Lowara Ecocirc XL and XLplus Flanged Circulators

Efficiency and Connectivity for Building Management

Problem: In large buildings, old, stationary pumps are the main cause of high energy costs and malfunctions. Furthermore, modern building management systems (BMS) require pumps to "communicate" their status.

Solution: Replacing old pumps with the Lowara Ecocirc XL guarantees a rapid ROI (Return on Investment) thanks to the permanent magnet motor. The intuitive user interface allows for the selection of advanced modes such as Proportional Pressure, Constant Pressure, Constant Speed, or Delta T (Differential Temperature) Control .

Difference between Ecocirc XL and XLplus

It is essential to choose the correct model based on the specifications:

• Ecocirc XL (Standard): Ideal for stand-alone systems. It features basic communication (start/stop, error signal) and analog controls (0-10V, 4-20mA).
• Ecocirc XLplus (Advanced): Essential for smart buildings. Includes integrated Modbus RTU and BACnet communication protocols, as well as WiFi connectivity for advanced configuration from a PC/smartphone.

Frequently Asked Questions about Ecocirc XL

1. How do I identify flange connections?

Flanged XL models are indicated by the abbreviation "F" or by the DN diameter. The flanging follows the PN6/PN10 standard (check whether the counterflange has 4 or 8 holes). Typical sizes are DN32, DN40, DN50, DN65, DN80, and DN100. Always check the center distance (usually different from domestic threaded pumps).

2. Can I use Ecocirc XL for domestic hot water?

Please note: The standard black models are made of cast iron and are only suitable for closed circuits (heating/air conditioning). For domestic hot water (drinking water recirculation), you must specifically purchase the Ecocirc XL "N" (stainless steel) or "B" (bronze) version to avoid rust and contamination.

3. Does the XLplus version require external modules for Modbus?

No, and that's the big advantage. While other brands require expensive additional "plug-in" modules, the Lowara Ecocirc XLplus already has Modbus RTU and BACnet MS/TP communication natively integrated on board. Simply connect the cables to the dedicated terminals.
