FORM 201.19-EG4
• COPPER FIN CONDENSER COILS – The unit con-
structed with condenser coils which have copper ns.
(This is not recommended for units in areas where they
may be exposed to acid rain.)
• SERVICE ISOLATION VALVE: Service suction
isolation valve added to unit per system (Factory
Mounted)
• DX COOLER OPTIONS:
w 300 PSIG (21 Bar) Waterside Design Working
Pressure – The DX Cooler Waterside is designed
and constructed for 300 PSIG (21 Bar) working
pressure. (Factory-mounted)
w 1-1/2" Insulation – Double thickness insulation
provided for enhanced efciency.
w Flange Accessory – Consists of raised face
anges to convert grooved water nozzles to anged
cooler connections. Includes companion anges.
(Field-mounted)
w Flow Switch Accessory – Vapor-proof SPDT,
NEMA 4X switch, 150 PSIG (10.3 Bar) DWP, -
20°F to 250°F (-29°C to 121°C), with 1" NPT (IPS)
connection for upright mounting in horizontal pipe.
(This ow switch or equivalent must be furnished
with each unit). (Field-mounted)
• BUY AMERICAN ACT COMPLIANCE - In keep-
ing with the “Buy America Act”, products will be
comprised of 50% U.S. content and manufactured
(nal assembly) in the U.S.A.
• CONTAINERIZATION SHIPPING KIT - Additional
factory tted components for added unit strength.
For container shipping on Models 0098 - 0208 only
(Factory Installed).
• VIBRATION ISOLATION:
w Neoprene Isolation – Recommended for normal
installations. Provides very good performance in
most applications for the least cost. (Field-mount-
ed)
w 1" Spring Isolators – Level adjustable, spring and
cage type isolators for mounting under the unit base
rails. 1" nominal deection may vary slightly by ap-
plication. (Field-mounted)
w 2" Seismic Spring Isolators – Restrained Spring-
Flex Mountings incorporate a rugged welded steel
housing with vertical and horizontal limit stops.
Housings designed to withstand a minimum 1.0g
accelerated force in all directions to 2". Level ad-
justable, deection may vary slightly by application.
(Field-mounted)
• ALTERNATIVE CHILLED FLUID APPLICATIONS:
Standard water chilling application range is 40°F
to 55°F (4°C to 13°C) Leaving Chilled Water Tem-
perature. To protect against nuisance safety trips be-
low 40°F (4°C) and reduce the possibility of cooler
damage due to freezing during chiller operation,
the unit Microprocessor automatically unloads the
compressors at abnormally low suction temperature
(pressure) conditions, prior to a safety shut down.
w Process Brine Option – Process or other appli-
cations requiring chilled uid below 40°F (4°C) risk
water freezing in the evaporator, typically overcome
by using antifreeze. For these applications, the
system incorporates brine (ethylene or propylene
glycol solution), and the system design Leaving
Chilled Fluid Temperature must be provided on the
order form to ensure proper factory conguration.
Liquid injection included with this option.
w Thermal Storage Option – Thermal Storage re-
quires special capabilities from a chiller, including
the ability to ‘charge’ an ice storage tank, then pos-
sibly automatically reset for operation at elevated
Leaving Chilled Fluid Temperatures as required by
automatic building controls. The Thermal Storage
Option provides Ice Storage duty Leaving Chilled
Fluid setpoints from 25°F to 15°F (-4°C to -10°C)
minimum during charge cycle, with a Reset range
of 40°F (22.2°C) supply uid temperature. Liquid
injection included with this option.
• UNIT ENCLOSURES –
w Wire Panel Enclosure (Full Unit) – UV stabilized
black polyvinylchloride coated, heavy gauge,
welded wire mesh guards mounted on the exterior
of the unit. Protects condenser coil faces and de-
ters unauthorized access to refrigerant components
(compressors, pipes, cooler, etc.), yet provides free
air ow. This can cut installation cost by eliminating
the need for separate, expensive fencing. (Factory-
mounted)
w Louvered Panel Enclosure (Full Unit) – Heavy
gauge louver panels, galvanized and painted just
as the main unit cabinet, provide liberal free air
ow area. Cover coils and around the bottom of the
unit to protect condenser coils, visually screen me-
chanical elements, and deters unauthorized access
to refrigerant components. (Factory-mounted)
w Louvered Panels (Condenser Coil Only) – Lou-
vered panels are mounted over the exterior con-
denser coil faces on the sides of the unit to visually
screen and protect coils. (Factory-mounted)
w Louvered (Condensers) /Wire (Mechanicals)
– Louvered panels mounted over the exterior
condenser coil faces, and heavy gauge welded
wire mesh guards mounted around the bottom of
the unit. Visually screens and protects coils, and
