<strong>Dampers</strong>
<strong>Esscano</strong> <strong>Power</strong> are proud to offer complete damper system solutions for all types of industrial dampers.<br />
Our expertise stems from the Scan-Bi-Com company which was founded in 1976 and supplied both<br />
individual dampers and damper system solutions all over the World. In 2002 Scan-Bi-Com was acquired<br />
by <strong>Esscano</strong> <strong>Power</strong>, and our continual references display <strong>Esscano</strong> <strong>Power</strong>s´ International experience as<br />
damper suppliers, consulting engineers and trouble shooters for various damper applications.<br />
Our dampers are specifi cally and individually designed for the desired purpose. The units are supplied<br />
complete with comprehensive manuals for installation, commissioning and maintenance in accordance<br />
to our Quality Management Handbook.<br />
We supply: <strong>Dampers</strong>, individually designed for any application, manufactured from various materials<br />
including duplex stainless steels and fi breglass.<br />
We offer: Advice, design, manufacture, delivery, installation, commissioning, repairs and maintenance.<br />

General Introduction<br />
This brochure provides an overview of our product range for industrial dampers. We trust you will fi nd<br />
the information of interest and that you will consider us for your future damper requirements including<br />
replacement / refurbishment of existing damper installations, whatever make. Our aim is to provide<br />
total damper system solutions.<br />
Should you require literature covering the other business areas of <strong>Esscano</strong> <strong>Power</strong>, which include<br />
sales/service and maintenance of steam turbine plant, sales of valves, rupture discs and other<br />
instrumentation please contact us on DK: +45 4488 0070 UK: +44 1480 210601 or visit our Website DK:<br />

Design and Engineering Capabilities<br />
To ensure that our in house engineering experience is delivered to customers in the most<br />
effective way <strong>Esscano</strong> <strong>Power</strong> has invested in the latest technology tools. Our capabilities in<br />
design and engineering include:<br />
Solid Works<br />
All dampers are designed using Solid Works 3D modelling. This<br />
ensures the product is functionally correct and all of the produc-<br />
tion drawings will be fully in accordance with the designed damper.<br />
Cosmos<br />
Where necessary designs are interrogated using COSMOS fi nite element and Structural<br />
Design Analysis to ensure the optimum design to meet the customers requirements.<br />
Designs can be done in accordance with DIN, EN, DS, ISO, API standards.
Butterfl y <strong>Dampers</strong><br />
Single blade dampers.<br />
Used for on/off fl ow control.<br />
FLAP ISOLATOR and DIVERTER DAMPERS<br />
These dampers are typically used for isolation and gas-fl ow changeover operations. They are characterised<br />
by their very low leakage rates, achieving 99,98% sealing effi ciency per unit surface area. Our seal<br />
air pressure system with a highly effective fl exible metallic twin seal, ensures zero leakage in line with<br />
accident prevention legislation.<br />
Flap isolators and diverter dampers for fl ue gas desulphurisation plants are supplied in stainless steel<br />
or alternatively internal surfaces can be lined with glass fl ake or rubber coatings. These corrosion protection<br />
measures enable us to offer cost-effective solutions for applications involving one-sided exposure<br />
to aggressive gases.<br />
<strong>Esscano</strong> <strong>Power</strong> have developed their own special blade and seal system for operation in de-nox plants<br />
and systems handling dust-laden fl ue gas at temperatures above 400˚C. For gas turbine plants linked to<br />
waste heat recovery boilers, the isolator blades and inside the housing can be thermally insulated to<br />
minimise radiation losses.<br />
BUTTERFLY, LOUVRE AND BI PLANE DAMPERS<br />
These dampers are typically installed to isolate and control fl ue gases.<br />
Louvre <strong>Dampers</strong><br />
With parallel blade motion<br />
Used for isolation and fl ow<br />
control. The blades rotate in<br />
the same direction.<br />
Louvre <strong>Dampers</strong><br />
with Opposed Blade Motion<br />
Single blade dampers.<br />
Used for on/off fl ow control.<br />
Butterfl y Damper Ø500<br />
3-Way Diverter Damper<br />
For changing over gas fl ow<br />
or simultaneously isolating<br />
one duct.<br />
Louvre Damper 2000x2500<br />
Louvre Damper Ø3400<br />
Bi Plane <strong>Dampers</strong><br />
Two dampers in one. The blades<br />
are designed as hollow, which<br />
when closed and fi tted with seals,<br />
form compartments which can be<br />
pressurised with seal air. Biplane<br />
dampers with S3 or S5 seals are<br />
developed to provide a simple<br />
space saving method of ensuring<br />
zero leakage.<br />
Damper Types<br />
Guillotine<br />
For shut-off use.<br />
Flap Isolators/Non Return<br />
<strong>Dampers</strong><br />
For geometrical reasons these are<br />
two bladed and open towards the<br />
centre of the duct.<br />
