2. DearAll
It's a pleasure to introduce
A.T.E.'s cleantech solutions
to you! Since the last few
years, we've been hard at
work crafting products and
processes that impact the
air, water, energy, and
information spheres. The
articles in this newsletter
are put together to offer you
green choices that are eco-
friendly and also strengthen your bottom line, as all
our offerings are specially designed to have low life cycle
costs.
How and why did we go down this path? How did we
choose the businesses we are in? This is something I'm
often asked. Let me give you some answers…
There are many factors that led to our entry into
cleantech. First, the board of A.T.E. has always been
socially driven. We think it is a good idea to achieve
societal goals through business. Second,A.T.E. has also
always been environmentally conscious. Even in the
1970s we built effluent treatment plants for our own
facilities, even when there were no regulatory needs.
Third, I have always been passionate about
sustainability and wanted to get involved in socially
useful business, particularly as I am deeply concerned
that India is vulnerable to the effects of climate change.
Fourth, we also saw a business opportunity in cleantech
that would also mesh well with our existing businesses.
We searched among many options and came up with a
lot of exciting opportunities. One was the idea of
designing and building effluent treatment plants. India
has very low water availability per capita and so this is a
business with real social utility. And everywhere in the
world we need to clean water properly before we
discharge it. Second, we realized that for machine
manufacturers with a large installed base, remote
monitoring could be a fantastic route to energy and
performance optimization. Again, as we are resource
constrained, resource saving is an important
consideration. Third, we thought that if we could offer
comfort air conditioning at an affordable lifecycle cost,
we could bring comfort to millions of people working in
factories and offices, which will also boost productivity –
but without the heavy power use of air conditioners,
which make up the fastest growing component of power
utilisation in the tropics. Fourth, we have developed in-
house static control, air cleaning, ink handling and heat
exchange products that enhance the efficiency of a
variety of processes. Finally, we've been exploring solar
thermal technologies, in which currently we are piloting
our products. These can save wood, and fossil fuels, and
hence are meaningful.
At A.T.E. our endeavor has been to provide original
technologies. We have set-up our own R&D to develop
our own products and processes. Today, we have our
own IP including several patents. For example, at the
heart of our comfort air conditioning products is our
patented dry air moist air (DAMA) heat exchanger
technology, which is now well proven with over 19 million
CFM installations covering more than 3.7 million sq. ft. all
over India. This works on 100% fresh air and provides
better conditions and indoor air quality for people
comfort, and processes. In wastewater treatment we
have a knowledge base from over 200 successful
installations in India and abroad. We have developed the
highly successfulAAA(air floatation, anaerobic, aerobic)
process that enhances biological treatment efficiency
and minimizes sludge generation, as well as AVR
(anaerobic venturi reactor) based biomethanation plants
and can handle difficult to treat effluents. To further
extend our capabilities, we also partner with Huber of
Germany for special wastewater treatment projects.
Our M2M framework allows us to deploy customized
solutions to increase the OEE (overall equipment
efficiency) of boilers, chillers, compressors, power
plants, sugar mills, water and wastewater treatment
plants, printing presses, solar energy installations, etc.
In conclusion: more and more people are willing to invest
in technologies that are environment friendly.
Businesses also realize that an environment sensitive
approach appeals to many customers and stakeholders.
Government is too playing an important role by stricter
enforcement of environmental laws. A.T.E. and our
customers have already worked together in so many
cases where we have implemented green solutions that
also help the bottom line! I am sure the articles will give
you more ideas.
With best wishes,
Anuj Bhagwati

Driven by passion and commitment,
A.T.E. embarked on a long term plan
for its clean technology business in
2006 to provide innovative solutions
for sustainable development. It soon
built-up a range of solutions in the areas of air, water and
energy – the three critical components of sustainability.
Within a short span of time, A.T.E. has established itself
in these domains with differentiated technologies, thus
standing apart from other players in the field.
Here is an overview of A.T.E.'s clean technology
solutions:

affordable lifecycle cost.
A.T.E.’s clean technology solutions
The first of the original products that HMX has introduced
is the HMX-Ambiator, with its patented dry air moist air
(DAMA) heat exchanger technology. It is a significant
upgrade over air-washer (single stage evaporative
cooling technology) in the sense that it either 'saves
power for the same cooling effect as an air-washer' or
'provides more cooling and comfort than an air-washer'.
Also with HMX-Ambiator, moisture addition in
conditioned space is less than 50% as that of air-
washers.
Recently we have launched a range of pre-cooled fresh
air units, the HMX PCU-F and HMX PCU-R. The HMX
PCU-F is designed to reduce air-conditioning
tonnage. It can be deployed either as a standalone unit
or in conjunction with a cooling coil to precool fresh air
most efficiently without an expensive and complicated
return air system. It is ideal for fresh air induction in
hotels, hospitals, auditoriums, malls, multiplexes,
commercial complexes, etc.

6. HMX launches PCU-F and PCU-R for comfort air-
conditioning
HMX has launched its range of high-efficiency,
environmentally-friendly, pre-cooled fresh air units, the
HMX PCU-F and HMX PCU-R, to satisfymfresh air
requirements for the industrial and commercial sectors.
HMXPCU-F
The standard HMX PCU-F consists of an air filter, our
patented dry air moist air (DAMA) heat exchanger, an
optional coil (direct expansion – DX or chiller water –
CHW), supply air fan and its motor. The unit is then
connected to ducts that supply the clean pre-cooled
fresh air to the air handling unit or directly to the
conditioned space. DAMA works on the principle of
indirect evaporative cooling (IEC) for sensible cooling of
the primary air using water. The primary air is cooled
without adding moisture to it and in the process the dry
bulb temperature and the enthalpy of the fresh air are
reduced substantially. This helps to reduce the total
tonnage (TR) requirement for the project, and saves
a large amount of energy that is otherwise required
to condition the ambient air. This machine is available
from 500 CFM to 20000 CFM in standard options, and
can also be customized to suit project requirements.
The objective of HMX PCU-F is to reduce compressor
load for once-through applications.
The HMX PCU-F is an excellent option where the entire
fresh air load is handled by the chiller or a DX system. In
these cases, the retrofitting of the existing fresh air
handling unit is also possible. The total cooling capacity
TR saved will vary from one location to another.
For example, in Pune, the savings in compressor
energy consumption is nearly 20% over the course
of a year!
The PCU-F can be used in various sectors like
pharmaceuticals, hospitals, hotels, theatres and even
applications such as process cooling or to retrofit the
existing fresh air unit. Here the air is passed only once
through the space due to which there is zero
contamination. Positive pressure is maintained inside
the room and hence, a separate exhaust system is not
required.
HMXPCU-R
The standard HMX PCU-R is normally a double-decker
arrangement consisting of an air filter, our patented dry
air moist air (DAMA) heat exchanger, a supply air fan and
it's motor in the upper deck. The lower deck comprises
an air filter, a return air fan and its motor, and a plenum.
Arrangement is made such that the cold return air, by
design available at room temperature of 24°C and 55±5
% RH, is used as secondary air for DAMA.

7. HMX PCU-R is available in sizes from 500 CFM to 6000
CFM.
The objective of PCU-R is to replace inefficient and
maintenance intensive energy recovery wheels, heat
pipes, air-to-air heat exchangers, etc. with a more
efficient and economical solution that is both reliable and
sustainable. The annual energy savings with the
PCU-R is substantially higher to the tune of 50–60%
as compared to the existing options for energy
recovery devices!
The PCU-R can be used for varied applications such as
pubs, shopping malls, IT industries, offices, commercial
complexes, etc., where pre cooled fresh air is needed
and return air is available. Here, a retrofit is not possible
and a separate exhaust system is required to carry the
return air to the PCU-R.
M2M-based remote monitoring of stack emission &
air quality
The Ministry of Environment and Forests (MoEF) has
made it mandatory for industries to display emission data
in the public domain, through a local electronic board &
also on the company’s website.
EcoAxis has developed a very cost effective remote
monitoring solution which helps industries comply with
the Pollution Control Board (PCB) norms by
continuously monitoring and displaying air quality
parameters.
The full solution comprises remote display of
parameters, including an interface with the PCB website,
as well as alerts to plant operators & managers in case
the set limits are breached. The solution provides data
transmission in compatible formats as prescribed by
Central Pollution Control Board (CPCB) as well as
individual state PCBs.
It also provides data access to PCB/company personnel
to view historic data (any time, any place) over an
internet connection using a secure username and
password. This data can be viewed in MS Excel, PDF,
tabular, and graphical formats. This solution has so far
been successfully implemented in multiple thermal
power plants, and EcoAxis will be shortly taking this
solution to steel & cement plants as well.
Anaerobic technology for efficient treatment of API
effluent
The rapidly growing API (active pharma ingredients)
industry faces many challenges in treating their
wastewater. The wastewater from API units typically
contain variety of chemicals, many of which are also
known to be refractory (or difficult to biodegrade). Also
their product mix changes frequently, hence the
wastewater chemical characteristics also vary
significantly over the period. It has been a challenge to
the industry to ensure that the treated effluent not only
meets the norms, but also be suitable for recycle in
process and non-process uses.
Conventionally, aerobic biological processes have been
used along with physico chemical primary and/or tertiary
stage. There have been rare instances of use of
anaerobic treatment processes as a part of API
wastewater treatment process. However, many such
installations were having operational problems which led

Mahindra & Mahindra delighted with HMX Ambiator
HMX has successfully commissioned a 32,000 CFM
Ambiator at Mahindra & Mahindra, Nagpur in February,
2014. Mahindra & Mahindra (M&M) is the largest tractor
manufacturer in the world (by volume). The
manufacturing plant on Hingana road, Nagpur, rolls out
90,000 tractors per year.
The factory management faced a lot of problems with the
40 TR chiller units on the tractor assembly shop floor
installed earlier. Though the system proved to be
adequate for cooling the machines, the air handling units
8
failed to provide comfort to the workers. Additionally, the
motors and blowers of the air washer systems at other
locations of the factory were susceptible to rusting.
That's when they decided to approach HMX. Based on
HMX's study of the plant layout and recommendation,
M&M decided to modify the existing ducting layout and
install a HMX Ambiator of 32,000 CFM. After
experiencing the excellent cooling effect provided by the
Ambiator, the management decided to put the 40 TR
chiller unit on standby. This has resulted in M&M
saving around 31 kW/hr by using the HMX Ambiator.
Hence, not only did M&M get excellent cooling, but it also
got a system that is energy efficient! This is the largest
blow throughAmbiator installation in India.
The management is quite impressed with the HMX
Ambiators and has decided to replace two more
chiller units in the same factory, as the first Ambiator
far exceeded their expectations.
