DSA WALL – Wall Mounted Station
General description and |
|
|
|
Danfoss district heating substations provide the |
||
|
|
|
||||
application |
|
|
|
link between district heating suppliers and cus- |
||
|
|
|
|
tomer installations. They contain all the necessary |
||
|
|
|
|
equipment to adjust the heat supplied for the |
||
|
|
|
|
needs of the object premises as specified in the |
||
|
|
|
|
heating supply contract. In this respect they must |
||
|
|
|
|
comply with all applicable standards and with the |
||
|
|
|
|
supplier’s technical connection conditions. Indirect |
||
|
|
|
|
connections (in which district heating and in-house |
||
|
|
|
|
systems are hydraulically isolated) incorporate |
||
|
|
|
|
components that separate the systems (heat |
||
|
|
|
|
exchanger), limit the flow volume to that specified |
||
|
|
|
|
in the contract, regulate the secondary supply tem- |
||
|
|
|
|
perature and measure energy consumption. |
||
|
|
|
|
The DSA WALL is designed for use in high-param- |
||
|
|
|
|
eter district heating networks. It is suitable for heat- |
||
|
|
|
|
ing single and multifamily homes, and commercial |
||
|
|
|
|
and industrial buildings. It offers an alternative |
||
|
|
|
|
solution to oil or gas boilers. The DSA WALL is pre- |
||
|
|
|
|
pared for heating, domestic hot water and floor |
||
|
|
|
|
heating applications. Its wall-mounted construc- |
||
|
|
|
|
tion allows for the space saving needed for instal- |
||
|
|
|
|
lation and servicing. |
