I've got trouble with those numbers....
8,000 racks per 4 week period = 2,000 racks per week, or 285 racks per day (assuming its a 7 day/week operation)
One d/w cycle is 120 seconds, or two minutes . 285 x 2 = 570, divided by 60 (minutes in an hour), gives me a figure of 9.5.
Or in kitchen-speak, the dishwasher is running 9 and a half hours per day non-stop, or every two- three minutes the whole day, and those numbers are based on a 7/24 operation.
The cost given for a new d/w is $3,500 which leads me to believe that this would be an under-counter model. No undercounter dishwasher can stand that kind of volume for sustained period of time like two or three years.
I'm currently paying $115.00 per 2 x 10 liter (or aprox 5 US gallons) case of detergent, and $175.00 per 2 x 10 ltr case of rinse aid.
Granted, my consumption is based on volume, but $392 for a month's worth of d/w chemicals would be very high. For a larger place with banquet facilities yeah, sure, but for a place with a single tank, under-counter model?  |
