What are the products offered by your company catering to Indian HVAC market?

Ensavior is offering the following energy efficient equipment and systems for the HVAC industry:

Pumping System

We offer a wide range of pumps (both constant speed and variable speed) for applications such as HVAC, plumping and firefighting. We also have skid mounted systems along with their controllers, thereby, offering a complete solution. We believe in taking the job from the intent of providing a comprehensive engineering solution rather than mere equipment selling.

Pressure Independent Control Valves (PICV) and Automatic Balancing Valves (ABV)

An effective and efficient HVAC system must provide correct energy output, when and where required. Water circuit balancing is essential to ensure that chilled water system delivers correct flows to all terminal units in an HVAC circuit. Proper hydronic balancing is the key to making an HVAC system perform efficiently and cost-effectively. To cater to this critical feature, we are offering PICV and Automatic Balancing Valves.

Thermal Energy Storage (TES) Systems

TES systems use optimum capacity chillers for using cheap off-peak electricity to store chilled water at night which can be used for meeting the peak cooling demands during the day. While TES shaves off the peak connected demand due to significant reduction in installed chiller capacity. TES system can help lower operational costs by enabling the shifting of energy consumption of chillers from peak hours (day) to off peak cost hours (night). It is prudent to note that chillers perform with much better efficiency and lower power consumption when operated at low ambient temperatures during night time as compared to day time. This contributes to a considerable energy and operational cost savings on an ongoing basis.

Chilled Water Thermal Storage systems are ideally suitable for provision of chilled water backup for mission critical facilities like data centers, defence installations and high tech manufacturing.

Ultra Violet Germicidal Irradiation (UVGI) Systems

UVGI system uses the ultraviolet energy to kill or inactivate microbes (viral, bacterial, fungal species) from forming on the cooling coils of the air handling unit and thus eliminating the possibility of unwanted unhealthy contaminants within the air-conditioned space. In addition, it also prevents the increase in power consumption by keeping cooling coils clean without any increase in airflow yet achieving the desired heat transfer. It acts as an independent maintenance system for cooling coils.

Electrostatic Precipitation System

Electrostatic precipitation systems are used for removal of grease and smoke from commercial kitchens and also smoke, fumes and oil/coolant mist from industrial process plants. It is a proven electrostatic precipitation technique to remove smoke, grease, mist and other particulates from the air to keep the outdoor air safe, healthy and pollution-free.

What are the growth drivers of your products?

Ensavior has its growth strategy in place where we focus on energy efficient and sustainable systems for the HVAC and related sectors. This strategy also looks at increasing the base business and penetration into tier-II cities. We are also gearing up to cater to the HVAC aftermarket services.

We have come a long way, delivering reliable products and services to our customers. In return, we have gained their trust and repeat orders. In our journey so far, we have thrived financially and continue to invest in our brand awareness.

Advancement in products according to the need of the hour:

TES Systems: The state-of-the-art radial diffuser design for TES Tanks ensures proper stratification of hot and cold zone throughout the operating cycles keeping tank volume (water requirement) to a minimum.

PICV: The FlowCon SM PICV, is the most advanced PICV on the market today, which can secure points for the building’s LEED certification as well.

• Guaranteeing the prevention of overflow in fully open and part open conditions has 100% authority at all times and is independent of pressure fluctuations. This leads to reduced system pressure drop and a consequential reduction in pump energy use. The accurate control of flow rates at all conditions result in temperature differences across the coils being closer to design, therefore, increasing chiller efficiency and reducing pump frequency.
• Increases the accuracy in water flow control with the pressure independent feature preventing flow rate fluctuations and consequentially, temperature changes with variations in pressure.
• Possible to link the FlowCon SM valve to the VFD pump and thereby, ensure optimal operation. It has an innovative feature, that it can correspond directly the actual flow rate to the BMS system without considering the exact differential pressure. It furthermore holds the option of direct verification of actual valve performance, settings and possible error codes, which can be used for easy building maintenance.

All our range of products is uniquely unconventional and offer great benefits and various applications in the industry, specially HVAC. We have been innovative enough to advance our products to cope up with the changing needs of the environment as well as industry.

What are the trends in current HVAC market? How would you envisage the growth with particular emphasis on energy efficiency and sustainability?

Trends in HVAC Market

The HVAC market in India is forecast to reach 25k crore by 2019. The HVAC market is influenced with growth drivers such as technological advancements which drive demand of the market with high growth rates, extreme weather conditions, steady urban development and rising infrastructure projects.

Pertaining to HVAC segment, energy efficiency, precision in design approach for resource conservation, inclination towards shorter lead time for delivery of products and services, automation and green manufacturing practices are the key elements in the current scenario that will continue to dominate the trend in pursuit of sustainability.

Treating sustainability as an objective along with all of above trends are encouraged and followed, such is the orientation of industry today. Choices of products and services have become peculiar. For all those practicing innovation, dynamic approach, flexibility and adaptability towards the emerging trends, the horizons for growth are wide and open.

Growth with energy efficiency and sustainability

The HVAC systems are responsible for a very high share of the consumed energy, which in effect contributes to global warming and climate change. Energy usage is on a gradual increase and thus, due to this reason, many projects are looking towards renewable energy sources like geothermal and solar energy.

Energy efficiency can play a major role in the future if the stepping stones are laid now. With growing energy demands, the best alternate fuel is - energy efficiency. Steadily increasing energy prices and the increasing supply-demand gap are going to create big challenges for the Indian economy. Energy efficient technologies will help address these challenges. We work closely with our customers to save energy through our energy efficient product range and solutions.

While incremental operating cost savings are being noticed with higher system efficiencies, options to upgrade to variable-capacity systems, and increased IAQ options are clearly becoming more broadly understood by the end users. With a good economic backdrop, this should continue to positively drive the HVAC segment.

In the long-term, the greatest potential for improving energy productivity will come from smart and sustainable cities with connected infrastructure where water, wastewater, heating, cooling, and electricity are integrated into one system.

How would you differentiate Indian HVAC markets from the global markets, while offering your services and products?

It would be inappropriate to generalize this difference. A better distinction could be made between countries which are developed, developing or underdeveloped. May be, not even that either. Different parts of the world have different set of factors influencing their market.

A developed nation may have better economic infrastructure as compared to the other two, they are not as price sensitive as a developing country. Despite higher financial potential a cold countries like USA or UK may have better environmental conditions and subsequently lesser sustainability challenges. On the other hand, Middle East, Asia and Africa despite having extreme conditions have enough sources to afford niche sustainable solutions. In a country like India, most of the customers are price driven, their reluctance and risk consciousness pose a major challenge to encounter. With global warming, the need for sustainability has become stringent in our country too. Thankfully we seem to have enough resources to fight it out.

What opportunities would you envisage for your company with the Indian Government’s focus on development of infrastructure like smart cities, urban transportation projects?

Infrastructure development initiatives (such as Metro rail network across the country, Smart Cities, etc.) from government have certainly given rise to massive business opportunities. New entrepreneurs are getting fair chance to contribute to this development and growth of their own. It also calls for local manufacturing from players around the globe resulting in more tie-ups, mergers and acquisition enhancing the overall economy. These initiatives have transpired in producing scope and introduction of modern technologies in the country.

Moreover, with government initiatives to promote the ‘Make in India’ concept has heightened manufacturing activities and infrastructure development in the country and with the growth in FDI (Foreign Direct Investment), several international players are starting operations in the Indian industry, which will further fuel the country’s HVAC market. Economic tailwinds combined with a business-friendly government at the center should accelerate the growth of the HVAC business as well

What are the main challenges facing the HVAC segment in India?

There is a need for testing labs and Centers of Excellence across India which can provide an opportunity for students and faculty to relate theoretical knowledge with practical functioning and better understand applications of equipment’s that are used in the HVAC space.

How do you see the future of HVAC Market?

The market for technology in the HVAC market is rapidly ever-changing. Developments for future technology focus on convenience and user experience. Although the evolution of these products in HVAC may be in their infancy, most organizations are predicting that user experience will define the industry for years to come. The emphasis on convenience is creating increased demand for technology that may not even exist yet.

The trends of the HVAC industry will continue to reflect the demands from the consumer and product safety. Technology will drive most, if not all, of these advancements. There is a parallel of service and product offerings from other industries which is helping to drive opportunity and innovation within the HVAC industry.

Smarter technology will be taking center stage, as everyone continues to battle for efficiency. There is more data available than ever before, allowing for better measurement via big data and analytics. We have to be on the lookout for simple-to-use, software solutions that make the job of delivering indoor comfort easier and more effective. Those who ignore new technology do so at their own peril.

For example, traditionally most devices have been connected using wires, but HVAC is also finding ways to shed the cords. The new IoT systems have expanded their multi-protocol to include new Wi-Fi control modules and integrated support for BACnet/MS-TP. The converged building and lighting control network supports both wired and wireless devices.
