The Group’s portfolio is extensive and diverse with presence in Mouth Freshener, Food and Beverage, Confectionery, Hospitality, Agri, Luxury Retail, Tobacco businesses and also other investments.

The company is committed to create premium quality products and has built successful brands across many categories.
The DS Group Headquarters (DSHQ), situated at NCR houses the Corporate office, an R&D centre and state of art manufacturing facilities. It has been awarded Leadership in Energy and Environmental Design (LEED) Platinum certification, under the US Green Building Council (USGBC) existing building; Operation and Maintenance (O&M) programme version 4.0 for being a green building.
DSHQ is the leader amongst all LEED v4 O&M existing buildings worldwide for two consecutive years and still holds the highest number of credits amongst existing green building projects clearly making it a global leader.


The DS Group has recently performed a large retrofit project of the air handling units (AHUs) at the headquarters in Noida. The retrofit comprised replacement of 40 out-dated centrifugal fans with highly efficient, state-of-the-art NOVENCO® ZerAx® fans.
The retrofit project is part of the company's Sustainable Development journey, which aligns their business, social and environmental objectives to make significant contribution to the society at large.
The initial phase of the project included Proof of Concept (PoC) - in the form of replacing a single existing centrifugal fan with a ZerAx fan. The purpose of this pilot project was to test the ZerAx and to witness the energy savings first hand, when replacing an old centrifugal fan with a modern and advanced ZerAx axial fan.
Prior to the retrofit, the performance of one of the existing AHUs with centrifugal fan installed was measured by by our Authorised Channel Partner AIR TECHNO INDIA PVT. LTD. to establish the baseline.
The same measurements were then made post-retrofit. The results showed that for the same air flow rate the ZerAx fan had reduced the energy consumption by 55%. Once again, the ZerAx fans proved to be on the technological forefront with the highest efficiency as well as invaluable contribution to certification programmes of sustainable buildings.


As sustainability is at the core of the DS Group's mission and it’s commitment on strategic integration of sustainability into the organizational Systems and Processes. This large retrofit project not only saves a significant amount of electrical power and reduces carbon emissions, it also demonstrates the company's commitment to the green transition.
This, together with the fact that the NOVENCO ZerAx fan is 98% recyclable after a product lifetime of 20+ years, means that the AHUs installed at the DS Groups' headquarters are now truly environmental friendly. A pure and green win-win solution, for the DS Group and the environment.


"The DS Group Headquarters (DSHQ), a LEED Platinum certified green building is the leader amongst all LEED v4 O&M existing Buildings worldwide for two consecutive years and still holds the highest number of credits
amongst existing green building projects across the Globe.

We have a goal to become Zero Carbon facility by the end of 2023.

In our quest for the same, we come across ZerAx axial fans technology, which has certain benefits over the conventional centrifugal blowers such as high energy savings, lesser ROI period, improved system efficiency etc.
This product also contributes in reducing carbon emission and is certified by the The Confederation of Indian Industry (CII) as a green product.

We conducted a sample retrofit pilot project at our premises to understand the projected energy savings
and the results were encouraging.
We are delighted to share that we managed to reduce substantial energy consumption, to the tune of > 55% in our AHU systems after 1st phase of implementation.

We are satisfied with the outcome and would like to implement the 2nd phase in our other offices.", says Mr. Ramesh Kumar,
Senior General Manager, Head for Administration and Facilities, DS Group


Mr. Vikash Mishra, Deputy General Manager, Technical Facility Management, DS Group says: "We found the installation team of Air techno India Pvt Ltd highly professional and they carried the installation as per the guidelines and mutually agreed schedule.

As this was a retrofit technology, installation was done during no-operational hours for smooth execution. The system designs are extremely user friendly and the commissioning of these has the following benefits."

• Easy and customised design of the ZerAx EC+ fans has been a major positive point for proceeding with retrofitting with plug-and-play features
• These fans are compatible with our existing drives and provide better overall system efficiency
• We managed to use the existing cabling and other accessories in the system without any modification
• The ZerAx EC+ fans weigh less than the conventional fans so there is no structural/equipment additional loading over the existing system
• The compact size meant little modification of our existing AHUs. Hence no additional cost component was involved regarding changes to AHU enclosure
• Post installation activities were made smooth as the team was equipped with the necessary equipment and tools
