WEFTEC 2010


Absolute reliability!

Easy operation and maintenance, reduction of the

maintenance costs!

Low sound level!

efficient…

More efficient!

Increase of the energy efficiency, increase of the

machine-efficiency!


Today‘s market requirements on blower units:

WEFTEC 2010



waste water and water treatment plants are accounting for approx. 3% of

the U.S. electricity use!

the usage equates for approx. 100 billion kWh annually!

the total electricity costs are approx. 4 billion US$/year!

the plants are responsible for a production of approx. 45 million tons of

greenhouse gas (GHG)!

the national energy saving potential is estimated in the range of 15-30%!

WEFTEC 2010

Energy efficiency in wastewater treatment plants:

Source: CEE + EPA



in plants producing digester

gas, about 50% of the

electricity is used for aeration

Smaller plants without a

digester use 60 to 80% of the

electricity for sludge aeration

The Delta-Units made by Aerzener have set a market standard

with its driving-concept and are known on the world market as

product brand made by Aerzener.

WEFTEC 2010


Positive displacement blowers since 1868 + screw compressors since 1943

= the worldwide first rotary lobe compressor!

WEFTEC 2010


What makes this rotary lobe

compressor unique?


WEFTEC 2010


7 patents and patent application make Aerzen’s

Delta Hybrid the most innovative compressor!

Examples:

Patented performance increase by pulse-charging and twiste rotors

to minimize „squeeze losses“

New seal system (internal and at the drive shaft) significantly

reduce wear

Patented bearing systrem with nominal bearing life > 60.000 O.H.

(at p = 15 psi / 1000 mbar)

Highly efficient discharge silencer without absorption material

New suction taper reduces inlet pressure losses


WEFTEC 2010


Isochoric compression: type -L

Aerzen’s Delta Hybrid compressor stages combine the

operating principle of…

Twisted 3+3 rotor profile

Positive pressure to 12 psi / 0.8 bar

Vacuum to -18 in Hg / – 0.6 bar


WEFTEC 2010


Internal compression: Type -S/-H

Twisted 3+4 rotor profile

Positive pressure to 15 psi (-S) or 22 psi (-H)

Vacuum to -21“ Hg (– 0.7 bar)


WEFTEC 2010

Aerzen’s Delta Hybrid compressor stages combine the

operating principle of…


Aerzen Hybrid 3+3-Rotary Lobe Compressor uses the patented

pulse charging to increase rotor chamber filling to more than

100% therefore significantly improving the overall efficiency!

WEFTEC 2010


Other features that enhance efficiency:

Very wide flow control range from 25% to 100%

Optimal air flow management within the acoustic hood: cool air enters

the compressor (= increased efficiency)

Optimized fluidic design of inlet and discharge ports

Reduced pressure losses in the discharge silencer

Special silencer insulation help maintain a low sound enclosure

temperature (= increased compressor efficiency)

IE2 high efficiency (Standard) or IE3 premium efficiency (Option) motor

Power fluctuations even under varying inlet temperatures

(summer/winter operation) or discharge pressure (diffusor aging or

fouling) are minimal compared to turbo compressors.

WEFTEC 2010



Robust and durable design

Patented bearing system; > 60.000 o.h. at 15 psi (1000 mbar)

Oil change intervals extended to 16 000 o.h.

New, internal pulse reduction

WEFTEC 2010



Belt drive for exact-sizing

(= energy efficiency)

Fully automatic bet tensioning

(= reduced maintenance costs)

Selection between electric motor or

shaft-driven cooling fan

Optimized sound enclosure

Oil level monitoring from outside

Side-by-Side installation

Flexible instrumentation, Aerzen

controller AERtronic optional

WEFTEC 2010


Inlet cone reduces noise emission and

minimizes the pressure loss of the inlet

silencer and filter


WEFTEC 2010


Discharge silencer / base frame combination without

absorption material with broad-band 4-flow system lower

the noise level induced into the downstream piping.
