Calculating Electricity Use

Hello, Everyone!

I would like to ask if you have a formula to calculate the electricity used at various pressures and temperatures by a 48 litre (12.7 gallon) extraction unit with a maximum working pressure of 500 bar (7251.89 psi) and a maximum working temperature of 75 C (23.8 F).
I know that the question is very general and can vary significantly between machines, but I am looking for a rough estimate.

Thank you very much in advance!


  • I think, and the community will correct me :), to calculate the electricity used you need to use your electrical utilities as the measure (i.e. pump, chiller, etc.. They, likely, are what regulate the pressure/temperatures you seek.

    So, if you know the wattage you'd multiply that by the use time:
    1) 125 watts x 3 hours a day = 375 watts per day.
    2) 375 watt-hours per day / 1000 =0.375 kWh per day
    3) 375 watt-hours per day X 30 days = 11.25 kWh per month

  • Thank you so much! We actually calculated it in a super complicated way and got the same results. :D
    Best of luck to you!
