1. ERIKS operating companies
ECON Noise Diffusers are being delivered by several ERIKS operating companies on a worldwide
basis. In this manual these will be referred to as ‘ERIKS’, the individual terms of delivery of the
ERIKS operating company having executed the order are applicable.
2. Product description
The ECON Noise Diffusers are designed according the information on our website,
www.eriks.com and should be used in accordance with the applicable pressure-temperature rating
as stated on this website. Noise Diffusers are provided with a nameplate. The marking makes the
identification of the Noise Diffusers easier and contains:
- Figure number
- Limiting pressure and temperature
- ECON

3. Requirements for maintenance staff
The staff assigned to assembly, operating and maintenance tasks
should be qualified to carry out such jobs and in any circumstance, ensure personal safety
4. Transport and storage
During transport and storage the Noise Diffusers should be protected against external forces. The
Noise Diffusers should be stored in an unpolluted space and should also be protected against all
atmospheric circumstances. The temperature and humidity in the room should be taken care of, in
order to prevent condensate formation.

5. Function
ECON Noise Diffusers are designed to decrease the level of noise associated with steam or
compressed air trap cycles. By installing a Noise Diffuser a reduction of about 80% of the noise
can be expected, measured at 1 meter form the application. Also due to its simple and small
design the ECON noise Diffuser is easy to install and uses little space.
6. Application
The ECON Noise Diffuser dampens the sound caused by steam or compressed air trap cycles.
The Noise Diffusers are designed for standard operating conditions. For the use of extreme
conditions e.g. aggressive or abrasive media, it is recommended to mention this at the ordering
stage, to verify whether the Noise Diffuser is suitable. The installation designer is responsible for
the Noise Diffuser selection suitable for the working conditions. The Noise Diffusers are
unsuitable, without written permission of an ERIKS company, to apply for hazardous media as
referred into Regulation (EC) no 1272/2008.
7. Installation
During the assembly of the Noise Diffusers, the following rules should be observed:
- make sure, before assembly, that the Noise Diffusers were not damaged during the
transport or storage, are according request and are suitable for the job.
- before installing the Noise Diffuser remove the plastic covers placed on the connection
ends.
- make sure that the thread on the pipe are from the same standard as the Noise Diffusers
and also free from pollution.
- check materials, pressure and temperature and their maximum values.
- the equipment has an arrow or inlet/outlet designations. Be sure that the Noise Diffuser is
installed with the arrow pointing in the same direction as the flow. See for an example the
figure below.
- the Noise Diffusers should be fitted in such a way that the outlet is pointed at the floor or
other suitable enclosure. Do not install the Noise Diffuser in such a way that it may cause
an accidental exposure to the discharge.
- the installation area should have easy access and provide enough space for maintenance
and removing operations.
- the installation area should have the necessary fire extinguishing system to prevent
damage to the equipment due to over temperature/pressure cause by fire.

8. Maintenance
Before starting any service jobs, make sure that the medium supply to the pipeline is cut off,
pressure was decreased to ambient pressure, the pipeline is completely cleaned and ventilated
and the plant is cooled down. Always keep safety instructions in mind and take all personal safety
precautions.
During maintenance, the following rules should be observed:
- always keep personal safety precautions in mind and always use appropriate protection
e.g. clothing, masks, gloves etc.
- be alert that the temperature still can be very high or low and can cause burns.
- there are no internal components that require maintenance.
- check the Noise Diffuser on all possible leaking possibilities.
- check if all bolts and nuts, are still fastened.
- we recommend that Noise Diffusers are serviced as necessary. Noise Diffusers should be
checked periodically (at least yearly), to verify that they are operating correctly and to
clean the internal parts and strainer screen.
9. Service and repair
All service and repair jobs should be carried out by authorized staff, using suitable tools and user
shall use genuine parts.
- welding repair and drilling of the Noise Diffusers is forbidden.
- it is forbidden to replace the bolt, nut or packing when the Noise Diffusers is under
pressure.
There are no spare parts available for the ECON Noise Diffuser.
10. Safety notes
Allow time for the temperature to normalize after isolation to avoid danger of burns.
11. Troubleshooting
It is essential that the safety regulations are observed when identifying the fault.
12. Removal
Dismantled and rejected valves cannot be disposed with household waste. The Noise Diffusers
are made of materials which can be re-used and should be delivered to designated recycling
centres.
