Horizon Series Top-Mount Air Conditioners

Horizontal, Top-Mounted Air Conditioners for Limited-Space Enclosures

Kooltronic's Horizon Series top-mounted air conditioners provide a full range of cooling capacities where space or other constraints prevent mounting onto an enclosure's panel or internal rack. This versatile line of air conditioning units offers five series of models, from 2,500 to 12,000 BTU/H, in five sizes. They feature specially designed, heavy-duty centrifugal blowers or fans that force cool air throughout the enclosure. The Horizon Series offers numerous models to meet broad range of requirements — from the low profile Horizontal Super-Mini or Compact models for low to moderate-demand cooling applications in smaller enclosures to the 5,000 BTU/H Compact Plus for more demanding applications, or larger/denser enclosures. The largest model in the Horizon Series is available in a capacity range covering applications requiring cooling to 12,000 BTU/H.

Kooltronic also offers custom-designed cooling solutions for unique requirements.
