Partner for automation

Water technology

Your objective: Economy in plant engineering

and plant lifecycle management

Our solution: Competitive advantage

through complete automation systems

Energy prices today are high

and rising even further, forcing

you as municipal or industrial

operators of water and waste -

water treatment plants to take

action. In addition, the need for

modernisation and new building

that is needed in many cases

puts everyone, operators,

engineering consultants and

plant constructors, under

constant pressure to cut costs.

What is required is the

exploitation of potential

for savings in all lifecycle

phases of a plant, from plant

engineering through to

operation.

1. Engineering: decentralised

automation, clever concept,

reliable performance!

No matter where you are

implementing a major project,

our water segment specialist can

support you worldwide with the

development of reliable automa -

tion solutions. This can save

you time, money and resources

during the engineering phase

of both new building and

modernisation projects.

A decentralised automation

concept is for water or

wastewater treatment plants

more appropriate than a

centralised automation concept.

Because it is usually faster to

implement and commission, it

is easier and saves on resources

at the same time. And our

decentralised automation

solutions are also absolutely

reliable!

In a decentralised automation

concept, in addition to the power

cabinets in the control room,

smaller cabinets are placed in

a decentralised configuration

in the plant. The remote I/Os

installed and decentralised

PLCs inside them process the

electrical signals while valve

terminals activate the actuators

pneumatically. Flexible tubing

bridge the few meters that

generally separate the actuators

of the process valves.

The process control system

is still centrally configured. It

communicates with the remote

I/Os and valve terminals by

means of a continuous fieldbus

line such as, for example,

Profibus DP. Or over internal

Bus-Systems in case of a

decentralized process control. Air supply line Electric cable for position transmitter

2. Purchasing: all from a single

source, on the safe side!

Festo’s 59 national companies

and closely linked customer

service network in over 170

countries ensure that users can

be supplied at very short notice

with components and systems

for their automation projects.

Our standardised and globally

available product portfolio, with

everything from a single source,

not only makes the coordination

of your international activities

easier but also reduces the risk

of incompatible components.

3. Installation: “Plug and Work”,

time and money saved!

Automation systems from Festo

almost completely eliminate

the complex working processes

involved in the construction

of a system. Our systems are

rigorously tested and ready for

installation designed, to reduce

installation costs to a minimum.

4. Commissioning: easy, flexible

and fast!

Our automation concept makes

it possible to group together

individual processes on a decen -

tralised and modular basis, thus

allowing “dry” commission ing

long before the installation

of the master control system

or the electrical power supply.

With the addition of diagnostic

functionality for fast failure

detection, the way is clear

for inexpensive and fast

commissioning.

5. Operation and maintenance:

high plant availability, money

saved!

The standardisation of our

automation systems, together

with the training we offer for

your operating and maintenance

personnel, pays off in every

possible way. The results are

high plant availability, less

downtime and savings on

spare parts, logistics and

training costs.

Engineering

Quarter-turn actuators DFPB/DAPS

In many sizes, single- and double-acting,

8 to 8,000 Nm at 6 bar. With explosion protection.

SIL-certified.

Linear actuator DLP

For pneumatic actuation of knife gate valves

and sluices, up to 80,000 N at 10 bar.

With explosion protection.

Closed-loop controlled linear actuator DFPI

The all-in-one design of this actuator and

its technical specification make it ideal for

controlling knife gate valves and sluices with

closed-loop-controlled strokes: integrated

distance measurement by means of a

displacement encoder (potentiometer),

valve manifold, position controller and an

extremely robust connector.

Analogue sensor box SRAP

Position detector with 4 to 20 mA output

signal to monitor the full angle of rotation

of a quarter-turn actuator.

Digital sensor box SRBF

For detection and visualisation of the end

positions of quarter-turn actuators, even

under harsh operating conditions.

Accessories compressed air supply

Optimal pneumatic supply and connectivity.

Suitable for trouble-free operation of the

compressed air supply system.

Modular controller CECX-X-C1

Individual process solution with configurable

expansion options:

• Digital and analogue I/O devices

• PT 100

• Counter modules

• Profibus

CPX terminal

For integration of pneumatic and electrical

control chains. As valve terminal partner or

remote I/O unit. Open for all fieldbus and

Ethernet standards.

Valve terminal CPX/VTSA

For pneumatic and electrical power supply for up

to 32 valves. With regulators, flow control valves,

shut-off plates, switching position sensing and

pressure shut-off plate for “hot swap”

maintenance or repair work.

Valve terminal CPX/MPA

Space-saving system and function integration for

safe switching, free of reactive effects, of pilot

valves and process actuators, including pressure

sensors for process documentation.

Valve terminal CPV

Provides a communication link to all usual

fieldbus protocols. Can be used in combination

with a multiple pneumatic connector plate in

control cabinets or as a stand-alone device –

with a stainless-steel cover.

Front-end displays FED

Control of automation tasks at field level.

Graphics-capable for maximum flexibility when

displaying processes and data. For text-based

graphical development of visualisation solutions

for specific needs, e.g. recipe handling and

trend display.
