Metal Finishing Chillers

To determine the size of chiller you’ll need for your metal finishing operation, follow this formula:

  1. Obtain output of rectifier (Amp & Volts)
  2. Obtain total BTU's Total BTU's = Amps x Volts x 3.414
  3. Calculate tons of cooling capacity Tons = BTU ÷ 12,000
  4. Size chiller by rounding up to the closest standard unit size

For example:

  1. Rectifier output Is 1,000 Amps & 24 Volts
  2. Total BTU's = 1,000 x 24 Volts x 3.414 = 81,936
  3. Tons= 81,936 ÷ 12,000 = 6.83 tons
  4. This application will require a 7.5-Ton unit

Plug in the following two inputs into the calculator below to get the estimated chiller size you need for your application.

  • Rectifier Amperage Output
  • Rectifier Voltage Output
