HelioJET® Cost Comparison
The following figures show an example of a cost comparison for operation of a HelioJET®
C60 Central Cleaning System vs. a 50 HP Kobe Pump/Steam Sparger System
Electrical Cost Comparison:
C60 Central Cleaning System 
Kobe / Sparger System 
System only runs when cleaning occurs 
System runs continuously 
7.5 HP x .746 KW x 1 hr = 5.60 / KWH 
50 HP x .746 KW x 1 hr = 37.30 / KWH 
5.60 KWH x $.08 / KWH = .448 / HR 
37.30 KWH x $.08 / KWH = 2.98 / HR 
(.448 x 8 Hours Actual Running Time) 
(2.98 x 24 Hours Actual Use Time) 
Electricity Cost per Day: $3.58 
Electrical Cost Per Day: $71.52 
Electrical Cost Per Year: $1,306.70 
Electrical Cost Per Year: $26,104.80 
Steam Cost Comparison:
C60 Central Cleaning System 
Kobe / Sparger System 
Creates hot water on demand 
Constantly maintains hot water 
Discharge Water Temp = 160° F 
Discharge Water Temp = 160° F 
Temperature Rise = 100° F 
Temperature Rise = 100° F 
Daily Water Usage = 8,000 Gallons 
Daily Water Usage = 8,000 Gallons 
Steam Cost = $7.00 / 1000 lbs. 
Steam Cost = $7.00 / 1000 lbs. 
(100° F / 138) x 8,000 = 5,797 lbs. Per day 
(100° F / 138) x 8,000 = 5,797 lbs. Per day 

Estimated increase in steam consumption due to radiation and evaporative losses 

(5,797 x 1.4) = 8,115.80 lbs. per day 
Steam Consumption = 5,797 lbs. per day 
Steam Consumption = 8,115 lbs. per day 
(5,797 / 1000) x $7.00 = $40.58 
(8115 / 1000) x $7.00 = $56.81 
Steam Cost Per Day: $40.58 
Steam Cost Per Day: $56.81

Steam:  $40.58 / Day $14,811.70 / Year 
Steam:  $56.81 / Day $20,735.65 / Year 
$44.16 / Day  $16,118.40 / Year 
$128.33 / Day  $46,840.45 / Year 
Total Savings: $84.17 / Day  $30,722.05 / Year
Please Note: Due to the fact that the HelioPAC™ contains no moving parts, no savings due to
reduced maintenance costs could be calculated.
