| Many
industrial fluid cooling applications pose a special challenge. Often
the fluid to be cooled would attack the materials of construction
of the cooling equipment or the flows and temperatures are outside
the range of normal operation. A properly sized heat exchanger can
allow standard cooling equipment to operate within its parameters
while providing the required cooling to a process stream at very different
conditions. A corrosive process stream, for example, could
not be cooled from 100° F to 50° F directly by a chiller.
By employing a heat exchanger and creating a secondary liquid loop
through the heat exchanger and a chiller, the chiller could operate
to cool the secondary liquid loop from 55° F to 45° F and
the secondary loop could cool the process stream on the other side
of the heat exchanger as desired. The result is the thermal and hydraulic
separation of the process and the cooling equipment so that the desired
cooling can be delivered with readily available equipment.
Rental heat exchangers are available in individual sizes from 40
to 2,800 sq. ft. of surface area and can be combined in multiples
to meet almost any heat transfer requirement. Heat exchangers of
brazed plate, plate and frame, and shell and tube construction
are available to match the correct construction to the application.
Materials are commonly carbon steel, stainless steel and titanium
for maximum corrosion resistance in harsh environments. |
