Xylem presents efficient large circulators for commercial applications

Posted: Thursday 24th October 2013

Xylem Water Solutions UK is enhancing its popular range of high efficiency circulator pumps with the addition of the ecocirc XL range, ideal for light or commercial applications.

The new circulator has been designed specifically for applications such as heating systems, domestic hot water systems, cooling systems, solar systems and ground source heat pumps.

The smaller 100 Watt models come as a range of single headed pumps for heating in light commercial applications. Those models utilise a unique spherical motor design and have all the features of Xylem’s existing ecocirc series, including Xylem’s unique Anti-Block Technology, but boast the ability to meet any heating and cooling requirement. The series comes with a variety of standard connections, all with port to port length of 180mm, ensuring the interchange ability with any common standard market product.

The larger models for commercial applications utilise a canned motor design. The range is made up of models DN 32, DN40, DN 50, DN 65, DN 80 and DN 100, with a port to port length from 220mm up to 360mm. The twin head models DN 32 up to DN 80 both come with port to port length of 220mm to 360mm for heating applications. For domestic hot water applications, single head threaded and flanged connections are also available in bronze.

The ecocirc XL comes with a variety of control options as standard, including constant pressure, proportional pressure or constant curve. The ‘automatic night setback’ function ensures that the circulator will only increase its performance levels when there is a demand, enabling a reduction in energy consumption and costly utility bills. All settings can be done by an easy to use display with an intuitive interface design.

Gary Wilde, Business Development and Marketing Manager for Xylem Water Solutions UK, said: “Following on from the success of the ecocirc, we wanted to develop a circulator for commercial applications which could meet heating and cooling requirements across a broad range of applications, but still maintain the value and energy efficiency that we have come to expect with the ecocirc series.

“Our ecocirc XL offers clear energy efficient features already complying with the 2015 ErP regulations. The new circulator ecocirc XL is very easy to install, set and use. With this state-of-the art high efficiency circulator, we have reduced the complexity for the user to a new minimum.”

The ecocirc XL range comes in a total of four model ranges including 18 single head cast iron which boasts a spherical or canned motor design, 8 twin head cast iron and 10 single head for domestic hot water usage in bronze. The circulator also has a digital interface to keep the user informed of the pump performance, such as operating or fault mode, flow control and set point. Through an optional wifi-module, additional settings can be achieved through the use of a standard wifi-enabled device, like a smart phone, a tabloid, laptop or PC.

A user can access the highly efficient commercial circulator through the use of a smart phone which reduces the need for any additional hardware. A smart phone app is not required as all data and settings can be accessed through a standard browser installed on the wifi-enabled device. Historical pump data, the live situation as well as many additional settings can be easily monitored or modified.

For use in installations with Building Management Services, the range is available with either BACnet or ModBus, with the hardware installed right into the circulator. A PC board with those language capabilities as accessories is therefore not necessary, enabling a quick and easy installation, setting and use.
