How to Determine BTU Per Hour

To determine BTUs per hour for air conditioning requirements, multiply the total watts of the power supply by 3.413.


A FRED system's 1100W power supply (pre 2019) would generate 3754 BTU/Hour.

A FRED system's 1200W power supply (2019+) would generate 4095 BTU/Hour.

A FREDC Data Center utilizes a UPS with a maximum output of 2700W. This results in a maximum heat output of 9215 BTU/Hour.
