AIR COOLED SELF-CONTAINED
Integral Self-Contained
(Models OHS-012/040-AS)
The system shall be a self-con-
tained, ceiling mounted supple-
mental air conditioner with
factory mounted integral air
cooled condenser with centrifugal
blower.
The condenser shall be sized to
provide the total heat of rejection
of the system at a 95°F DB ambi-
ent temperature.
The system shall require only
single point supply power con-
nection and the system shall ship
from the SATS factory with a full
operating refrigerant charge.
DX - EVAPORATOR SECTIONS
Air Cooled Remote Evaporator
(Models OHS-( )-()AR)
The system shall be a remote
(split) air cooled, ceiling mounted
supplemental air conditioner
evaporator. The evaporator sec-
tion shall house, as a minimum,
the evaporator coil, expansion
valve, compressor, evaporator
blower/motor and associated
electrical and refrigeration compo-
nents.
The OHS-( )-()AR evaporator
section shall be located at some
distance from its correspond-
ing CeilAiR model HES-( )-()CAA
indoor or WCS-( ) outdoor air
cooled condenser.
The evaporator system shall
require only single point main
power supply connection and the
ystem shall ship from the SATS
factory with a dry nitrogen hold-
ing charge ready for field refriger-
ant (R-22) charging.
(Note: SATS Condensers & Condensing
Units can be found in our "Heat Rejec-
tion" engineering manual.)
DX - WATER COOLED SYSTEMS
Integral Self-Contained
(Models OHS-( )-W / DW)
The system shall be a self-con-
tained, ceiling mounted supple-
mental air conditioner to include
integral water cooled, coaxial
condenser with factory installed
head pressure water regulat-
ing control valve(s). Condenser
(source) water shall be provided
by a cooling tower or some other
remote water source.
The system shall require only
single point supply power con-
nection and shall ship from the
SATS factory with a full operating
refrigerant charge.
Water Regulating Valves:
Head pressure shall be auto-
matically controlled by a factory
installed 2-way water regulating
valve rated for 150 psig w.w.p.
(Note: 3-way and high pressure 300 to
400 psig rated valves are available as op-
tions, page 3-9.)
DX - GLYCOL COOLED SYSTEMS
Integral Self-Contained
(Models OHS-( )-G / DG)
The system shall be a self-con-
tained, ceiling mounted supple-
mental air conditioner to include
integral glycol cooled, coaxial con-
denser with factory installed head
pressure glycol regulating control
valve(s). Condenser (source) gly-
col solution shall be provided via
a CeilAiR model GPS-( )-( ) / HES-(
)-LGA remote glycol pump pack-
age and drycooler system.
The system shall require only
single point supply power con-
nection and shall ship from the
SATS factory with a full operating
refrigerant charge.
Glycol Regulating Valves:
Head pressure shall be auto-
matically controlled by a factory
installed 2-way glycol regulating
valve rated for 150 psig w.w.p.
(Note: 3-way and high pressure 300 to
450 psig rated valves are available as op-
tions, page 3-9.)
CHILLED WATER AIR HANDLERS
CHILLED WATER SYSTEM
(Models OHS-( )-C)
The system shall be a ceiling
mounted chilled water supple-
mental air conditioner to in-
clude chilled water cooling coil,
evaporator blower and motor
and chilled water control valve.
Chilled water shall be provided by
a remote liquid chiller system.
Chilled Water Control Valve:
Cooling capacity shall be con-
trolled with a slowly opening and
slowly closing 2-way motorized
control valve rated for 300 psig
w.w.p.
(Note: 3-way 300 psig motorized valves
and 2 or 3-way modulating valves are
available as options .)
