Our modular concrete
cooling solution offers Water Chilling plants and
Flake Ice Plants for the construction industry.
Flake ice machines
are in capacities ranging from 10 TPD to 45 TPD
of ice. A continuous operation without a harvest
cycle results in less refrigeration capacity required
to produce a ton of ice as compared to any other
type of manufactured ice with similar specifications.
All water used by flake ice machines is converted
into ice, hence, waste or spillage is avoided.
Single stage Kirloskar KC Compressors with Ammonia
are used for 10 & 20 TPD at an evaporating temperature
of
-18 Deg C (-4 Deg F). For other capacities two stage
internally compounded KC compressor operates at
an evaporating temp of -25 Deg C ( -13 Deg F) thus
giving faster cooling and higher capacity of flakes.
On mixing water with cement used in concrete, due
to the exothermic chemical reaction between cement
and water heat is liberated which is known as the
heat of hydration. During the curing process this
heat of hydration raises the temperature of mass prepared
by up to 25°, causing an increase of volume. After
curing process the concrete cools down again reducing
its volume and thus naturally causing cracks. Therefore
the initial pouring temperature of mass should be
lowered so much that the maximum temperature during
the curing process does not exceed a certain temperature
determined.
In construction of dams, tunnels, bridges, and sewage
plants etc; it is of utmost importance that temperature
of the green concrete is controlled so that these
buildings can withstand tensions that are created
in finished concrete structure. Excessive internal
heat-up of the green concrete especially in hot climates
has to be avoided in order to prevent cracks and maintain
proper strength, ensure consistent quality, and eliminate
cracks.
