Protect your assembly lines, CNC machines, food processing, injection molding, manufacturing plants, process cooling, warehouses and workers from the hottest environments with industrial portable air conditioning solutions. Bring cool-refrigerated air to production lines; reduce the risk of heat exhaustion to your employees; eliminate warping and condensation due to excess heat and humidity in your industrial environment; and cool your heat-generating equipment.

Data Centers & Telecom Applications

Protect your critical equipment by supplying supplemental or instant emergency back-up cooling.  Adding more servers to your existing data center will increase your heat load requiring more cooling.  Our compact portable computer cooling units conveniently roll in to tight spaces, or mount directly into your server rack providing a quick spot cooling solution.  With programmable controls these units can keep your equipment cool after business hours and during weekends.


As more heat generating equipment is being used  today, portable spot coolers for uses in hospitals, imaging centers, laboratories, MRI rooms, outpatient facilities, exam rooms and x-ray equipment are a wonderful solution to keep these facilities running smoothly.   Whether for temporary use for overcrowded patient areas, to prevent heat generating laboratory equipment from shutting down, for construction areas where the main A/C is temporarily offline, or supplemental cooling of MRI and other imaging equipment.

Portable spot coolers may be used for a variety of purposes in these industries, including the following:

  • Temporarily cooling overcrowded patient areas
  • Preventing heat generating laboratory equipment from shutting down
  • Cooling construction areas where the main AC is temporarily offline
  • Providing supplemental cooling of MRI and other imaging equipment
