The <strong>ELCO</strong> solution<br />
The heating system requires a delta T of<br />
30K and at the same time a high systemside<br />
water pressure of 6 bar due to the<br />
building's height. Furthermore, only two<br />
chimney flues with a height of 42m were<br />
available. Here, the TRIGON® XL was able<br />
to demonstrate its full performance and<br />
robustness. Coupled with <strong>ELCO</strong>'s HEX³<br />
stainless steel heat exchanger and the<br />
low flue gas emissions, a long-lasting and<br />
efficient system was created.<br />

with physical disabilities.<br />
From the heating centre in the basement of the<br />
16-storey building, the surrounding properties are<br />
supplied with heat.<br />
The challenge<br />
The existing boiler was defective and leaking. Therefore, the<br />
defective 2,300kW boiler had to be replaced at short notice, while<br />
the remaining 2,300kW boiler also had to be renewed. A CHP<br />
(combined heat and power) with an electrical output of 300kW<br />
remains installed in the central heating system, which should be<br />
hydraulically integrated into the new set-up and optimise running<br />
time. A combination of cramped conditions in the central heating<br />
system, the building's height of over 42m and the integration into<br />
the BMS (GLT) were all issues that had to be overcome.<br />
Comment<br />
The aim was to increase the efficiency of the boiler system in<br />
combination with the CHP unit and ensure reliability. For this<br />
purpose, we focused on a low starting output of the boilers when<br />
selecting the products and put together a cascade comprising<br />
several units. We then compared the TRIGON® XXL and TRIGON®<br />
XL and, together with the heating engineer and the customer, we<br />
decided on a cascade of 8x TRIGON® XL 570 instead of 4x TRIGON®<br />
XXL 1200.<br />
Featured products:<br />
TRIGON® XL<br />
The TRIGON® XL represents a significant<br />
step forward in heating technology.<br />
With extremely flexible configurations,<br />
clever design and a range of models<br />
available, the boiler is perfect for a variety<br />
of commercial applications. Plus, extensive<br />
cascade arrangements of up to 8 boilers<br />
with a combined output of 4,560kW are<br />
possible.<br />
