Stratos GIGA2.0-I 50/1-20/1,5-R1

Technical data
Tender text

High-efficiency in-line pump with EC motor of energy efficiency class IE5 in accordance with IEC 60034-30-2, hydraulics with minimum efficiency index MEI ≥ 0.7 and electronic power adjustment in glanded pump construction. The pump is configured as a single-stage low-pressure centrifugal pump with flange connection and mechanical seal. The Stratos GIGA2.0-I...-R1 has been predominantly designed for pumping heating water (acc. to VDI 2035), cold water and water-glycol mixtures without abrasive substances in heating, air-conditioning and cooling systems.

Design:

  • Single-stage low-pressure centrifugal pump with one-piece shaft in monobloc design
  • Spiral housing in in-line design (suction and pressure ports with the same flanges in a line)
  • PN 16 flange – drilled according to EN 1092-2
  • Pressure measuring connections (R 1/8) for retrofitting of a differential pressure sensor (version ...-R1 without differential pressure sensor)
  • Pump housing and motor flange with cataphoretic coating as standard
  • Mechanical seal for pumping water up to Tmax. = +140 °C. A glycol admixture of 20 % to +40 % by volume is permitted up to T ≤ +40 °C. An alternative mechanical seal must be provided in water-glycol mixtures with glycol proportions > 40 % up to maximum 50 % by volume and a fluid temperature of > +40 °C up to maximum +120 °C or fluids other than water.
  • Connection voltages: 3~440 V ±10 % 50/60 Hz; 3~400 V ±10 % 50/60 Hz; 3~380 V ±10 % 50/60 Hz

Control modes:

  • Constant speed (n-const.)
  • Constant temperature (T-const.)
  • Constant differential temperature (dT-const.)
  • User-defined PID control
  • Only possible with differential pressure sensor:
    • Permanent, automatic performance adaptation to system requirements without setpoint specification Wilo Dynamic Adapt plus (factory setting).
    • Needs-based volume flow optimisation of the feeder pump through connectivity and communication between multiple secondary pumps (Multi-Flow Adaptation).
    • Constant volume flow (Q-const.)
    • Variable differential pressure (dp-v) with the option to set the nominal duty point Q and H
    • Constant differential pressure (dp-c)
    • Differential pressure control (dp-c) to a remote point in the pipe network (index circuit evaluator)

Functions:

  • Operating modes of twin-head pump: Main/standby operation
  • Switchover between heating and cooling mode (automatic, external or manual)
  • Ability to save and restore configured pump settings (3 restoration points)
  • Fault and warning messages shown in plain text with advice on resolving the issue
  • Integrated full motor protection
  • Only possible with differential pressure sensor:
    • Heat quantity measurement
    • Cooling quantity measurement
    • Adjustable volume flow limiter using the Q-Limit function (Qmin. and Qmax.)
    • Pump automatically deactivates when no flow is detected (No-Flow Stop)
    • Efficiency-optimised parallel operation for dp-c and dp-v

Display in the "Home screen" of the graphic display:

  • Control mode currently set
  • Current setpoint
  • Current volume flow (only if a differential pressure sensor is connected)
  • Current fluid temperature (only if temperature sensor is connected)
  • Current power consumption
  • Cumulative electric consumption

Version:

  • 4 configurable analogue inputs: 0 – 10 V, 2–10 V, 0 – 20 mA, 4 – 20 mA and commercially available PT1000 (only on two analogue inputs); +24 V DC power supply
  • 2 configurable digital inputs (Ext. OFF, Ext. Min, Ext. Max, heating/cooling, manual override (uncoupled from building automation), operation lock (key lock and remote operation configuration protection))
  • 2 configurable signal relays for run signals and fault messages
  • Slot for Wilo-CIF modules with interfaces for building automation (BA) (optional accessories: CIF modules Modbus RTU, BACnet MS/TP, LON, PLR, CAN)
  • Wilo Net as a Wilo system bus for communication between Wilo products, e.g. Multi-Flow Adaptation; twin-head pump operation and Wilo-Smart Gateway
  • Automatic emergency operation with definable pump speed for exceptional circumstances, e.g. bus communication or sensor value malfunction
  • Rotatable, graphic colour display (4.3 inches) with one button manual operation level
  • Bluetooth interface via Wilo-Smart Connect module BT
  • Use the Wilo-Assistant app to read and set operating data and –among other things– set up a commissioning protocol through the Bluetooth interface
  • Integrated dual pump management (twin-head pumps are prewired) when using 2 single pumps as twin-head pump unit (connection via Wilo Net)
  • Cable break detection when using an analogue signal (in connection with 2 – 10 V or 4 – 20 mA)
  • Time stamp for error/warnings and historical operating data
  • Continuous operating data memory
  • Standard condensate drainage holes in the motor housing (closed upon delivery)
  • Air vent valve on the lantern
