes a control panel and a mounting bracket; for three units of the three-phase version, the panel E3G10.5 T 400V is intended. The electrical connection must be carried out by a qualified person.
