AC Tonnage Input
Cooling Output
42,000
BTU/hr
Thermal kW:
12.31 kW
Approx. Running Power:
4,200 W
Rec. Generator Size:
8.5 kW+
BTU/hr = 3.5 Tons × 12,000 = 42,000 BTU/hr
How to Convert Tons to BTU
Multiply the number of refrigeration tons by 12,000 to get the total cooling capacity in BTU per hour.
