Apart from this, another compelling circumstance for use of roll bond evaporators was that as per The Montreal Convention, 1987, on Environment, to which India was one of the participants, had emphasized that gases which tend to deplete ozone layers in the atmosphere should not be used.

Taking into consideration all these factors, respondent No. 2-Company decided to switch over to the use of roll bond evaporators in the refrigerators. As it did not have the necessary expertise to manufacture the roll bond evaporators in its factory, it decided to purchase the same from outside sources.
