Wilo-CronoLine-IL-E Centrifugal Pump for Specific Media Conveying in Heating Refrigeration and Cooling Systems with Series Structure
The Wilo CronoLine - IL - E is a numerically controlled dry rotor single-head pump with a series structure. It is suitable for conveying specific media in heating, refrigeration, and cooling systems. It has a variety of advanced functions and features, can meet the requirements of different working conditions, and Wilo provides related services to ensure its operation.
- Significant Energy Saving: The integrated electronic power adjustment device saves energy, and the use of IE4 motor technology and hydraulic components with MEI ≥ 0.4 further saves energy.
- Convenient Operation: The green button technology and display screen are easy to operate, and the operating parameters can be set and the pump can be controlled in various ways.
- Comprehensive Protection: It integrates double-head pump management and comprehensive motor protection with a tripping electronic device (PTC thermistor sensor).
- Optional Communication: An optional interface can realize bus communication through the plug-in IF module, and can also perform wireless data exchange with related equipment through the infrared interface, facilitating connection to the building automation system.
- High energy efficiency and reduced energy consumption.
- The production in European factories is sustainable and carbon-neutral.
It has flange connection and automatic power adjustment, and includes mechanical seal, lantern, coupling, and a drive device with integrated electronic speed control.
It is used for pumping heating water (in accordance with VDI 2035), cold water, and water-glycol mixtures (without abrasive substances) in heating, cold water, and cooling systems.
For example, IL - E 50/190 - 11/2 - R1. "IL - E" represents a series pump with an electronic controller. "50" is the nominal diameter DN of the pipe connection. "190" is the nominal impeller diameter. "11" is the rated power P2 of the motor (kW). "2" is the number of poles. "-R1" is the model without a pressure sensor.
- Temperature range: -20°C to +140°C. The mechanical seal is suitable for different temperature and medium conditions, and there are recommended models for water-glycol mixtures.
- Power connection: A variety of voltage and frequency ranges meet the electromagnetic compatibility standard.
- Protection level: IP55.
- Nominal diameter: DN 40 to DN 200.
