Product Description
The following options provide added protection:
Black fin condenser coils – Condenser coils constructed
using black epoxy coated Aluminum fin stock for corro-
sion resistance comparable to copper fin coils in typical
seashore locations.
Copper fin condenser coils – Coils constructed with
corrosion resistant copper fins. Not recommended in
areas where units may be exposed to acid rain.
Phenolic coated condenser coils – Completed condens-
er coil assemblies are covered with a cured Phenolic
coating. Probably the most suitable selection for sea-
shore locations where salt spray may come into contact
with the fins, and other corrosive applications except:
strong alkalis, oxidizers, and wet bromine, chlorine, and
fluorine in concentrations greater than 100 PPM.
DX COOLER OPTIONS
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)
1-1/2" (38 mm) Insulation – Double thickness insula-
tion provided for enhanced efficiency.
Flange Accessory – Consists of raised face flanges
to convert grooved water nozzles to flanged cooler
connections. Includes companion flanges for field-
mounting.
Remote DX Cooler – Includes the main condensing unit
less the cooler, refrigerant and liquid line devices. The
insulated cooler and field accessory kits per refrigerant
circuit are supplied separately. The condensing unit is
shipped with an R-22 holding charge and the cooler is
shipped with a nitrogen holding charge.
Flow Switch Accessory – Johnson Controls model
F61MG-1C Vapor-proof SPDT, NEMA 4X switch, 150
PSIG (10 bar) DWP, -20°F to 250°F (-29°C to 121°C),
with 1" NPT (IPS) connection for upright mounting in
horizontal pipe. A flow switch must be field installed
with each unit.
Star-Delta Compressor Motor Starter – Provides
approximately 65% reduced inrush current compared
to across-the-line start (Factory-mounted).

UNIT ENCLOSURES
Wire enclosure – Heavy gauge welded wire mesh
guards mounted on the exterior of the unit (Factory- or
field-mounted).
Louvered panels and wired guards – Louvered panels
mounted over the exterior condenser coil faces, and
heavy gauge welded wire mesh guards mounted around
the bottom of the unit (Factory- or field-mounted).
Louvered panels (condenser coils only) – Louvered
panels are mounted over the exterior condenser coil faces
on the sides of the unit to visually screen and protect the
coils (Factory- or field-mounted).
Louvered panels (full unit) enclosure – Louvered
panels over condenser coils and around the bottom of
the unit (Factory- or field-mounted).
FANS
High static fans: Fans and motors suitable for High
External Static conditions to 100 Pa.
SOUND REDUCTION OPTIONS
Low speed fans – Reduced RPM fan motors and alter-
native fan selection for low noise applications.
Compressor sound enclosures – Acoustically
treated metal compressor enclosures. Includes a com-
pressor mounted temperature transducer to prevent
overheating.
VIBRATION ISOLATION
Neoprene pad isolation – Recommended for normal
installations. (Field-mounted)
1" (25 mm) spring isolators – Level adjustable, spring
and cage type isolators for mounting under the unit base
rails (Field-mounted).
2" (51 mm) seismic spring isolators – Restrained
Spring-Flex Mountings incorporate welded steel hous-
ing with vertical and horizontal limit stops. Housings
designed to withstand a minimum 1.0 g accelerated force
in all directions to 2" (51 mm). Level adjustable, deflec-
tion may vary slightly by application. (Field- mounted).
