nolic coating. Probably the most suitable selection for
seashore locations where salt spray may come into con-
tact with the fins, and other corrosive applications ex-
cept: strong alkalis, oxidizers, and wet bromine, chlo-
rine, and fluorine in concentrations greater than 100
PPM.
DX COOLER OPTIONS:
21 bar (300 PSIG) Waterside Design Working
Pressure – The DX cooler waterside is designed and
constructed for 21 bar (300 PSIG) working pressure.
(Factory Mounted)
38 mm (1-1/2") 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 refrig-
erant 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, 10
bar (150 PSIG) DWP, -29°C to 121°C (-20°F to 250°F),
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 pan-
els 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 pro-
tect 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)
25 mm (1") spring isolators – Level adjustable, spring
and cage type isolators for mounting under the unit base
rails (Field mounted).
51 mm (2") 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,
deflection may vary slightly by application. (Field
mounted).
