parallel flow of the
product.
2. Seal cooler designs
facilitates to vent the
product and water with
minimum effort.
3. Seal cooler is designed to
be cleaned and
reassembled after being
in service.
1. Seal cooler allows more
than one configuration to
accommodate various
operating requirements.
2. Complete draining of the
product and coolant side
ensures no vapor lock
situation resulting in high
efficiencies.
3. Scaling and cooler fouling
can reduce cooler
efficiency over a period of
time. 682 Seal Cooler can
be disassembled and
washed effectively
resulting in increased
efficiency time after time.
