Engineering a Greener Tomorrow
At Dunham-Bush, sustainability is not an afterthought, it’s a responsibility we take seriously. For over a century, we’ve combined engineering excellence with environmental stewardship, creating HVAC solutions that deliver comfort efficiently while protecting the planet.
Our focus is simple yet powerful: to make every degree of comfort smarter, cleaner, and more sustainable.
Our Approach to Sustainable Innovation
We continuously invest in research and development to design systems that reduce environmental impact without compromising on performance. From energy-saving technologies to eco-efficient manufacturing, every Dunham-Bush innovation is built with the future in mind.
Our advanced HVAC systems are designed to:
- Lower energy consumption and operating costs
- Reduce carbon emissions and environmental impact
- Support green building certifications and compliance
- Deliver long-term reliability through smart engineering
Our Key Green Technologies
Ice Thermal Storage Air Conditioning Systems
Smart energy storage for peak efficiency. The Ice Thermal Storage System stores cooling energy during off-peak hours and uses it when demand is highest, similar to storing energy in a battery. This reduces peak energy load, cuts operating costs, and improves overall efficiency by up to 20%, contributing to substantial carbon savings for large commercial and industrial setups.
Heat Recovery Air Conditioning Systems
Turning waste into usable energy. By capturing waste heat from the cooling process through a shell-and-tube de-superheater, this system generates hot water for sanitary or process applications. It eliminates the need for dedicated boilers, saving energy, cost, and space while reducing overall environmental impact.
Geothermal Heat Pump Systems
Harnessing the power beneath the earth. Our Geothermal Heat Pump Systems use groundwater or stable underground temperatures instead of outside air for heating and cooling. This enables 25–50% lower energy consumption and significant emission reductions, providing efficient and sustainable comfort solutions for all climates.
CO₂ / NH₃ Cascade Refrigeration Systems
Natural refrigerants for responsible cooling. This advanced cascade system combines the advantages of CO₂ and ammonia, using ammonia only in the engine room and CO₂ for the processing and storage areas. The result is higher efficiency, lower power usage, and reduced environmental risk, a breakthrough in sustainable refrigeration technology.
The Dunham-Bush India Impact
In India, where energy efficiency and sustainability are key national priorities, Dunham-Bush is playing an active role in transforming the HVAC landscape. Our locally deployed systems support:
- Green buildings and LEED-certified infrastructure
- High-performance commercial complexes and industrial facilities
- Environmentally conscious developers and consultants seeking long-term value and efficiency
Through local engineering expertise and global innovation, we deliver HVAC solutions built for India’s diverse climates and sustainability goals, helping industries lower costs, reduce emissions, and move toward a carbon-neutral future.
Our Environmental Commitment
Sustainability guides everything we do, from product design to production.
We remain committed to:
Shaping the Future of HVAC
At Dunham-Bush, we believe that innovation and sustainability are inseparable. As we continue to advance HVAC technology, we are proud to contribute to a cleaner, more efficient, and more sustainable future for India and for the world.
