Suction flow | any | kg/s |
Supply pressure | any | barg |
Kinetic efficiency | 13-70 | % |
Suction pressure[Pa] vs Suction flow[kg/s]
Any Coanda ejector has 2 main
dimensions and also 3 geometric dimensions and 2 other
thermodynamic supply parameters (pressure and temperature) in
order to control the flow and make the necessary adjustments or
each flow conditions and each customers needs.
The Coanda ejector is more complex flow device than a simple rotor
fan or blower therefore the flow characteristics is done by
adjustments of geometric dimension, pressure and temperature. The
input temperature is critical for the efficiency of the device.
The diagrams suction pressure [relative Pa] vs suction
flow [kg/s] for different "p" supply pressures [barg]
might have any possible working point.
Geometric configurations
Coanda ejectors S systems is
design as a group of A x B x C ejectors of same type,
coupled to work together.
The Coanda ejectors S systems might be design in any
working configuration that is fixed in a specific place or shape
following the customers specification:
The Dsystem 4x4 or similar is used for rectangular, squared or circular ducts, pipeline, channels, mines gallery, tubes or other cases when have to move large and very large flows of air or other fluids including steam and water.
The Dsystem 2x7 or similar is used to create fluid flow barriers. The system is designed to move large and very large flows of air or other fluids including steam and water.
The Dsystem 2x2x2 or similar is used to create high pressure for large flows. The systems is designed to move with high speed of large and very large flows of air or other fluids including steam and water.
