FEATURES/BENEFITS

Ecological and Economical Design

•First packaged RTU with 407C optimized design

•Cooling and Heating – Superior operating perfor- mance provides lower operating costs. Smaller steps of cooling capacity provide tighter control of building environment and occupant comfort while optimizing energy efficiency.

•Indoor Air Quality (IAQ) – Outside air economiz- ers provide energy savings in free cooling mode, and can provide a healthier and more comfortable building environment by introducing fresh outside air into the building as needed. Indoor Air Quality (IAQ) requirements for building ventilation and comfort are controlled through the microprocessor control panel. Optional air flow measurement provides an accu- rate means of tracking air quality and alerting the occupants or building owner to unhealthy situations.

•High-Efficiency Motors – High-efficiency motors are available for optimum energy efficiency. All motors used on the eco2 packaged rooftop air conditioner meet U.S. EPACT 1992 minimum requirements.

in two directions conforming to ASHRAE 62n, this drain pan swiftly minimizes any condensate within the unit. Best of all, the drain pan is accessible for periodic cleaning required by IAQ standards.

•Smart ventilation – YORK maintains the leader- ship role in IAQ products with adaptive ventilation control. The OptiLogicTM controls provide continu- ous monitoring of air quality and take action by open- ing the outside air dampers, bringing in the right amount of fresh air before air impurities reach un- comfortable or even dangerous levels.

•Air flow measurement – Precise measurement of ventilation air flow is possible using an air flow measurement station which can be installed in the economizer section. Proper ventilation air flow is required to ensure sufficient fresh air is in the build- ing. A myriad of air flow measurement options are available from minimum air flow to high-accuracy full air flow capabilities. The complete system is designed as an integrated component of the OptiLogicTM control system to ensure optimum sys- tem performance.

Indoor Air Quality (IAQ)

•Double-sloped stainless steel drain pan – This double-sloped inclined stainless steel drain pan fa- cilitates removal of evaporator condensate. Sloped

•Double-wall construction – Rigid double-wall construction throughout provides ease of clean- ing and protects against insulation fiber entrain- ment in the breathable air. Double-wall construc- tion also helps improve the acoustical character- istics of the air handling unit.
