Data sheet
Welded District Heating Stations
Type DSE-D00 (distributor module, three secondary circuits)
General description and |
|
|
District heating transfer stations provide |
|
|
|
|||
application: |
|
|
the link between district heating suppliers |
|
|
|
|
and customers’ systems. |
|
|
|
|
They incorporate the necessary equipment |
|
|
|
|
to tailor the supplied heat to the needs of the |
|
|
|
|
object premises as specified in the heating |
|
|
|
|
supply contract. |
|
|
|
|
In this they need to comply with all applicable |
|
|
|
|
standards and with the supplier’s technical |
|
|
|
|
connection conditions. |
|
|
|
|
Transfer modules for system separation are |
|
|
|
|
described in a number of other data sheets |
|
|
|
|
(see also types H0 and H0WP). |
|
|
|
|
The system described here is a standard distributor |
|
|
|
|
module for secondary readjusted heating circuits. |

The heated and preregulated secondary supply |
For this purpose they incorporate electrical mixing |
water from the transfer module (e.g. H0 or H0WP) |
valves that ensure that the various heating circuits |
is fed into the heating circuit distributor. The |
receive optimal supply in accordance with the |
various outputs to the attached heating circuits |
appropriate temperature and/or timer programs. |
serve to adjust the heat supplied to them |
|
depending on their current requirements. |
