Introduction
The SSB Retractor is a pneumatically operated targeted spray ball which has been designed to
achieve fast effective cleaning of all equipment used in the production process, including
Ductwork, Vent Lines, Cyclones and many other applications where access is impossible
This manual has been prepared as a guide for the persons who will be operating and maintaining your
tank cleaning machine. The key to long life for your tank cleaning machine will always be a system of
carefully planned maintenance; you will appreciate that a tank cleaning machine which has a rough
and dirty job to do will need more frequent attention than one working in ideal conditions.
It is in your own interest to get the best and most economical performance from your tank cleaning
machine. Neglect of maintenance means poor performance, unscheduled stoppages, shorter life and
expense. Good maintenance means good performance; no unscheduled stoppages and better total
economy.
You will find the information contained in this manual simple to follow, but should you require further
assistance, our Customer Service Department and world-wide net of Distributors will be pleased to
help you. Please quote the type and serial number with all your enquiries; this will help us to help you.
The type and serial number are placed on the side of the body of the tank cleaning machine.

ATEX Marking
The SSB Retractor - Mini Retract-A-Ball is certified as category I components. The certification is
carried out by the notified body Baseefa, who has issued the certificate Baseefa 11ATEX0231X. The
marking on the ATEX certified SSB Retractor - Mini Retract-A-Ball is as follows:
Note:
TE75P231-04 and TE75P251-04
These machines are approved for 180°C max: Tamb -10°C to +180°C.
Changes to the machine are not allowed without approval by the person responsible for the ATEX
certification at Alfa Laval Tank Equipment A/S. If changes are made – or spare parts other than Alfa
Laval original spare parts are used - the EC Type Examination certification (the ATEX Directive) is no
longer valid.

Design Overview
The unit has been specifically designed to ensure good self draining so that there is no hold up of
cleaning media after operation; this is achieved by a sealed cleaning housing and telescopic actuation
and air cylinder design which ensures the minimum surface area becomes wetted. No media enters the
spring chamber. After operation the SSB Retractor can be held open pneumatically while the spray
stem self drains before closure by the return spring. This provides the opportunity to purge the spray
stem if required.

Applications
The SSB Retractor can be used to clean from simple tanks and ductwork, to complex process
applications with agitators where it is not possible to use fixed spray balls. Applications such as
Storage Tanks, Reactors, Mixers and Spray Dryers including Ductwork and Vent Lines can all be
cleaned by use of one or multiple SSB Retractor units.
ATEX
Warning: The speed at which the Sprayball is deployed (extended to the open position) must
not exceed 0.5m/s. Ensure that the control air pressure is regulated to 4 bar max.
Options
The units are available in a range of operating strokes. As standard there are two sizes of SSB
Retractor—60mm and 120mm. However, both units can be adjusted during manufacture by increments
of 10mm. This allows the units to be fine tuned to accurately position the spray ball optimising the
effectiveness.
As standard the units are available with all machined components in 316L Stainless Steel and standard
seals in EPDM and Carbon filled PTFE. However, the units are available with wetted components in
Hastelloy C22 and seals manufactured from Perfluorolastomer should the environment require.
The spray balls are offered with standard spray patterns or can be target drilled to direct cleaning to
certain features such as access covers etc.

Accessories
The unit can be supplied with proximity sensors to indicate that the unit is either fully open, fully closed,
or both. If this option is required, a sensor part number: TE75P507 will be required for each position.
If the SSB Retractor is being ordered with ATEX Certification it is important to note that if a sensor is
fitted the ATEX Category & Zone in which the SSB Retractor can be used will be effected.
The SSB Retractor is ATEX Category 1 but if sensors are fitted the unit will assume the lower ATEX
rating of the Proximity Sensor.
If sensors are required for an ATEX environment please consult Alfa Laval.
ATEX
Warning: It is important to note that the SSB Retractor is ATEX Category 1 for installations in
zone 0/20.
However, if Proximity sensors are fitted the overall ATEX rating of the SSB Retractor
will assume the lower ATEX rating of the proximity sensor.

Installation
The SSB Retractor is mounted to a 2" ISO Ferrule using the 2" ISO gasket and clamp supplied.
The unit must be mounted so that it is a minimum for 5ºabove horizontal. This is important to
allow the Home Chamber to drain when cleaning has finished. See Figure 4.

General Safety and Installation Instructions
Note: The machine shall be installed in accordance with national regulations for safety and other
relevant regulations and standards.
Precautions shall be made to prevent starting of the cleaning operation, while personnel are inside the
tank or otherwise can be hit by jets from the nozzles.
In EU-countries the complete system must fulfil the EU-
Machine Directive and depending of
application, the EU-Pressure Equipment Directive, the EU-
ATEX Directive and other relevant
Directives and shall be CE-marked before it is set into operation.
Warning:
If the machine is used in potential explosive atmospheres, tapes or joint sealing
compounds which are electrical insulators must not be used on threads or joints, unless
an electrical connection is otherwise established to ensure an effective earthing. In
addition, connecting pipe work, must be electrically conductive and earthed to the tank
structure. The resistance between the nozzles and the tank structure should not exceed
20,000 Ohm. This is essential to avoid the build-up of static electricity on the machine.
For further information see DS/CLC/TR 50404:2003 Safety of Machinery, guidance and
recommendations for the avoidance of hazards due to static electricity.
Electrical equipment such as magnetic valves and electric actuators must not be installed in Ex-zones
without type approval and marking, corresponding to the EX-class in question.

Temperature
ATEX
Warning: Atmosphere/surface temperature:
In potentially explosive atmospheres, the temperature must not exceed the maximum
surface temperature according to the temperature class for the combustible gas or
liquid.
ATEX
Warning: Steam cleaning:
Tanks with capacities greater than 100 m3that could contain a flammable atmosphere
should not be steam cleaned, as steam issuing from a nozzle could contain charged
droplets.
Tanks smaller than this may be steam cleaned providing that: the steam nozzles and
other metal parts of the system are r
eliably earthed and grounded to the tank
structure.
Pressure
Avoid hydraulic shocks. Increase pressure gradually. Do not exceed 4 bar inlet pressure.
Recommended inlet pressure: 2-4 bar. High pressure in combination with high flow rate will increase
consumption of wear parts. High pressure will also reduce the cleaning effect.
ATEX
Warning: Steam cleaning pressure:
If stream cleaning is done through the machine, the steam pressure must not cause
the machine to rotate.
ATEX
Warning: Draining:
If the machine is drained using compressed air, then the compressed air pressure
must not cause the machine to rotate.
