Efficiency Requirements

Introduction

The eco2 packaged rooftop Designed to meet the demands of the market for today and tomorrow.

Better Economy...

Reduce Energy Consumption

High-efficiency eco2 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 offdesign energy performance, while maintaining better control of occupant comfort.

The OptiLogicTM 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 inspection 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 periodic cleaning of the unit to prevent harmful buildup of bacteria or contaminants.

The OptiLogicTM Control Center uses microprocessor logic to analyze and optimize ventilation decisions.

A true airflow-measurement station can be supplied,

to ensure the proper ventilation at all supply-air

An available sensor can monitor the CO2 level within the building and adjust the ventilation rate on demand, to maintain the air quality at a healthy level.

The OptiLogic TM Control Center uses microprocessor logic to optimize operation of the eco2 rooftop unit.
