INTRODUCTION / TECHNICAL DATA 

HOW IT WORKS

 

The Whynter compact CFC-free, lead-free, and energy efficient 12,000 BTU portable air condition-er, helps you stay 
cool while working with better environmental standards and reducing energy con-sumption. 

This high output portable air conditioner, specially designed to be mobile, can be easily setup in almost any indoor 
location and is most commonly used in data closets / server rooms, bedrooms, classrooms and garages / 
workshops. 

This Whynter ARC-126MD portable air conditioner features an ECO-FRIENDLY CFC-free GREEN R-410A 
refrigerant and lead-free RoHS compliant components.

Operationally, a dual hose portable air conditioner has two main advantages over a single hose unit. A dual hose 
portable air conditioner 

can help

 cool a room faster and will help minimize 

negative air

 

pressure situation in the

room. If the outside temperature is much higher or more humid than the room, the intake hose can be detached and 
the unit will function as a single hose unit.
