DAB 2 ESYBOX MAX 85/120 T booster set with two units on 2 ESYDOCK MAX docking base – 3 × 380–480 V – SALE

Product detailed description

Booster set with two ESYBOX MAX pumps

The DAB 2 ESYBOX MAX 85/120 T set combines two ESYBOX MAX 85/120 T pump units on the double 2 ESYDOCK MAX base; according to IVAR, the complete set also includes the control panel and bracket. It is designed for boosting water pressure in residential buildings, commercial premises and high-rise buildings. According to the manufacturer, combined operation of two units gives high performance with up to 50 % less space required than traditional systems of comparable output.

Once the first pump is set up, the second one synchronises automatically; the control alternates the pumps, starts both at higher demand and one can serve as standby. For units with 3 × 380–480 V supply the manufacturer specifies the E2G7 T 400V control panel with thermal-magnetic circuit breakers, mounted on the wall or with the bracket on the units. The set is 811 mm wide, 384 mm deep and 766 mm high (1172 mm with the panel on the bracket); the connections have a 2" female thread.

Set performance

According to the manufacturer's performance table the pair of 85/120 units delivers a head of 96 m up to 12 m³/h, 75 m at 16.8 m³/h, 51.6 m at 22.8 m³/h and 9 m at 34.8 m³/h. Each unit has a maximum differential pressure of 9.4 bar, P1 max power input of 3.50 kW (4.7 HP) and rated current of 5.6 A.

Design and control

• vertical multistage centrifugal pump with four technopolymer impellers with steel anti-wear rings, non-return valve on the delivery side and 2 l expansion vessel
• permanent magnet motor cooled by the pumped water, motor casing and shaft made of stainless steel, efficiency at IE5 class level according to the manufacturer's internal tests
• frequency inverter with pressure sensors on suction and delivery keeps a constant pressure of 1–12 bar (factory setting 3 bar)
• large display, Wi-Fi and Bluetooth, DConnect app for settings, alarms and consumption overview
• protection against dry running, overheating, freezing, blocking, cycling and abnormal current or voltage
• esy I/O module (accessory) for connection to a building management system (BMS)

Operating conditions

Clean, non-viscous, non-aggressive and chemically neutral water without solid or abrasive particles up to +50 °C, ambient up to +55 °C, inlet pressure max. 5 bar, nominal pressure PN 12. The pump is not self-priming – it draws from a tank or boosts the pressure of a mains supply; when installed above the water level, the suction lift with a foot valve is max. 4 m. Fixed installation in vertical position, motor protection IPX5, insulation class F. WRAS, ACS and NSF61 certificates make it suitable for drinking water as well.

Have the electrical connection and commissioning carried out by a qualified professional; the supply must be protected by a residual current device with I Δn ≤ 30 mA.

Technical data

Frequently asked questions

What does the 2 ESYBOX MAX set contain?
Two ESYBOX MAX 85/120 T pump units and the double 2 ESYDOCK MAX docking base. According to IVAR, the complete set also includes the control panel and bracket.

What flow rate does the set achieve?
According to the manufacturer's performance table, the pair of 85/120 units delivers up to 34.8 m³/h at a head of 9 m. The full head of 96 m is held up to a flow of 12 m³/h.

How do the pumps in the set work together?
Once the first unit is set up, the second synchronises automatically. The control alternates the pumps, runs them together at higher demand and one of them can be set as standby.

What water can be pumped?
Clean, non-viscous, non-aggressive and chemically neutral water without solid or abrasive particles at up to +50 °C. Thanks to the WRAS, ACS and NSF61 certificates, ESYBOX MAX is also suitable for drinking water.
