YORK Air-Cooled Scroll Chillers provide chilled water for all air conditioning applications
using central station air handling or terminal units. They are completely self-contained and
are designed for outdoor (roof or ground level) installation. Each unit includes hermetic
scroll compressors, a liquid cooler, air cooled condenser, a charge of refrigerant R-410A,
and a weather resistant microprocessor control center, all mounted on a rugged, formed-
steel base.
GENERAL
The 15 - 65 Ton (53 - 218 kW) YCAL models are shipped complete from the factory ready
for installation and use.
The unit is pressure-tested, evacuated, and fully charged with R-410A and includes an
initial oil charge. After assembly, a complete operational test is performed with water flow-
ing through the cooler to assure that the refrigeration circuit operates correctly.
The unit structure is heavy-gauge, galvanized steel. The steel is coated with baked-on
powder paint, which, when subjected to ASTM B117 1000 hour, salt spray testing, yields
a minimum ASTM 1654 rating of “6”. Corrosion resistant wire mesh panels are added
to protect the condenser coil from incidental damage and restrict unauthorized access
to internal components. Unit also includes service isolation valves as standard. Units
are designed in accordance with NFPA 70 (National Electric Code), ASHRAE/ANSI 15
Safety code for mechanical refrigeration, ASME, Listed and labeled with Intertek Testing
Services (ETL) and rated in accordance with the latest version of ARI Standard 550/590.
COMPRESSORS
The chiller has suction-gas cooled, hermetic, scroll compressors. The compressors incor-
porate a scroll design that is compliant in both the axial and radial direction. All rotating
parts are statically and dynamically balanced. A large internal volume and oil reservoir
provides greater liquid tolerance. Compressor crankcase heaters are also included for
extra protection against liquid migration.
COOLER
Brazed plate heat exchangers are UL (Underwriters Laboratories) listed. Installing con-
tractor must include accommodations in the chilled water piping to allow proper drainage
and venting of the heat exchanger. Water inlet and outlet connections are grooved for
compatibility with factory supplied ANSI/AWWA C-606 connections.
The cooler is equipped with a heater controlled by a separate thermostat. The heater
provides freeze protection for the cooler down to -20°F (-29°C) ambient. The cooler is
covered with 3/4” (19mm) flexible, closed-cell, foam insulation (K≈0.25).
A 40 mesh strainer (0.5 and 1.5 mm) is recommended upstream of the heat exchanger to
prevent clogging.

Introduction (Cont'd)
CONDENSER
Coils – Fin and tube condenser coils of seamless, internally-enhanced, high-condensing-
coefficient, corrosion resistant copper tubes are arranged in staggered rows, mechani-
cally expanded into aluminum fins. Integral subcooling is included. The design working
pressure of the coil is 650 PSIG (45 barg).
Low Sound Fans – The condenser fans are composed of corrosion resistant aluminum
hub and composite blades molded into a low noise airfoil section. They are designed for
maximum efficiency and are statically and dynamically balanced for vibration-free opera-
tion. They are directly driven, and positioned for vertical air discharge. The fan guards are
constructed of heavy-gauge, rust-resistant, PVC (polyvinyl chloride)-coated steel wire.
Motors – The fan motors are Totally Enclosed Air-Over, squirrel-cage type, current pro-
tected. They feature ball bearings that are double-sealed and permanently lubricated.
AHRI CERTIFICATION PROGRAM
YORK YCAL chillers have been tested and certified by Air-Conditioning, Heating and Re-
frigeration Institute (AHRI) in accordance with the latest edition of AHRI Standard 550/590
(I-P). Under this Certification Program, chillers are regularly tested in strict compliance
with this Standard. This provides an independent, third-party verification of chiller perfor-
mance. Refer to the AHRI site at: http://www.ahrinet.org/ for complete Program Scope,
Inclusions, and Exclusions as some options listed herein fall outside the scope of the
AHRI certification program. For verification of certification, go to the AHRI Directory at
www.ahridirectory.org.
Rated in accordance with the latest
issuance of AHRI Standard 550/590
and 551/591.

- 0.005 barg), with 1/4” NPTE Pressure Connections.
CONDENSER AND CABINET OPTIONS
Condenser coil protection against corrosive environments is available by choosing any
of the following options. For additional application recommendations, contact your local
Johnson Controls office.
Pre-Coated Fin Condenser Coils – The unit's coils are constructed with epoxy coated
aluminum fins. This can provide corrosion resistance comparable to copper-fin coils in
typical seashore locations. Either these or the post-coated coils (below), are recommend-
ed for units being installed at the seashore or where salt spray may hit the unit.
Post-Coated Dipped Condenser Coils – The unit's coils are constructed with dipped-
cured condenser coils. This is the choice for corrosive applications (with the exception of
strong alkalies, oxidizers and wet bromine, chlorine and fluorine in concentrations greater
than 100 ppm).

Copper Fin Condenser Coils – The unit coils are constructed with copper fins. (This is
not recommended for units in areas where they may be exposed to acid rain.)
Enclosure Panels (Unit) – Tamperproof enclosure panels prevent unauthorized access
to units. Enclosure panels can provide an aesthetically pleasing alternative to expensive
fencing.
Louvered Panels (Full Unit) – Louvered panels surround the front, back, and sides of the
unit. They prevent unauthorized access and visually screen unit components. Unrestricted
air flow is permitted through generously sized louvered openings. This option is applicable
for any outdoor design ambient temperature up to 115°F (46°C). Recommended for use
with the Low Ambient kit where wind gusts may exceed five mph (eight kph).
Sound Attenuation – One or both of the following sound attenuation options are recom-
mended for residential or other similar sound-sensitive locations.
Compressor Acoustic Sound Blanket – Each compressor is individually enclosed by
an acoustic sound blanket. The sound blankets are made with one layer of acoustical
absorbent textile fiber of 5/8” (15mm) thickness; one layer of anti-vibrating heavy mate-
rial thickness of 1/8” (3mm). Both are closed by two sheets of welded PVC, reinforced for
temperature and UV resistance.
Ultra Quiet Fans – Lower RPM, eight-pole fan motors are used with steeper-pitch fans.
Vibration Isolators – Level adjusting, spring type 1” (25.4mm) or 2" deflection or neo-
prene pad isolators for mounting under unit base rails. (Field-mounted.)

Selection Data
GUIDE TO SELECTION
Capacity ratings for the YCAL Packaged Air-Cooled Liquid Chillers, shown on pages 20
through 37 cover the majority of design applications for these units. For unusual appli-
cations or uses beyond the scope of this catalog, please consult your nearest Johnson
Controls Office or sales representative.
SELECTION RULES
1. Ratings – Ratings may be interpolated, but must not be extrapolated. The Ratings
on page 20 and the Design Parameters on page 17 indicate the limits of ap-
plication for these chillers.
2. Cooler Water – Ratings are based upon 2.4 GPM per ton which is equal to a 10°F
chilled water range and a 0.0001 fouling factor for the cooler at sea level. Tables on
pages 20 through 37 give capacity, compressor kW required, cooler GPM and unit
EER.
3. Condenser – Ratings are given in terms of air on condenser in degrees Fahrenheit.
4. Copper Fin Condenser Ratings – Since the thermal conductivity of copper is
slightly higher than aluminum, apply the following corrections to the standard rat-
ings. Tons x 0.97 and compressor kW x 0.99.
5. Performance Data Correction Factors – Ratings are based on 0.0001 cooler foul-
ing factor, 10°F chilled water range and at sea level. For operation at different condi-
tions, apply the appropriate correction factor from the following table.
