Includes a 20% safety factor to compensate for high losses and/or low power voltage.

Equation to calculate kilowatts:

KW = Kilograms x Temperature Rise (°C)
              5040 x Heat-up Time (hrs.)

 

 

 

| KW hours heat Steel | KW hours heat Water | KW hours heat Air | KW hours heat Oil | Watt Density Chat |

| Appliances | Water Heater | Component Heater | Immersion Heater | Circulation Heaters |
| Process Air Heaters | Canteen Equipments | Control Panel |
