5.1 Description
In this system the collector is made out of plastic pi-
pes with a special pipe head. This vaporizing system
requires smallest space of all ground vaporizers. The
bore-hole diameter is 125mm, the depth and collec-
tor length depend on the heat pump output. The brine
mixture circulates inside the pipes. The heat exchan-
ge between the brine and the coolant happens inside
the vaporizer set with a stainless steel plate heat ex-
changer.
For the brine circuit connection is required: A brass
manifold with gate valves, safety blow off, manome-
ter, pressure vessel, thermometer and brine circulati-
on pump.
The enclosed flexible connection pipes have to be
used to avoid any noise conduction. The connection
between manifold and heat pump has to be built on si-
te, whereby it is not allowed to use any galvanized pi-
pes!
5.2 Range of Application

* The given collector depth is an average value and is depending on the condition of the ground.
** For the bore-hole collector: Type of pump: xx-xx = Grundfos UPS, xx/xx = Wilo Top S
*** Brine mixture (= 30% Proportion of anti-freeze), without contents of the collecting line
Connecting on Site: It is not allowed to use any gal-
vanized pipes! The enclosed flexible connection pi-

The used anti-freeze has to be permitted by IDM-
Energiesysteme GmbH.
The brine circuit pipes have to be insulated with a
suitable and diffusion proof insulation against con-
densing water.
Brine circulation pump and pressure vessel have
to be installed onto the flow.
The brine pressure vessel has to be connected
above the pipes.
The circuits have to be filled with the anti freeze
mixture from the pressure vessel on (because of
volume reduction at temperature drops during
operation)
The pipes have to rise for venting
