and switches for monitoring pressure,

temperature, speed, oil level, and filters

to ensure dependable operation and

enable remote monitoring of critical oper-

ating paramaters.

Inlet/Outlet silencers

Inlet and oulet silencers come standard.

Washable and reusable polyester inlet

filter protects the blower from damaging

particulates. Filter media has low flow

resistance to minimize pressure drop and

the filter differential pressure is displayed

on the Sigma Control 2.

V-belt drive with guard

V-belt drive provides flexible pressure/

flow combinations and dependable per-

formance. Drive efficiency is maintained

by our automatic v-belt tensioner. Our

fully-enclosed belt guard offers complete

Communications CapabilitiesIntelligent control and protection

To protect your investment and ensure

the most efficient operation possible, we

control these integrated screw blower

packages with our Sigma Control 2™.

This intelligent controller comes standard

with multiple pre-programmed control

profiles so you can select the one that

best fits your application.

Sigma Control 2 monitors a wide

range of operating parameters, shuts

the unit down to prevent damage, and

signals if immediate service is required. It

also tracks preventive maintenance inter-

vals and provides notice when PMs are

due. An RFID sensor provides secure

access and simplifies managing mainte-

nance intervals.

An SD card slot with included SD

card enables fast, easy software updates

and offers long-term data storage for

analyzing energy consumption and blow-

er operation.

Sigma Control 2 has superior com-

munications capabilities. An Ethernet port

and built-in web-server enable remote

viewing. ModBus, Profinet, Profibus,

Devicenet, and other industrial commu-

nications interfaces are also available as

plug in options for seamless integration

into plant control/monitoring systems.

Kaeser’s Sigma Air Manager (SAM)

can control up to 16 blowers and only

turns them on when needed to meet air

demand. This improves pressure stabil-

ity, reduces energy use, and equalizes

blower run time.

SAM can monitor any 4-20 mA

sensor/sensing device for system control.

It constantly monitors the system demand

and selects the most efficient combina-

tion of units to meet it.

Whether a fixed speed or variable

speed blower, SAM knows the specific

performance of each unit and keeps

them running in their optimal operat-

ing range to maximize energy efficiency

while minimizing drive losses at lower

operating speeds.

Sigma Air Manager also provides

blower status messages and alarms to

help minimize down time. Using SAM’s

communications capabilities, you can

remotely monitor operating status, main-

tenance schedules, and energy usage.

Sigma Air Control Plus

Sigma Air Control Plus is a combination

of data storage hardware

and analysis software that

enables you to continuously

record and review your sys-

tem’s function and energy

usage. Sigma Air Control

Plus can give you exten-

sive information about your

plant’s operation, including

graphic profiles of system pressure, air

flow, machine load/unload, activity, duty

cycle, and power consumption. This con-

tinuous system data acquisition helps you

analyze plant operations and optimize

energy efficiency.

Sigma Frequency Control

This fully integrated variable speed

drive provides continuous blower speed

adjustment to match the process flow to

the demand. Kaeser matches the blower

block, drive motor, and variable speed

controller for optimal specific perfor-

mance over a wider range of flows. This

ensures maximum efficiency in multi-unit

operation while always meeting fluctuat-

ing demand.

Superior Efficiency Options

Kaeser Start Control

The Sigma Start Control (STC) provides

reduced current starting (wye-delta) for

fixed speed units. The package is also

equipped with premium contactors, over-

load protection, and phase loss monitor-

ing.

Kaeser’s screw blowers are available with an integrated

reduced voltage wye-delta starter or variable frequency drive.

Extremely low sound and vibration

All EBS and FBS models feature a stan-

dard enclosure that is built for excep-

tional noise reduction and easy access to

maintenance points. Heavy gauge con-

struction and a powder coat finish make

it suitable for both indoor and outdoor

installation. Heavy duty dampers absorb

vibrations and reduce stress on plumbing

and wiring. Sound levels are as low as

70 dB(A).

Parallel Cooling Concept

Kaeser’s screw blower package design

separates airflows for the blower, motor,

and electrical cabinet. This ensures air is

not preheated before entering the screw

blower, which keeps the overall efficiency

higher. It also means the coolest pos-

sible air is being channeled across the

drive motor. A dedicated fan guarantees

cooling air is flowing though the main

enclosure and electrical cabinet regard-

less of the operating speed of the pack-

age.
