Aerzener Maschinenfabrik GmbH 7 Stephan Brand / 04.10.2010
1. Why Delta Hybrid?
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%!

Energy efficiency in wastewater treatment plants:
Source: CEE + EPA
Aerzener Maschinenfabrik GmbH 8 Stephan Brand / 04.10.2010
Energy efficiency in wastewater treatment plants:
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

What makes this rotary lobe
compressor unique?
2. Technical features
WEFTEC 2010
Aerzener Maschinenfabrik GmbH 17 Stephan Brand / 04.10.2010
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

2. Technical features
WEFTEC 2010
Aerzener Maschinenfabrik GmbH 22 Stephan Brand / 04.10.2010
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.
