SARAVEL Remote <strong>Air</strong><br />
<strong>Cooled</strong> Coondensers<br />
aare<br />
available in<br />
12 modelss<br />
in the rangge<br />
of 3 to 100<br />
Tons for air-conditiioning<br />
and refrigeratiion<br />
applicationns,<br />
and can be configureed<br />
into a wiide<br />
range of coompressor-eevaporator<br />
coombinations<br />
for<br />
halocarbonn<br />
refrigerantss.<br />
The easee<br />
of installatiion<br />
and minimum<br />
maintenaance<br />
makes SARAVEL aair<br />
cooled ccondensers<br />
ideal for year rouund<br />
applicationns<br />
in multistoory<br />
office buuildings,<br />

industrial ffacilities.<br />
<strong>Air</strong>-cooled condenserss<br />
operate drry<br />
and do nnot<br />
require insstallation<br />
of pump and water pipinng.<br />
These unitts<br />
are also aavailable<br />
for industrial fluuid<br />

air-cooled condensers are designeed<br />
for<br />

When selecting<br />
a sitee<br />
for<br />
installationn,<br />
the folloowing<br />
guidelines<br />
shouldd<br />
be<br />
followed:<br />
1.The outtdoor<br />
locatioon<br />
of the uunit<br />
should have<br />
minimumm<br />
sun expossure<br />
and an adequate supply<br />
of fresh aair<br />
without any<br />
obstructioons.<br />
2. Do not install units beneath winndows<br />
or betwween<br />
structurees<br />
where noormal<br />
operatting<br />
sounds may<br />
be objecctionable.<br />
3. Units ccan<br />
be instaalled<br />
either on a roof oor<br />
on<br />
ground leevel.<br />
4. The coondenser<br />
fanns<br />
are of thhe<br />

CLEARANNCES<br />
The unitts<br />
must be<br />
installed with suffficient<br />
clearances<br />
for air entrrance<br />
to the ccondenser,<br />
ffor<br />
air<br />

and<br />
snow acccumulations<br />
are expeected,<br />
addittional<br />

FOUNDATTION<br />
The unit should be mmounted<br />

DATA secction.<br />
Roof Loccations<br />
– Select<br />
a sitee<br />
with adeqquate<br />
structural strength of thhe<br />

Neoprene type isolatoors<br />
should be<br />
incorporatted<br />
to<br />
minimize the transmmission<br />
of vvibration<br />

Ground Leevel<br />
Locationns<br />
– It is crittical<br />
that the units<br />
will not seettle,<br />
causing strain on the<br />
refrigerantt<br />
lines<br />
and resultting<br />
in possibble<br />
leaks.<br />
The pad shoould<br />
be isolaated<br />
from the e main buildding<br />
foundation too<br />
prevent thee<br />
transmissio on of vibratioon.<br />
For ground level installlations,<br />
prec cautions shoould<br />
be taken to protect the uunit<br />
from being<br />
tamperedd<br />
or<br />
causing injuury<br />
to unauthhorized<br />

wire – messh<br />
guards, oor<br />
louvered panels, shoould<br />
enclose the units.<br />

Furthermoree,<br />
for propper<br />
return of oil to the<br />

the refr rigerant vapor<br />

be maaintained<br />
at a minimumm<br />

and 1500 0 fpm in vertical<br />

When the ccondensing<br />
unit is loca ated below the<br />
evaporator, the pressurre<br />
drop due to vertical rrise<br />

be heeld<br />
less than n 40 psi in orrder<br />
to prevent rrefrigerant<br />

On a systemm<br />
where the evaporator is s located below<br />
the condenssing<br />
unit, thee<br />
suction line e must be sizzed<br />
for both presssure<br />
drop and<br />
oil return.<br />
All horizontaal<br />
suction lines<br />
should be e pitched in the<br />
direction of the refrigeraant<br />
flow to aid<br />
the returnn<br />
of<br />
oil to the compressor. . All suction n lines withh<br />
a<br />
vertical rise exceeding 66m<br />
should ha ave a “P” trapp<br />
at<br />
the bottom and the toop<br />
to facilit tate oil retuurn.<br />
Suction linees<br />
with a veertical<br />
rise exceeding e 6. 5m<br />
should be trrapped<br />
everyy<br />
6m to provide<br />
drain poiints<br />
for the oil wwhen<br />
the cirrcuit<br />
is de-activated.<br />
Whhen<br />
the circuit is re-activatted,<br />
oil will return to the<br />
