Efficiency champion

RADIAX® Technology
• Our industrialized world is immensely
dependent on machines for fluid and gas
transport, such as pumps, compressors
and fans.
• They use more than 50% of all generated
electricity.
• They can also be very noisy and they are,
together with the immense energy
consumption, a heavy burden on the
environment.
• That dependency demands that the
machines have to be very reliable and
have as little failure, maintenance or repair
as possible.
• The supply conditions have to be
guaranteed, whereby the designed
durability aims at a long continuous
operation.®

RADIAX® Technology
• A large amount of the machines that are
being used at the moment are insufficiently
aimed at a high efficiency and insufficiently
based on new, advanced technology.
• High quality new design knowledge can,
combined with accurate and innovative
production techniques, nowadays provide a
long durability and the utmost reliability.
• This development can be compared with
the development of a car: a modern car
barely has any maintenance compared to a
car of ten years ago.
• Centrifugal pumps are ‘the’ usual
workhorses for fluid transport, such as
water for the drinking water supply. They
work properly, but they have design
limitations.

RADIAX® Technology
• These limitations relate to the classic so
called operating point concept; when you
open wide the tap at home the water
pressure drops.
• More ‘flow’ unavoidably leads to lower
pressure.
• The pressure and flow of centrifugal pumps
have a similar fixed relation regarding
pressure and flow around the (design)
operating point.
• In other words: when you change the
resistance behind the main pump, by
changing the tap opening, then the
pressure changes, as well as the flow.
• Furthermore, the efficiency will drastically
decrease when deviating from this (design)
operating point for centrifugal pumps.

RADIAX® Technology
• Besides this limited working window, there
is also a large chance of damage to the
pump, such as erosion damage caused by
cavitation.
• Another limitation of a conventional
centrifugal pump is the pressure increase:
1,7 bar (per stage).
• To attain a higher pressure there are more
serially connected (stages) pumps needed.
• The RADIAX® pump of Bronswerk® Heat
Transfer brakes rigorously with the
limitations of the classic pumps.
• Designed for a fixed maximum pressure
and flow, the pump is completely variable
for both pressure and flow, from 0% to
100%.
• This goes independently of each other and
with a very high efficiency.

RADIAX® Technology
• The RADIAX®. pump does not show any
cavitation.
• Although the build-up from the pump is
centrifugal, functionally it behaves as a
volume displacement pump.
• The RADIAX® pump has a pump factor of
20; this means that the pump can bring
water from 1 to 20 bar in one stage.
• The RADIAX® pump offers unprecedented
possibilities: maximum flexibility with
minimal complexity.
• The weight and the volume are about the
same as one quarter of a conventional
centrifugal pump.
