Dual Discharge Unit Coolers
Low-profile dual discharge unit coolers for packing rooms, processing halls and cold rooms where people work. Air leaves both sides, so the room holds an even temperature without ductwork.
Best for Packing rooms, processing halls and cold work areas where people need even, low-velocity air under a low ceiling.

Questions buyers ask
What is a dual discharge unit cooler?
A low-profile evaporator that blows air out of both sides instead of one. Air speed at any point stays lower, so rooms where people work stay even without ductwork.
How many models are there?
148 published models with 14, 18 or 22 in EC fans on HFC, pumped HFC, CO2 and ammonia, each rated at high and low fan speed.
Where does a dual discharge unit fit better than a standard unit cooler?
In rooms with low ceilings, or where a single throw would leave one end warm and blow hard on the people at the other.
