Features and
Benefits
Air-to-Refrigerant Coil
The air-to-refrigerant heat exchanger is constructed of staggered
copper tubes with die-formed corrugated lanced aluminum fins.
The fins are then mechanically bonded to the tubes through ex-
pansion.
The coil is placed internal of the unit design for model
GEH to assure no fin surface damage during shipment,
jobsite storage, or installation.
The internal placement of the coil on the horizontal con-
figuration provides an option of a dual filtration applica-
tion. With dual filtration to the GEH unit, maintenance to
the filter is significantly less than with a single filtration
system.
The maximum working pressure for both the GEH and
GEV coils is 450 psig. It is designed for maximum capac-
ity with an additional benefit of physical unit size reduc-
tion.
Coil specifications for both GEH and GEV may be found on
in the General Data section on page 48 of this catalog. See
Figure 19 for internal air to refrigerant coil placement.

Sound Attenuation Package
Testing of conventional units has iden-
tified that the sound radiated by the
casing of the unit is an important com-
ponent of the sound that reaches occu-
pants, especially when the unit is
located directly over the occupied
space.
This sound reduction package reduces
radiated noise from the cabinet. Trane
double-isolates the compressor and
single-isolates the co-axial coil in the
unit. This design absorbs the vibration
that contributes to radiated sound
For sound critical spaces, an
enhanced sound package as de-
scribed in Table 2 provides additional
attenuation.
Complete sound data taken in accor-
dance with ARI 260 is available for all
1/2 through 5-ton units. The test data
reflects multi-speed fan motor along a
single system curve. (See sound per-
formance data on Page 107.)
