Amazon Cooler Collar

The Amazon Cooler Collar is a thermoelectric based air conditioner that simply clips to the back or front of an Amazon 19-inch rackmount transit case. It instantly circulates cool air through the interior and maintains a constant, desired temperature.

The Cooler Collar utilizes a solid-state 200 to 3,000 BTU/HR thermoelectric cooler. The internal cool air does not mix with the external ambient air. It’s maintenance-free and easy to install.

The Amazon Cooler Collar is a convenient air conditioning solution for deployed electronics and communications equipment.



  • The Cooler Collar is supplied with two lids for protection during transportation and storage.
  • Maintenance-free and long-life operation.
  • Units can be clipped to the front and rear of an Amazon Rack for additional cooling.
  • Cool air only circulates within the rack protecting delicate electronics from dusty and contaminated environments.
  • Instantly detachable. A unit can be removed to access the equipment or transferred quickly to another Amazon Rack.
  • The Cooler Collar does not consume space within the rack.
