Commitment to our planet earth
There is widespread anxiety today concerning damage
to the environment due to industrial and commercial
activities. In particular, there is a global awareness
about the destruction of the earth’s protective shield, i.e.
the ozone layer, caused by Chlorofluoro Carbons
(CFCs) & similar other man-made gases, some of
which are used as refrigerants in Refrigerating System.
However, at Kirloskar the future is indeed in safe hands
since we ensure that environment friendly processes are
adhered to from designing, manufacturing to
commissioning of a refrigeration system. Further, over
the years, it has become our undeclared policy to
promote Ammonia as refrigerant, which is the most
eco-friendly refrigerant having zero global warming
potential (GWP) and zero ozone depletion potential
(ODP).
At present, Ammonia is a preferable refrigerant since it
is a natural substance. There is a downside though.
Firstly Ammonia is toxic and secondly it is combustible.
Due to its pungent smell, Ammonia is a self-warning
refrigerant in case of minor leaks too. By wearing
protective mask and gloves during maintenance work
the possibility of health hazards can be totally
eliminated. Further number of accidents on account of
using Ammonia as refrigerant, as supported by official
records, is very low.
At Kirloskar, we know that with our good design,
careful selection of components, safety devices, proper
installation and service procedures none of the above
obstacles are insurmountable.
Thus, we always remain committed to a safer and
healthier world for all of us.
