BOREAL
® ACDX Pit Heat Exchanger Layout
ONE LOOP PER “TON” REQUIRED
Diagram at left shows another possible
configuration for a horizontal ACDX
piping system.
⇒
Each loop should encompass about
2500 to 3500 sq. ft of land area per
“ton” of heat pump.
⇒
Each loop consists of 350 ft. of 1/2”
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 6 ft. underground for best
performance.
Example:
Boreal ACDX-45 should have (3) loops
as shown at left, a ACDX-55 (4) loops
and a ACDX-65 (5) loops.
Other configurations would work as well
such as a 50 ft. x 50 ft. pattern or a 60 ft.
x 45 ft etc.
The object is to encompass at least the
minimum area mentioned above with
spacing no closer than 8 ft. between any
two pipes.
