Demand Flow – Your key strategy
for more energy efficiency
Chiller plant optimization that reduces energy consumption
by 20 to 50 percent.
Powerful solution
Demand Flow is specifically designed
for centrifugal and screw-type chilled
water systems and already has been
improving many central plant perfor-
mances, yielding energy savings of
20 to 50% and a total plant perfor-
mance with an EER up to 10.7.
As a holistic approach for optimizing an
entire chilled water system, Demand Flow
controller’s specialized algorithms can
deliver chilled water system efficiencies to
any existing building automation system.
Entire system saves energy
The algorithms also assure that energy
is not shifted from one plant subsystem
to another, as in some other energy
conservation routines. Demand Flow
measures and verifies the total chilled
water plant energy usage to provide an
accurate report of total energy usage
before and after implementation.
Safety and comfort priority
Overall safety and comfort of occupants
are not sacrified in achieving Demand
Flow energy savings.
No compromise
for safety and comfort
Highlights
■
Increases the deliverable
tonnage of the chilled
water plant
■
Simplifies plant operations
without sacrificing comfort
■
Allows plant to more accu-
rately maintain optimal
differential system pressure

If energy shifting is needed,
net impact still saves energy
constantly growing. For our customers, success is defined
by how well they manage these challenges. Siemens has
the answers.

Answers for infrastructure.
Our world is undergoing changes that force us to think
in new ways: demographic change, urbanization, global
warming and resource shortages. Maximum efficiency
has top priority – and not only where energy is concerned.
In addition, we need to increase comfort for the well-
being of users. Also, our need for safety and security is
