The Turblex single-stage, integrally-geared compressor

is the world’s most efficient. With thousands of units

operating worldwide, it has developed an unparalleled

record of long-term reliability and maintenance-free

performance. In fact, the Turblex single-stage compressor

is so efficient that most older compressor installations can

be replaced by Turblex units with the cost of replacement

recovered in a few short years by power savings.

• Variable flow with turndown to 45% (or less) at

constant speed.

a d va n ta g e S a n d C a pa C i t y

• Highest efficiency is automatically and continuously

maintained over the entire turndown range, including

off-design ambient temperatures and pressures where

units most often operate.

• High-quality bearing construction results in exceptionally

long life with minimal maintenance.

• Guaranteed oil-free air delivery.

• Compact design saves floor space and facilitates the

replacement of older, less efficient compressors.

Compressor air requirements that exceed 60,000 scfm per

unit employ “large unit construction” with enhanced support

structure for the larger volute casing. Depending on

capacity and size, the unit may be fitted with an integral

or separate gearbox.

All components in the air stream are aerodynamically designed to

minimize turbulence, thus streamlining flow through the compressor.

fig.7,8: Turblex impellers are milled from solid, forged billets of the highest grade aircraft

alloy, using five axis, numerically-controlled milling machines. The exact impeller shape is

determined from a computerized database of thousands of previously tested compressors

and ongoing aerodynamic design improvements. Thus, each new impeller incorporates all

previous test data, ever-increasing the overall efficiency.

fig. 9: Flow control is achieved by adjusting 17 to 21

non-symmetrical airfoil shaped diffuser vanes (VD),

arranged radially around the periphery (discharge side)

of the impeller.

fig. 6: Inlet air is continuously and automatically pre-rotated

by 13 to 24 non-symmetrical airfoils, arranged radially

around the concentric inlet, thus maximizing efficiency

throughout the operational range. The vanes are

supported at both ends, an unusually strong and

long-lasting configuration.

fig. 5 (below): The aerodynamically designed concentric (annular) air inlet cavity decreases

in cross-sectional area as air approaches the impeller. In concert with the variable inlet

guide vanes (IGV), this geometry creates a “whirlwind” effect, pre-rotating and uniformly

accelerating the air approaching the impeller.

Figure 10 illustrates the unusually efficient output of

the Turblex compressor. A unique “dual-point control”

operational model combines the efficiency optimizing

inlet guide vanes (IGV) with a set of variable diffuser vanes

(VD). These dual vanes simultaneously and continuously

modulate. An algorithm, contained in the programmable

logic controller (PLC) of the local control panel (LCP), is

responsible for directing modulation of these variable

vanes, based on changes in inlet temperature, differential

pressure, and discharge capacity. These are the three

variables that affect machine efficiency.

p e r f o r m a n C e

fig. 10: Efficiencies of various blowers/compressors. Dashed curve illustrates where

turndown may be limited.

fig. 11: Performance curves for the same application using inlet

guide vane or inlet butterfly valve capacity control (blue lines)

are compared to a Turblex dual vane unit (red lines). In this case,

the end-user required operation to 37% of maximum capacity.

The inlet guide vane unit would have been required to blow-off

air to avoid surging in the lower range (to the left of Point 1). The

Turblex unit was not only able to turn down to this low volume,

but was more efficient over the entire turn-down range.

As illustrated in figure 11, the Turblex dual vane compressor

has a performance curve (red lines) that is very steep

(almost vertical) and backward leaning as pressure rises

to surge. Only small changes in capacity occur as pressure

changes. This is an important advantage, especially in

process applications where the same mass flow of air is

required over wide pressure changes [e.g. sequencing

batch reactors (SBR)]. Secondly, the dual vane surge

curve is almost flat across the entire turndown range of

100-45%. This provides very stable control at highest

efficiency across the entire turndown.

Speed increasing gearbox selection depends

on the compressor capacity, horsepower,

and type of driver. All Turblex gearboxes share

similar heavy-duty design features for unusually

long and maintenance-free operation.

• AGMA gear quality of 12 or better

• Multi-point, non-contact labyrinth seals

• Service factor of, at least, 1.8

• Cast iron housing ASTM A48 Class 30B

Turblex units have air/oil shaft seals that

incorporate an aluminum alloy labyrinth with

multiple slinger rings (diameter changes) on

the shaft that guarantees 100% oil-free air.

fig. 13: Model GL gearboxes are vertically split. The fast

shaft and overhung impeller operate between the first

and second critical speeds. An inspection plate allows

gearbox inspection without disassembly.

fig. 14: The heaviest duty GL500 horizontally split gearbox

operates below the first critical speed and features a

double helical “herringbone” gear.

fig. 15: Model GK gearboxes incorporate economical

roller bearing design. The smaller KA2 unit is splash-oil

lubricated and air-cooled via fins on the casing. The KA5

and KA10 units use a shaft-driven oil pump and external

cooler. All GK models have a small oil reservoir internal

to the gearbox.

fig. 16: Model GL gearboxes use the highest quality

hydrodynamic lubricated journal bearings for longer life

and minimum vibration. Bearings are constructed of

bronze, which results in cooler running bearings and

lower maintenance costs. Steel backed bearings are

optionally available.

Pressure oil lubricated journal and thrust bearings operate

with an oil film between the bearing surface and the shaft. This

prevents “metal to metal” contact and produces an almost

infinite bearing life. Lube oil is pumped from the integral oil

reservoir in the skid base through the air or water-cooled oil

cooler. The lube oil then passes through an oil filter and into the

gearbox bearings. After cooling and lubricating the bearings,

oil drains back into the oil reservoir through an opening in the

bottom of the gearbox.

Turblex offers several sound attenuation options:

Sound attenuation of a compressor installation is greatly

impacted by the in situ environment. For example, inlet and

discharge piping design can especially affect the sound level of

an installed system. Turblex can offer a variety of tools to assist

the design engineer including piping layout options and technical

papers on construction techniques to reduce noise emission.

Option 2: 89-93 dB(A)

Option 1, plus a sound blanket

around the compressor/gearbox

and a quiet duty motor.


Option 1, plus an acoustical enclosure around the entire skid.

fig. 20: A wide variety of sound enclosure designs can be provided for indoor

or outdoor installations, emitting sound levels below 80 dB(A). Note the air-

cooled oil coolers on top of the enclosures.

Careful selection of accessories and aerodynamic piping design yields even

greater energy savings of the entire package.

Inlet Filter/Silencer – A Turblex inlet filter/silencer connects directly to the

compressor inlet, which eliminates the inlet piping. This reduces sound levels,

inlet piping pressure loss, and greatly facilitates air filter replacement.

Discharge Cone/Silencer – The Turblex discharge cone/silencer (Evase’ stack)

completes the conversion of velocity to pressure energy in the most efficient

manner possible. Fitted with acoustical packing on the inside wall, it also

provides sound attenuation at the direct compressor outlet.

Blow-off Valve and Silencer – Electrically operated butterfly valve and silencer

is open when the compressor is off-line, and pulses closed after start-up to

gently bring the compressor on-line, thus minimizing power on start-up.

Discharge Check Valve – Used for prevention of reverse air flow, this valve is

important for smooth start-up, being gradually pushed open, as the compressor

comes on-line and builds up pressure.

Discharge Valve – Used for isolation and prevention of reverse air flow while

off-line, this electrically operated valve is closed while off-line and opens

during compressor start-up.

Flex Connectors – Inlet and discharge flex connectors isolate vibration and

unbalanced loads from the compressor casing.

The Turblex containerized compressor is a modularized,

self-contained unit. Set in place, connect the electrical

and the discharge piping, and that’s it; no compressor

building, no installation. The expense of a “brick and

mortar” compressor building is eliminated. It can even be

set next to the aeration cells to minimize large diameter

main air header piping.

All accessory components are furnished by Turblex

to minimize jobsite construction and installation labor.

The compressor local control panel (LCP), conveniently

positioned inside the container, is wired to all skidded

instruments. The main drive motor starter may also be

provided and wired inside the container.

Container Construction – Is similar to a standard shipping

container except all walls and floors are acoustically

insulated. This results in sound levels in the low 80’s, five

feet from the exterior.

Local Controls and Instruments – The LCP is mounted

inside the container. An optional ‘slave’ operator interface

on the outside wall allows compressor monitoring

and adjustment without entering the container. Safety

monitoring instruments are conveniently mounted on

the skid and located for ease of access, calibration,

and observation.

scfm, 8.0 psig, 100 Hp, during factory testing.

Inlet Filter/Silencer – A louvered container door protects

the compressor air inlet from blowing rain and snow. Inlet

air then passes across the two-stage inlet filters, the inlet

silencer, and into the blower inlet. Access doors on the

sides of the filter box allow easy removal and replacement

of the 2 × 2 ft. panel filters.

Other accessories – The electric operated blow-off and

discharge butterfly valves, air discharge cone/silencer,

discharge check valve, blow-off silencer, and flex connectors

are shipped loose for integration into the contractor-

installed discharge air piping.

Turblex compressors are provided with safeguards and monitors for

long-term, trouble free operation. Other instruments are available

to monitor compressor operation and include vibration and bearing

temperature monitors that are generally used on larger units.

Maintenance status monitors are available for inlet air filters, oil filters,

oil reservoir level, and reverse rotation. In fact, Turblex engineers

excel at providing custom-instrumented systems to meet specific end

user requirements.

C u S t o m i z e d l o C a l C o n t r o l S pa n e l S

The LCP with integral programmable logic controller (PLC) is generally

mounted on the skid with factory wiring of instruments. If the LCP is

remote (freestanding), instruments are factory wired to skid-mounted

junction boxes. All signals are available for interface with upstream

plant process computer systems, and include the following functions:

Start/Stop – Local or remote (automatic) control in accordance with a

specific start-up/shutdown sequence.

Monitor of Safeguards – Alarm of any safety monitor will cause

shutdown either on soft stop or emergency (immediate) shutdown. A

soft stop allows the blow-off valve to partially open before shutdown,

minimizing surge.

Efficiency Optimization – Aerodynamic flow through the compressor

is optimized to obtain the lowest possible power consumption with

changing compressor capacity, ambient temperature, or differential

pressure. The PLC contains efficiency optimization software that

simultaneously and continuously modulates the diffuser vanes and the

inlet guide vanes as these three variables change.

Operator Interface Screen Monitor – Advanced visual graphics are

displayed on a touch sensitive, full-color screen.

The MCP is the heart of the entire aeration system

and houses the job specific and custom designed

operating software. The MCP performs many

functions, including the three major control loops that

optimize performance.

• Air Header Pressure Control – Regulates the on-line

air compressor volume based on an air header set-point.

• Process Variable Control – This loop within a loop,

fine tunes each air flow set point, thus feeding the

proper volume of air to each aeration cell.

• Most Open Valve Control – Maintains the air flow

control valves in their most open position, ensuring

the lowest overall system pressure.

Other functions performed by the MCP include:

• Lead-lag compressor selection

• Air header blow-off valve algorithm

• System time delays

• Setpoint intervals

• System data acquisition and monitoring

• Data transmission to plant computer

A Turblex supplied air delivery system offers the design

engineer an opportunity to maximize efficiency of the

overall system by operating at the lowest air header

pressure and the minimum air volume to meet process

oxygen demand.

The air delivery system, designed to operate as an integrated

cost savings system, consists of:

Air Flow Control Valves – Modulating air flow control

valves must be properly sized to operate between about

20% and 80% open.

Air Flow Meters – Used to control air flow to each

aerated zone.

Dissolved Oxygen (DO) Probes – The process monitor is

generally dissolved oxygen and must be reliable and

long lasting.

a i r d e l i v e r y S y S t e m

Main Air Header Blow-off Valve – Start-up (evacuation of

water in aeration piping) and optimization are facilitated

by use of this valve. With an appropriate algorithm in the

MCP, overall system surge can be virtually eliminated.

Piping – Using conservative piping air velocities and low

pressure drop piping components minimizes air header noise

and pressure drop. Turblex facilitates overall aeration

piping layout by saving space and materials with optimum

aerodynamic piping design.

Single point responsibility by Turblex will ensure that

the entire aeration system is supplied with the properly

sized components. The system is then placed on line

by Turblex, and optimized to maximize efficiency with

minimal operator attention.

W o u l d y o u C a r e f o r a n u p g r a d e ?

The upgrade of aging aeration systems is a Turblex specialty. No

other company matches our expertise when it comes to taking on

this difficult task. Several alternatives are available and the proper

choice rests with the end-user’s desires, the cost of upgrade, and

operating cost savings.

Retrofit Instrumentation and Controls – Aging centrifugal compressors

may be mechanically functional, but valves, instrumentation, controls,

and oil lube systems need upgrade/replacement. Turblex will visit the

jobsite, inventory the compressors, and make recommendations for the

upgrade/replacement of the LCP, instruments and ancillary equipment.

Reuse or Replacement of Existing Compressors – A new Turblex

single-stage is provided, then one or two existing units are upgraded

for use as standby compressors as well as for peak demand periods.

Retrofit Existing Compressor Buildings – Because the Turblex

units have a smaller footprint than comparable equipment, our

engineering staff is experienced in custom designing single-stage

compressors to retrofit existing compressor buildings with minimal

piping modifications.

h y b r i d C o m p r e S S o r S o l u t i o n S

In some cases, a combination of different types of

compressor technologies may be most economical.

A multi-stage, with a lower first cost, albeit less

efficient, is “base loaded” or used as the standby

(spare) compressor. That is, the multi-stage, when

needed, is run at 100% capacity, where it is most

efficient and the Turblex single-stage compressor

then varies capacity to meet demand.

compressors used for variable process air flow control and one

operation. Each unit is 17,490 scfm, 8.8 psig, 900 Hp.

Q u a l i t y C o n t r o l a n d t e S t i n g

Turblex ISO 9001-2000 quality assurance procedures

and the customer’s own requirements, combine to form

the basis of a rigorous inspection/test program. With

efficiency being a key advantage of the Turblex single-

stage compressor, only the most complete and detailed

test program will suffice to prove performance on the

test stand. Likewise, the aeration system, as a whole, will

only accomplish peak power savings if it is designed,

tested, and operated as one combined system. Major

milestones of quality assurance and testing the entire

aeration system include:

• Torsional and Lateral Critical Speed Analysis.

• Manufacture/Assembly – Per ISO 9001-2000 standards.

• Compressor Performance Tests – Per ASME PTC-10.

• Completed Assembly Tests – Functional testing of all

components including blow-off and air valves, connected

to the LCP.

Our commitment to quality assurance, with testing

of the entire system, ensures the most efficient and

trouble-free installation.
