NORDIC® EMDX Pit Heat Exchanger Layout
Diagram at left shows another possible
configuration for a horizontal DX piping
system.
•
Each loop should encompass about
230 m
2
to 325 m
2
of land area per
“ton” of heat pump.
•
Each loop consists of 107 m of 13
mm copper tubing.
•
The “pit” could be a excavated area
or an existing area which needs to be
filled as part of general excavation.
•
Loops should be buried approxi-
mately 2 m underground for best
performance.
Example:
Nordic DX-45 should have (3)
loops as shown at left, a DX-55
(4) loops and a DX-65 (5) loops.
Other configurations would work as well
such as a 15 x 15 m pattern or a 18 x 14
m etc.
The object is to encompass at least the
minimum area mentioned above with
spacing no closer than 2.5 m between
any two pipes.
