Powerful <strong>ELCO</strong> boilers for new<br />
residential complex.<br />
Green Hill is a new residential complex with a total area of<br />
over 200,000m 2 . Residential complex that currently under<br />
construction will include 40 buildings.<br />

The challenge<br />
Initially, traditional fire-tube boilers were considered for this project<br />
but after the construction company learned about the advantages<br />
of modern boilers, they decided to choose <strong>ELCO</strong>. Five TRIGON®<br />
XXL SE 1900 boilers with a total output of 9.2 MWt were installed in<br />
a standalone boiler plant room that will provide heating and DHW<br />
for the whole residential complex. This is the most powerful project<br />
<strong>ELCO</strong> has been involved with in Russia, as the company's boilers are<br />
used mostly for rooftop installations, as opposed to the standalone<br />
plant room in this application.<br />
Comment<br />
During construction of the complex, much attention was paid to<br />
environment legislation. <strong>ELCO</strong> boilers are fully compliant with this,<br />
as they meet the highest requirements regarding emission levels.<br />
At first, the boilers were working on LPG before they were then<br />
converted to natural gas without any additional accessories. <strong>ELCO</strong><br />
TRIGON® XXL SE boilers have a 1:4 modulation ratio which will allow<br />
them to operate in optimal mode and maintain power according to<br />
actual heat load - even during the initial phase, when only a small<br />
number of houses have been built and occupied.<br />
TRIGON® XXL SE — Class-leading<br />
outputs with extremely low emissions.<br />
The TRIGON® XXL offers unrivalled power<br />
and performance, delivering outputs up to<br />
2 MW, thanks to a one-of-a-kind boiler design.<br />

The <strong>ELCO</strong> solution<br />
Powerful boiler plant room with cascade of five<br />
TRIGON® XXL SE 1900 boilers. As the boilers will be<br />
part of a large system, it was decided to use plate<br />
heat exchangers to protect them. Thanks to the<br />
<strong>ELCO</strong> boilers' low emission levels, it was possible to<br />
use short flue chimneys.<br />
