Distributed Pumping Systems can save energy by 40 percent

Grundfos Distributed Pumping System at Shiva Textiles reduced the pumping energy by 40 percent and improved occupant comfort.

Shiva Textiles is a leading textile retail showroom chain in southern India. Expanding to new horizons, the brand recently opened its new showroom at Salem, in the southern state of Tamil Nadu. They have been known for their wide range of ethnic wear and readymade garments and wanted to provide an unmatched and cutting-edge outlet experience for their customers. 

The Project 

Having an objective to deliver unmatched customer experience and comfort while keeping the OPEX within limits, Shiva textiles roped in Tropical Consultants, a pioneer with more than 36 years of experience in the HVAC industry, for their new retail showroom. The tropical consultant and the end user discussed with various OEMs to select the most energy-efficient chilled water pumping scheme for their project.

The Solution 

To meet the demand for the best energy-efficient chilled water pumping scheme, Grundfos proposed the concept of a Distributed Pumping System. This self-balanced chilled water circulation system uses intelligent circulator pumps with IE5 motors dedicated to each AHU, replacing the energy-consuming flow balancing and modulating valves. To make a simple yet high-performing plant with a self-balanced demand driven design packed with an intelligent pumping scheme that offers live data for further analysis and reporting.

Giridharan, Principal consultant, Tropical Consultant, Tamil Nadu, said, “The Grundfos Distributed Pumping Scheme is the most advanced, simplified and efficient chilled water distribution pumping scheme that consumes nearly 40 percent less pumping power as compared to the other pumping schemes available conventionally.” 

“When we were planning a new retail textile showroom. We wanted to invest in the latest available technology in the country.” Ravichandran Natarajan, Managing Director, Shiva Textiles, India.

The Outcome

 After observing Grundfos Distributed Pumping System’s installation, the end user and design consultant were delighted with the overall energy performance. The operation team at Shiva Textiles were thrilled to use the Grundfos GO Mobile App to monitor and report system performance on their mobile devices.

Thus, the Grundfos Distributed Pumping System reduced the pumping energy by 40 percent and addressed Delta T and improved occupant comfort compared to conventional variable primary pumping system designs. 

Ravichandran Natarajan, Managing Director of Shiva Textiles, said, “We have been using the Grundfos Distributed Pumping System for the past year. It has reduced the man hours in operation and has given us good energy savings.”
