only be used following consultation with
Krautzberger.

Krautzberger pressure containers are
equipped as standard with a material outlet
with shutoff device, compressed air connec­tion fitting with overpressure valve, and a
pressure gauge for pressure indication.

Pressure containers may be fitted with stir­rers, level gauges, filling devices and other
accessories.

Krautzberger 50-litre and 100-litre pressure
containers are designed for 10,000 stress
reversals (1 stress reversal (or load cycle)
is equivalent to a pressure fluctuation range
> 3bar).

When using hazardous substances:

When using hazardous substances,
note that the substance is released into
the atmosphere if the safety valve is ac­tivated.

1 Use for intended pur-

pose

Krautzberger material pressure containers
are containers with detachable covers in
which compressed air can be used to pres­surise liquid and low-viscosity materials.
The pressurised material can then be
routed via suitable hoses and pipes to ex­traction points (e.g. spray guns or similar).
Pressure containers are primarily used in
the painting and coating sector.

The temperature of the coating medium
may not be below -10°C or above +50°C.
Corrosive or highly abrasive materials may

2 General safety notes

Material pressure containers may
not be transported in pressurised
state!

The construction of pressure con­tainers may not be altered!

It is illegal to release certain hazardous
substances directly into the atmos­phere, and some substances may not
be present at the workplace in inadmis­sibly high concentrations. This means
that the safety valve must be of a de­sign that permits connection to a pipe­line, via which the hazardous sub­stances can be routed to a treatment
system if necessary. Krautzberger
pressure containers can therefore be
equipped with a safety valve with con­nection option.

Pressure containers may only be
operated within the operating pa­rameters (pressure, temperature
etc.) specified on the rating plate!

The housing of the pressure con­tainers is made of stainless steel
and may have galvanised or
enameled surfaces. The operator
must check the compatibility of
the materials with the coating
substances used. Please also re­fer to the instructions of the
manufacturer of the coating sub­stance.

2

Dokumentation

Before opening a pressure con­tainer, the compressed air feed
must always be shut off and the
container rendered pressureless
via the venting valve!

Stirring mechanisms must be
switched off and secured against
accidental switch-on!

Please always read and observe
the safety and treatment instruc­tions of the material manufacturer –
in particular instructions relating
to:

 the wearing of protective

equipment during the use
of hazardous substances

 the avoidance of harmful or

explosive environments

Electrostatic charges during opera­tion of the pressure container can
lead to electric shocks and spark
formation.

The pressure container must there­fore be earthed!

Air lines, material pipes and con­tainers, equipment and electrically
conductive surfaces in the working
zones must also be earthed.

Components connected by the op­erator (hoses and pipes, fittings,
extraction devices etc.) must be re­liably able to withstand the loads to
be expected during operation of the
pressure container (pressure, tem­perature, chemical and mechanical
influences).

Before each operating step, check
hoses and pipes for possible dam­age and ensure that they are firmly
connected. Loose, pressurised
hoses may cause accidents due to
whiplash-like movement and the
uncontrolled discharge of fluids.

DOK-315-GB.doc

Rooms in which hazardous substances
are stored or processed must have
adequate ventilation. It may be neces­sary to install a ventilation system.

If the ventilation system fails, work
must be stopped immediately and the
stirrer switched off.

Always comply with the relevant na­tional and regional regulations.

Do not store any flammable sub­stances, empty coating substance con­tainers or other materials that have
been in contact with the coating sub­stance (paper, cloths etc.) in the con­tainer or in the working zone.

Do not use halogenated detergents.
Chemical reactions may cause explo­sive and caustic compounds!

In the working zone, avoid open flames
and red-hot components as well as
equipment, tools and parts that can
create ignitable sparks.

Hang up “No Smoking” signs in a 5­metre radius of the container. Make fire
extinguishers available if these are not
already in place!

Comply with all national and regional
water protection regulations!

Comply with all national and regional
waste disposal regulations!

4 Installation, mounting of the container

Pressure containers must be installed in such a way that:

 neither employees nor third parties are at risk

 they are accessible for regular inspection

 the rating plate is easily visible

 the pressure container can be operated from a safe and stable position

 they are protected against external mechanical influences

 they are protected against unauthorised access

4.1 Connections

 Connect the material pressure hose leading to your extraction point to the material out-

let (4)

The material outlet can be located the bottom or routed through the container cover via a
riser pipe. The material outlet may have more than one port for the connection of more
than one consumer.

 Connect the compressed air feed to the air connection (6)

The compressed air supply must be dry and oil-free. Make the necessary provision for a
suitable shutoff device (ball cock).

The compressed air fitting can be equipped with more than one (if necessary adjustable)
outlet for the connection of additional consumers (spray gun, stirrer etc.).

 Connect the waste air line to the safety valve

 Connect the earthing device and earth all conductive components in the working zone

 Check firmness of all connections!

4.2 Filling

Each time before you fill the container:

 Shut off the compressed air feed

 Vent the container via the ball cock (8) until the container is pressureless

 Switch off stirrer – if present

Do not open the container cover until the container has been fully vented!

There is increased risk of fire when you open the cover! In the working zone, avoid open
flames and red-hot components as well as equipment, tools and parts that can create ignit­able sparks!

When removing the cover, make sure that the stirrer blades do not knock against the con­tainer wall, thus creating ignitable sparks.

5 Regular checks, maintenance

 Check the proper functioning of the safety

valve every time before you begin operat­ing the system! To test the valve function,
turn the knurled screw of the safety valve
to the left. If the valve does not blow off,
the pressure container must not be oper­ated until a new safety component has
been fitted!

 Check the air and material lines and their

connections for seal-tightness and firm
seat every time before you begin operating
the system.

 Before opening the pressure container,

check the cover gasket for soiling, wear
and damage.

Before opening a pressure container for all maintenance., servicing and cleaning
work on the open container, the air feed must always be shut off and the container
rendered pressureless!

Stirring mechanisms must be switched off and secured against accidental switch­on!

6 Cleaning, disposal

Clean the pressure container after use thoroughly using a suitable detergent. Ensure that the
sealing surfaces between container and container cover are clean.

Dispose of materials accumulating during cleaning (cloths etc.) through the appropriate chan­nels. Comply with the regulations of the local waste disposal authorities.

Comply with the safety instructions of the detergent manufacturer. Detergents may
be harmful to your health and be easily flammable!

Ensure that the detergent is compatible with the container materials!

11 Inspection by qualified experts

Pressure containers must be checked on a regular basis by qualified experts. The in­spection intervals depend on operational experience, the substances used, and the
outcome of previous inspections.

However, the following periods may not be exceeded:

 Internal inspection: every 5 years

 Pressure testing: every 10 years

 External inspection: every 2 years

Internal and external inspection must be performed after 5,000 stress reversals. Re­cord each startup and rundown of the container with a pressure fluctuation range >
3bar (equivalent to one stress reversal).
