P. Power Factor Correction Capacitors: Provided to correct unit compressor factors to a
0.90-0.95.
Q. Condenser Coil Environmental Protection:
1. Pre-Coated: Epoxy coated aluminum n stock to guard from corrosive agents and
insulate against galvanic potential. For mild seashore or industrial locations.
2. Copper Fin: Provide copper ns in lieu of aluminum.
3. Post-Coated Dipped: Dipped-cured coating on condenser coils for seashore and
other corrosive applications (with the exception of strong alkalis, oxidizers, and wet
bromine, chlorine and uorine in concentrations greater than 100ppm).
R. Protective Chiller Panels (Factory or Field Mounted)
1. Louvered Panels (condenser coils only): Painted steel as per remainder of unit cabi-
net, over external condenser coil faces.
2. Wire Panels (full unit): Heavy gauge, welded wire-mesh, PVC-coated to resist cor-
rosion, to protect condenser coils from incidental damage and restrict unauthorized
access to internal components.
3. Louvered Panels (full unit): Painted steel as per remainder of unit cabinet, to protect
condenser coils from incidental damage, visually screen internal components, and
prevent unauthorized access to internal components.
4. Louvered/Wire Panels: Louvered steel panels on external condenser coil faces,
painted as per remainder of unit cabinet. Heavy gauge, welded wire-mesh, coated
to resist corrosion, around base of machine to restrict unauthorized access.
S. Flow Switch (Field-mounted): Vapor proof SPDT, NEMA 4X switch ( ___150 PSIG or
___300 PSIG), -20°F to 250°F.
T. Differential Pressure Switch: Alternative to an above mentioned ow switch. Pretemp-
co model DPS300A-P40PF-82582-5 (300 psi max. working pressure) SPDT 5 amp
125/250VAC switch, Range 3-45 PSIG (0.2-3 barg), deadband 0.5 - 0.8 psi, with 1/4”
NPTE Pressure Connections.
U. Evaporator options:
1. Provide 1½" cooler insulation in lieu of standard ¾".
2. Provide DX Cooler with 300 PSIG water-side design working pressure in lieu of
standard 150 PSIG.
3. Provide Raised Face Flanges for eld installation on cooler nozzles and eld piping:
a. 150 PSIG, welded Flanges.
b. 300 PSIG, welded Flanges.
V. Service Isolation valves: Service suction and discharge (ball type) isolation valves are
added to unit per system. This option also includes a system high pressure relief valve
in compliance with ASHRAE 15. (Factory-mounted.)
