DECIDAMP®RTD
This installation guide provides recommendations to
maximize the service life of Decidamp RTD for rail track
applications.
KEY INSTALLATION REQUIREMENTS
• Ensure rail track surface is clean, free of dirt or other obvious
contaminants before installing.
• Decidamp RTD can be installed without the use of contact paste.
• If contact paste / adhesive is specied we recommended the use of
Decidamp DX is used.
• Rail should be free of large quantities of moisture (eg. rain water).
• Installation can be done over rust.
TRACK IDENTIFICATION MARKINGS
• Consideration should be made for rail identication markings.
• Damper can be removed to reveal identication marking.
• If completely obscured, method of identifying the markings
location is recommended.
• If adhesive contact paste is used, preventing removal of rail
damper, rail identication should be transcribed to plaque, and
attached to external face of Decidamp RTD.
INSTALL PREPARATION
• Each Unit installed shall consist of:
• 4 Decidamp RTD dampers
• 8 Decidamp RTD Clips
• Decidamp DX contact paste if specied by contractor
• Each damper to be spaced 700 mm apart
PRIOR TO INSTALLATION
• Materials should be stored adequately as per TDS/SDS.
• Dampers should not be exposed directly to weather or
outdoor elements prior to installation, as best practice.
• Contact paste should not be allowed to freeze.
APPLICATION OF DECIDAMP RTD CLIP WILL REQUIRE
• A dead blow hammer.
IF APPLYING CONTACT PASTE YOU WILL REQUIRE
• Plural mixing pump for bulk quantities.
• A 2 mm V-notch trowel.
• Each damper will require 25 grams of contact paste.
• For use on rail supported on sleepers, slab track
or non-embedded vignole rail.
• Maximizes benet of low or medium resilient rail
pads and fasteners.
• Reduces airborne noise generated by rail track,
and allows complete rail system design to reduce
ground-born noise, vibration in track & sleepers.
• Avoid the application where any of the following
obstructions are:
• Welding joints
• Cable connection points
• Other rail mounted xtures
AREA OF APPLICATION
Pyrotek oers rail dampers to reduce radiating
noise from railway rolling stock.

WORKING HEALTH AND SAFETY
• Suitable personal protection equipment (PPE) should be used during all methods of installation and maintenance. Refer to the materials safety
datasheet to determine the appropriate PPE to be used.
• Suitable care must be taken to avoid damage to adjacent materials and nished surfaces.
DAMPER INSTALLATION
• When specied, apply contact paste mixed in quantity
supplied, to curved surface of Decidamp RTD. Use a 2 mm
V- notch trowel to spread evenly, resulting in a nominal 0.5 mm
applied thickness.
• Contact paste should be applied at temperatures above
0 °C, as below this it may not harden. Application at 20
°C to 30 °C will provide a 10 minute pot life. Applications
at elevated temperatures (above 30°C), working time
is shortened, and installation is not recommended or
warranted.
• Place damper in location where installation required, a damper
should be installed on each side of the rail, on both rails.
• At mid-point between sleepers. For example, at 700 mm
centered spacing.
• Perform visual inspection to ensure blocks are correctly
tted to the curvature of the rail prole.
• Rail shall remain xed by fasteners during installation.
• Place clips in conguration shown
• Clip should be at least 20 mm from edge of the Decidamp
RTD damper.
• Use installation tool or dead blow hammer to impact lower end
of clip, so that clips fasteners hook to the foot on the other side
of the rail track. See picture 2
• Visually inspect that clip is correctly installed and that damper
is rmly in place. Proceed with next damper.
REMOVAL OF DAMPER
• Removing the damper without the use of contact paste can be
easily done by using a lever such as a pinch bar.
• Clips must be replaced once removed. Dampers can be reused
if removed in good condition.
• If contact paste and clips were used during installation, clips
can be removed as above, and damper should be removed
using a mallet and chisel. Dampers and clips cannot be reused
if installed with contact paste.
