Narayana Health Moves Towards Sustainability with Grundfos Energy – Efficient Pumping Solution
Enhancing Healthcare Infrastructure Through Smarter HVAC Upgrades
Narayana Health is a leading healthcare provider in India, recognized for offering high-quality and affordable medical services across the country. With more than 21 hospitals nationwide, the group is also committed to environmental sustainability, particularly in energy-intensive areas such as HVAC (heating, ventilation, and air conditioning) systems.
At its flagship facility, the Narayana Institute of Cardiac Sciences in Bengaluru, the hospital has 606 beds and needs reliable temperature control to maintain patient safety, comfort, and hygiene. The existing chiller plant used outdated pumps that consumed too much energy, causing inefficiencies and higher carbon emissions. The challenge extended beyond energy consumption; as a modern hospital, Narayana Health also needed to consider the integration of efficient water treatment components and related systems that support the hospital’s critical infrastructure.
Identifying the Challenge
The HVAC system at Narayana Institute of Cardiac Sciences used three old pumps that together consumed about 551,880 kilowatt-hours (kWh) every year, producing around 396 tonnes of CO₂. This led to the rise of electricity costs and went against the hospital’s sustainability goals.
Beyond HVAC, hospitals of this scale depend on integrated systems that include wastewater treatment plant components and other industrial wastewater treatment infrastructure to maintain hygiene, patient safety, and regulatory compliance. Inefficient components in these areas can exacerbate energy usage and operational costs. Narayana Health needed a modern, energy-efficient solution to improve system performance, reduce energy consumption, and meet environmental targets without disrupting critical hospital operations.
The Solution from Grundfos
Grundfos, in collaboration with its channel partner, worked closely with the hospital’s operations and maintenance teams to assess the system thoroughly. After a thorough technical survey of the chiller plant and related systems, Grundfos suggested a retrofit using high-efficiency NB series pumps, designed to save energy and work smoothly with the existing setup.
Key components of the solution included:
- NB Series Pumps: These single-stage end-suction pumps are known for their energy efficiency, reliability, and easy installation. They lower electricity use and work well with other water treatment components in the facility, ensuring smooth and efficient fluid circulation.
- CU352 Control Panel: A dedicated HVAC control system that allows precise regulation and optimization of pump performance based on real-time load demands. This system can also support monitoring and integration with wastewater treatment plant components, enabling a holistic approach to hospital infrastructure management.
This solution ensured smooth integration into the existing HVAC and water management systems, while significantly improving overall efficiency and sustainability.
Results and Benefits
Installing the NB pumps along with the CU352 control panel brought significant benefits to Narayana Health.
- 23% lower annual energy consumption
- Energy savings of over ₹1.04 million
- Reduced carbon emissions, supporting the hospital’s sustainability goals
- Better temperature control, improving the indoor environment for patients and staff
By using these high-efficiency pumps together with other industrial wastewater treatment systems and key wastewater treatment plant components, the hospital enhanced the overall reliability and performance of its operations. This retrofit demonstrates that modernizing critical infrastructure, including water treatment components and HVAC, can be done without affecting patient care, even in highly sensitive healthcare environments.
Equipment Supplied
- 4 x NB150-315
- 4 x NB150-200
- 4 x NB100-200
- 1 x CU352 HVAC Control Panel
These components modernized the HVAC system and matched standard designs used by water treatment plant manufacturers, making integration smooth and future-ready. By aligning the HVAC upgrades with wastewater treatment plant components, Narayana Health improved efficiency across several key systems.
Optimizing Sustainability in Healthcare
This project illustrates how focused investment in energy-efficient technologies and carefully selected water treatment components can make a measurable impact in the healthcare sector. Hospitals operate around the clock and consume significant energy in systems like HVAC, water circulation, and waste management. Using efficient pumps, advanced control systems, and industrial wastewater treatment solutions helps lower operational costs, enhance patient comfort, and support environmental sustainability goals.
This collaboration with Grundfos shows how important it is to work with trusted water treatment plant manufacturers and choose wastewater treatment plant components that can handle the needs of large healthcare facilities. The project also demonstrates that hospitals with older systems can upgrade efficiently with minimal disruption, setting an example for other healthcare providers.
Conclusion
The retrofit at Narayana Institute of Cardiac Sciences in Bengaluru shows how hospitals can become more sustainable without affecting patient care. By replacing outdated pumps with NB series high-efficiency models, integrating advanced control systems, and considering associated water treatment components and industrial wastewater treatment infrastructure, Narayana Health achieved both cost savings and environmental benefits.
Demonstrating that wastewater treatment plant components and HVAC systems can be upgraded together to boost energy efficiency, patient comfort, and sustainability, this project sets a benchmark for modern healthcare facilities.
Narayana Health lowered its operational costs and took a significant step toward reducing its environmental impact by using solutions from trusted water treatment plant manufacturers. As hospitals grow and the need for quality care increases, projects like this show the value of sustainable infrastructure.
This sets an example for hospitals across India and the region, as Narayana Health’s collaboration with Grundfos shows the importance of combining water treatment components, HVAC systems, and industrial wastewater treatment in modern healthcare facilities.
