main components
Water Condensed Versions
DX Units water condensed .W. .Q. .F. .D. are equipped with an
AISI 304 brazed plate condenser. Units are supplied fully tested
and charged with POE oil and refrigerant. During the nal factory
test, all operating parameters are measured and memorized,
they are available on request. According to water T [city water]
it is possible / needed to add a 2 way condensing control valve
[Fig. 5]. In case that it is not possible to reduce the water ow,
ooding technology is the alternative: in this case only refrigerant
side actions occur and the water ow remains constant.Fig. 5
The condenser is located behind the compressor compartment
and is fully reachable from the front of the unit.
Fresh Air Kit
Fresh air kit consists of a exible pipe and a cartridge G3 lter
and under normal conditions ensures roughly 150 m3/h inde-
pendently from the unit's model. In down ow units the lter is
located in the fans section and before removing the lter it is
necessary to stop the unit and to remove the sheet metal of the
fan's compartment. In up ow units an additional booster fan is
provided to ensure roughly 80m3/h for all models and the relative
lter is located just close to the main lter.
Plenum Kit
Suction/delivery plenum with 300mm and 500mm height are
available. In case of down units such plenums can be equipped
with silencers cartridges, damper section for Direct free-Cooling,
high efciency lters. In case of up ow units the delivery plenum
can be tted with aluminium grills frontal air discharge [Fig.6]
Base Frames / Floorstands
Made in galvanized steel, are available in three different heights
: 300, 500 and 800mm, with excursion +/- 25mm.
Electrical Heaters
Made in aluminium with a large surface for keeping the lowest
possible surface temperatures [less than 130°C]. They are
realized for 3 steps operation. Each elements is provided with
independant safety thermostat. Despite the very small depth
of the unit, the elements are mounted in a special rail order to
extract them from the front of the units. This is possible with all
DH models, Up and Down ow. Before any maintenance on
electrical heaters, disconnect the units from power supply and
wait for 30 minutes, allowing the temperature to decrease.
