YORK INTERNATIONAL 2
Introduction
The eco 2 packaged rooftop – Designed to meet the de-
mands of the market for today and tomorrow.
Better Economy...
Reduce Energy Consumption
• High-efficiency eco 2 rooftop units are optimized for
both R-22 and HFC-407C refrigerant, and are the
first environmentally responsible rooftop units that
meet the ASHRAE 90.1-2001 efficiency standards.
• Multiple steps of capacity-control offer superior off-
design energy performance, while maintaining bet-
ter control of occupant comfort.
• The OptiLogic TM Control Center ensures that no
more than the proper amount of ventilation air is
utilized, avoiding the energy cost of conditioning
excess air.

Air Quality Features for the Indoor Environment
• A double-sloped stainless steel design ensures that
all condensate is voided from the drain pan. The drain
pan is also visible and accessible for the periodic in-
spection and cleaning required by IAQ standards.
• Double-wall construction of the roof, floor, doors,
and walls prevents insulation fiber from entering
the supply air. The inner liner also facilitates peri-
odic cleaning of the unit to prevent harmful build-
up of bacteria or contaminants.
• The OptiLogic TM Control Center uses microproces-
sor logic to analyze and optimize ventilation decisions.
• A true airflow-measurement station can be supplied,
to ensure the proper ventilation at all supply-air
volumes.
• An available sensor can monitor the CO
2
level within
the building and adjust the ventilation rate on de-
mand, to maintain the air quality at a healthy level.
HFC-407C Refrigerant
for the Global Environment
The OptiLogic TM Control Center uses microprocessor logic to opti-
mize operation of the eco 2 rooftop unit.
