The Zoneline 2500, 3500 and 5500 Series have incorporated changes suggested by customers and enhancements by GE’s Technology team:

-Auto Heat/Auto Cool settings to reduce operating sound level while increasing occupant comfort

-Ability to connect to wall thermostat or Central Desk Control without additional interface module

-7-step temperature limiting with separately selectable heating and cooling limits

-Transfer Fan interface - enables a fan mounted in the wall to operate in conjunction with the unit fan (fan, wiring and relay are field supplied)

-“Smart Fan” fan cycle/fan continuous operation to increase room occupant comfort

-Easier installation of chassis in existing wall cases

See the “Features and Benefits” section for in depth explanation of these changes and the industry leading features of the GE Zoneline retained from the previous series.

The Dry Air 25 system, a heat pipe, is a hermetically sealed heat transfer surface installed in a “saddlebag” configuration around the indoor (evaporator) coil of the Zoneline. This coil arrangement will transfer heat from the front coil of the saddlebag to the rear coil without power consumption. This assembly uses R-22 as the refrigerant and is not connected to the regular Zoneline refrigerant circuit.

As warm humid air is pulled through the pre-cool (front) section of the heat pipe, the heat removed from the air is absorbed by the refrigerant, causing the refrigerant to change to a gas and flow to the re-heat (rear) section of the heat pipe. The air leaving the pre-cool section of the heat pipe is cooler and at a higher relative humidity level than the room air. The pre-cooled air is further cooled as it passes through the evaporator; consequently, the relative humidity increases allowing the evaporator coil to remove more moisture.

When the cold air from the evaporator comes in contact with the re-heat section of the heat pipe, the heat that was removed by the pre-cool section is added back to the air and the refrigerant in the heat pipe condenses and flows back to the indoor coil. The air discharged into the room by this process is much drier, creating a more comfortable room condition.

The Newest Innovation from GE...

The Dry Air 25 Models center around GE’s exclusive use of the patented Dinh® Dehumidifier Heat Pipe from Heat Pipe Technology, Inc. This innovative NASA spin-off technology enables Dry Air 25 to remove 25% more moisture from the air than other leading manufacturers’ packaged terminal air conditioners. This helps maintain room comfort at a higher room temperature, reducing operating costs.

The Dry Air 25 keeps a room cool and dry, and this is the most important benefit when it comes to the occupant of the room - hotel guests, apartment residents, students...

In a hot, humid climate, getting away from the humidity is just as important as the heat, and the Dry Air 25 is the perfect solution. The dehumidifi- cation of the Dry Air 25 has been verified by the same ARI test conditions that standard units are rated under. A list of customers using Dry Air 25 is available from GE.
