CAICE Attenuator

Typical Construction Code
Example:
SG02V / 3C / B / SM / B2 / X
A rectangular attenuator with splitter elements, constructed from
galvanised sheet steel.
The unit shall be delivered to site split in two sections in length,
and splitters shall be installed in the vertical plane.
The unit casing shall have a high pressure rating, with 30mm
profile flanges at both ends. The attenuator shall be protected
by bubble wrap.
The attenuator shall be provided with side splitters and the infill
shall be protected by Melinex polyester film. The unit shall have
a base colour polyester powder paint finish on external surfaces
only. The unit shall also have a special feature.
Construction Code Format
The first three sections of the construction code, up to and
including the packing are always shown:

Optional features, paint options and special features are only
shown if applicable, and in the order as they are shown in the
construction codes layout on the previous page.

Other Materials
This brochure only provides details on attenuators constructed
from galvanised sheet steel. However CAICE can also provide
attenuators constructed from a range of other materials where
required:
Stainless steel - for duct systems handling corrosive chemically
laden air, or with high standards of cleanliness, or for external
applications, etc.
Plastic - for duct systems handling corrosive chemically laden
air, etc. Various types of plastic are available depending on the
application.
Heavy duty galvanised steel - for industrial applications, or
where casings need to be welded for very high pressure duct
systems, etc. Rolled steel angle (RSA) flanges would normally
be provided for these types of application.
Generally attenuators can be constructed in these materials to
the same sizes as the standard galvanised sheet steel products
that are detailed in this brochure. However if you require more
detailed information on attenuators constructed in alternative
materials then please contact our sales personnel for further
assistance.
Fire Rating
All CAICE attenuators detailed within this brochure are capable
of maintaining their internal air circulating area when subjected
to an internal temperature of 300° C for a period of 120 minutes.
These attenuators are therefore suitable for installation within
smoke or heat exhaust systems, providing the internal
temperature does not exceed 300° C for a period longer than
120 minutes.
Warrington Fire Research have undertaken an independent
assessment and compiled a report that supports this statement.
For more onerous conditions or where proprietary systems, such
as Flameshield are specified, matching attenuators can also be
provided by enhancing the constructional specification of the
products.
Fire rating is a diverse topic, and therefore if you do require
more details on the attenuator options that we can provide then
please contact our sales personnel for further assistance.
