The YAES-SA (QPak-sa) range are single
packaged air cooled chillers. The larger
cooling capacity YAES-DSA (QPak-dsa)
are manufactured in two sections, with
integrated controls, to facilitate transport
and lifting.
There are two product families, standard
units and low sound units, which are
equipped with semi-hermetic twin helical
screw compressors and microprocessor
controls to provide high full and part load
efficiencies and reliable performance.

and SOUND PRESSURE LEVELS
The optional low sound version (Sonata) has an acoustically treated enclosure that
contains compressors, valves and piping systems and has specially designed low
sound two speed fans.
YAES-DSA units have a communications link, that must be plugged together,
between the two panels and a mixed liquid sensor that must be installed in the
common leaving liquid pipework from the two evaporators. All units are designed for
roof or ground level locations.
