FORM 100.50-EG5 (108)

Double Wall Construction – Double-wall construction 
is the standard construction of the Eco

2

 and incorporates 

powder coated pre-fabricated outer panels and corner 
post for maximum exterior surface protection.

Factory Shrink-wrap – Eco

2

 rooftop units are shipped 

from the factory with factory-fresh shrink-wrap packag-
ing. No longer does the contractor need to worry about 
dirt and debris clogging up condenser coils or moisture 
leaking into the air handler on the units way to the job 
site or rigging yard.

Copper Fins – For more extreme climates that aggres-
sively can attack aluminum, copper tube evaporator coils 
with copper fi ns are available. (This is not recommended 
for units in areas where they may be exposed to acid 
rain or environments where ammonia is present)

Scroll Compressors – Reliable, effi cient, trouble-free 
operation is the true measure of a packaged rooftop’s 
value. That’s why YORK Eco

2

  Packaged Rooftop 

Air Conditioners use established scroll compressor 
technology to deliver dependable, economical per-
formance in a wide range of applications. With the 
Eco

2

 Packaged Rooftop, you get the latest generation 

of compressor enhancements added to the scroll’s 
inherent strengths. The simplicity of a hermetic scroll 
compressor allows the use of fewer moving parts to 
minimize breakdown. 

Multiple Compressor Staging – Through the use of the 
scroll compressor, the Eco

2

 has the ability to stage its 

cooling by enabling and disabling multiple single stage 
compressors on multiple circuits. These compressors 
are manifolded together in pairs on a single refrigera-
tion circuit. 

Compressor Circuiting – the Eco

2

 is designed so that 

only 2 scroll compressors are in tandem within one refrig-
eration circuit. This means more reliable compressors, 
and less equipment down time. With multiple circuits, if 
a compressor should ever fail on one circuit, the other 
circuit will remain operational to work to maintain occu-
pied loads. The Eco

2

 system has 2 circuits in a unit.

Condenser Fan Motors – The condenser fan motors 
used on the Eco

2

 unit are Totally Enclosed Air Over 

(TEAO) to provide maximum durability through any 
season.

Hot Gas Bypass – This options permits continuous, 
stable operation at capacities below the minimum step 
of unloading by introducing an artifi cial load on the 
evaporator. For models YPAL050-061, it is used on the 
lead circuit and standard on VAV units.

Replaceable Core Liquid Line Driers – Liquid line 
driers are standard on the Eco

2

 rooftop unit. An option 

is provided for replaceable core driers. 

Copper Fins – For more extreme climates that aggres-
sively can attack aluminum, copper tube condenser coils 
with copper fi ns are available. (This is not recommended 
for units in areas where they may be exposed to acid 
rain or environments where ammonia is present)

Pre-Coated Fins – An epoxy-coated aluminum fi n stock 
to guard from corrosive agents and insulate against 
galvanic potential. Recommended for mild seashore or 
industrial locations.

Post-Coated Fins – Technicoat coil-coating process 
used on condenser coils for seashore and other cor-
rosive applications (with the exception of strong alkalis, 
oxidizers, wet bromide, chlorine and fl uorine in concen-
trations greater than 100ppm).

Compressor Sound Blankets – Optional compressor 
acoustic sound blankets are available for sound sensi-
tive applications.

Partial perimeter roof curbs – This option includes a 
knock-down 14” high roof curb for use with wood nailer 
(by others). Roof curb supports the air handling section 
with a separate support under the condenser end.

Double-Wall Access Doors - Full-sized access doors 
provide easy access into the unit for routine maintenance 
and inspection. Solid wall liners encase insulation and 
prevent damage and erosion into the airstream.

Industry-leading, 1,000-hour, salt-spray rating, per 
ASTM B117, keeps unit in superior condition.
