Dx Cooler Options; 300 Psig (21 Bar) Waterside Design Working; Pressure; 1-1/2" (38 Mm) Insulation - York YCAS Series Installation Operation & Maintenance

The following options provide added protection:
Black fin condenser coils – Condenser coils con-
structed using black epoxy-coated aluminum fin stock
for corrosion-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 con-
denser coil assemblies are covered with a cured phenolic
coating. Probably the most suitable selection for seashore
locations where salt spray may come into contact with
the fins, and other corrosive applications except: strong
alkalis, oxidizers, and wet bromine, chlorine, and fluo-
rine 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 insu-
lation 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, 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 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 al-
ternative 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)
