Underceiling Duct-Free Split Systems – Commercial

For quiet comfort, our underceiling duct free systems provide the right solution.

Mounted snugly against the ceiling, these products fit seamlessly into nearly any room to enhance the comfort. Comfort levels can be easily and precisely controlled using the optional wired controller or optional infrared remote controller (on Toshiba-Carrier models). When faced with a unique load (need for cooling in heating season) or a need for auxiliary cooling (for example, the addition of a conference room), commercial underceiling systems provide an ideal solution.

Carrier brand underceiling systems are the only in the industry that offer 4 and 5 ton models. With refrigerant piping of 165-245 feet, you gain additional flexibility to place the outdoor unit farther from the room being heated/cooled. Especially in fixed load applications (cooling equipment), Carrier branded commercial fixed speed underceiling systems can cool your equipment even when the outdoor temperature gets down to -20 deg F. At 3, 4 and 5-ton capacity, you have industry exclusive 3-phase electric capability in 230V and 460V Carrier branded commercial underceiling systems.

Toshiba-Carrier underceiling systems have the highest SEER efficiency rating in the industry.

With all these features for your commercial applications, Carrier and Toshiba-Carrier commercial cassette systems offer you the right product for the right application.
