Wilo-CronoTwin-DL-E

Electronically controlled glanded double pump in in-line design with flange connection and automatic power adjustment

For pumping heating water (in accordance with VDI 2035), water-glycol mixtures and cooling and cold water without abrasive substances in heating, cold water and cooling water systems
Special features/Product advantages
  • Reduced life cycle costs due to optimised of efficiency
  • Energy savings due to integrated electronic performance control
  • Control mode Δp-c for constant and Δp-v for variable differential pressure at the pump
  • Manual control mode (0–10 V/0–20 mA; 2–10 V/4–20 mA)
  • Red-button technology for simplest operation
  • Integrated full motor protection (PTC thermistor sensor) with trip electronics
  • Simple operation due to infrared interface (IR-Monitoring)
  • Optional interfaces due to retrofit IF-Modules for bus communication, LON or PLR
  • Integrated dual pump management
  • High corrosion protection due to cataphoretic coating
  • Bidirectional mechanical seal with forced flushing
  • Easy to install due to pump housing with feet and threaded holes
