Your advantages
Wilo-CronoBloc-BL-E

Your advantages

  • Energy savings due to integrated electronic power adjustment
  • Optional interfaces for bus communication using plug-in IF-Modules
  • Simple operation due to tried-and-tested Green Button Technology and display
  • Integrated full motor protection (PTC thermistor sensor) with trip electronics
  • Meets user requirements thanks to performance and main dimensions in accordance with EN 733 (for end-suction pumps)

Series description

Design

Electronically controlled glanded single pump in monobloc design with flange connection and automatic power adjustment.

Application

The pumping of heating water (in accordance with VDI 2035), chilled water and water-glycol mixtures without abrasive substances in heating, chilled water and cooling systems.

Equipment/function

Operating modes

  • Δp-c for constant differential pressure
  • Δp-v for variable differential pressure
  • PID-Control
  • Constant speed (n=constant)

Manual operation level

Technical data

  • Permissible temperature range of -20 °C to +140 °C
  • Minimum efficiency index (MEI) ≥ 0.4
  • Mechanical seal for pumping water up to Tmax = +140 °C. Up to T ≤ +40 °C, a glycol admixture of 20 % to 40 % by volume is permissible. An alternative mechanical seal must be provided for water-glycol mixtures with a glycol content of > 40% to max. 50% by volume and a fluid temperature of > +40 °C to max. +120 °C or other fluids that differ from water. When using water-glycol mixtures, the use of an S1 variant with a corresponding mechanical seal is generally recommended.
  • Mains connection
    • 3~440 V -5% +10%, 50/60 Hz
    • 3~400 V ±10%, 50/60 Hz
    • 3~380 V -5% +10%, 50/60 Hz

Compliance with electromagnetic compatibility without additional measures:

    • Interference emission for residential environment according to EN 61800-3:2018
    • Interference immunity for industrial environments according to EN 61800-3:2018
  • Protection class IP55
  • Nominal diameter DN 32 to DN 150
  • Max. operating pressure 16 bar up to +120 °C, 13 bar up to +140 °C
