CapKold Cook-Chill Production Systems
Falling Film Evaporator Based
Chilled Water Production
General Description:
[Chilled Water Application & Sizing] A reliable and cost effective
source of chilled water is key to the rapid chilling of kettle cooked and
Cook Tank prepared foods and also a valuable resource in other food
prep and production applications. The sizing of a Falling Film Chiller
and supporting Refrigeration System is a function of the estimated
daily chilled water requirements for all applications.
Potential growth, future equipment additions, added production
shifts, physical layout and relationship of the Evaporator to production
areas will all impact proper sizing of Falling Film Systems.

CKFF Falling Film Chiller
Falling Film Chiller
Overview:
Falling Film Chillers (FFC) use evaporator
plate technology with compressor condensers to make chilled water. A FFC is
a box with a group of vertical evaporator
plates and a water reservoir. Unlike the
coils in an Ice Builder, which stores ice
around them, these plates make chilled
water on an on-demand basis.
FFC systems are sized based on instantaneous chilled water requirements unlike
Ice Builders, which are sized by total daily
demand. However, FFC have groups of
chiller plates within the unit which can
be separated into “circuits”. A circuit is
one or more plates supported by circulation pumps and a compressor condenser.
This has some advantages:
• The unit can be sized for growth up
front. One establishes the maximum
load expected in the future and
chooses the FFC accordingly. The
FFC is purchased with the initial circuit or group of plates in place, with
adequate pumps and refrigeration.
• As the customer’s chilled water demands grow and additional Tumble
Chillers or Cook Tanks are added for
additional product chilling capacity,
additional plates and supporting
compressor condenser capacity can
be added. The internal and system
recirculation pumps are replaced as
needed for the increased water flow.
• If supplied by CapKold, the additional compressor condenser would
be configured with the features
outlined as necessary for proper
operation with FFC. If supplied
by others, modifications may be
required for full compatibility with
the FFC. Contact factory for details.
• For purposes of evaluation the
energy requirements of Falling Film
Systems versus Ice Builders, keep
the following information in mind.
Ice Builders and their associated
compressor condensers are sized to
make ice at night, during off peak
rate hours, and are based on making
ice 12 hours per day. In contrast,
compressor condensers for FFC operate on demand as they sense the
water temperature within the Chiller
reservoir and the need to reduce its
temperature. The compressor condenser operates on demand, much
as your refrigerator does at home.
It monitors water temperature and
turns on and off as needed.
