The metal surface finishing includes electroplating, anodizing, and coating. The metal finishing processes typically produce significant quantities of thermal energy which can adversely affect the quality of finished products if not properly dissipated. Temperature control is an important part of the surface finishing process. Keeping the rectifier cool and the tank(s) at a steady temperature is imperative to high-quality parts. Focus on the eager needs of the surface finishing factory, Kingfit designed high-quality corrosion-resistant surface finishing chillers based on your design requirements for thermal load, unit size constraints, special voltages, and special operating conditions (low temperature, high ambient, etc). So as to solve the problems in finishing processing.

Including Zinc Plating, Chrome Plating, Nickel Plating, Gold Plating, Silver Plating, Aluminum Anodizing, Cookware Hard Anodizing, etc.

To determine the size of chiller you’ll need for your metal finishing operation, follow this formula:
Obtain output of rectifier (Amp & Volts)

1. Obtain total BTU’s Total BTU’s = Amps x Volts x 3.414
2. Calculate tons of cooling capacity Tons = BTU ÷ 12,000
3. 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
the size you need for your application.

• Rectifier Amperage Output
• Rectifier Voltage Output
