All 48/50 E-Series models feature dual independent refrigeration circuits and semi-hermetic compressors with service valves. If one circuit is shut down, the other will continue to provide reliable cooling. |
The 48/50 E-Series meets or exceeds most standard feature requirements as well, including EERs to 10.4, compliance with ASHRAE 62-89, single-point power entry, pre-painted galvanized steel cabinet, and both constant air volume and variable air volume (VAV) models. All supported by the strongest distributor, dealer and service network in the industry.
Features | Benefits |
Dedicated down discharge and supply (EJ/EK) and side discharge and supply (EW/EY) models |
Flexibility for all types of applications |
48/50 EK/EY variable air volume models with variable frequency drives and up to six steps of unloading |
Optimum comfort in the most energy-efficient manner |
Dual independent refrigeration circuits and semi-hermetic compressors with service valves |
Application is never without reliable, redundant cooling |
Oversize blowers with motor/drive options that are up to 3.5" static capable |
Great for retrofit/replacement applications where additional cooling is required, and situations with long and/or tightly-sized ductwork |
Gear-drive low-leak economizers |
Reliable, precise control of ventilation air |
Optional barometric relief on constant volume and variable air volume models |
Low-cost over-pressurization relief for buildings with limited return ductwork |
Optional 100% power exhaust, using centrifugal blowers, on all constant volume and variable air volume models |
Best over-pressurization relief for buildings with high-static, extended length ductwork |
48/50 EJ/EW models can be controlled with an electromechanical thermostat |
Simplest, lowest cost unit control |
Direct Digital Controls that are fully expandable with plug-in modules and CCN-ready |
Control functions can be tailored to meet job requirements at lowest cost. Equipment performance can be fine-tuned to manage energy use and minimize operating cost |
Antimicrobial insulation, sloped condensate pans and easy-access evaporator facilitate equipment cleanliness |
