Replacing a single home made drilled pipe can significantly reduce energy costs It did for A food processing plant who just eliminated 30 of their homemade blowoffs saved $13,665 per year with each pipe replaced.
Here's the math!
-
Existing blowoff is approx. 500mm long pipe with 54 x 2.38mm diameter holes operating at 80 PSIG (5.5 BAR). Air consumption from chart is 9.4 SCFM per hole. Total air consumption is
54 x 9.4 = 507.6 SCFM -
Use 24" (610mm) Super Air Knife with standard .002" gap and 80 PSIG supply. Air consumption from chart is 2.9 per inch. Total air consumption is 24 x 2.9 = 69.6 SCFM
-
Compressed air saved = 507.6 SCFM - 69.6 SCFM = 438 SCFM
-
Most large plants know their air cost. If you don't know your actual cost, a reasonable average to use is $0.25 per 1000 SCF
-
Dollars saved per hour = SCFM saved x 60 minutes x cost/1000 SCF = 438 x 60 x $0.25/1000
= $6.57 per hour
= $262.80 per 40 hour week
= $13,665.60 per year savings*
*Based on national average electricity cost of 8.3 cents per kWh. Annual cost reflects 40 hours per week, 52 weeks per year.
A 24" (610mm) Stainless Steel Super Air Knife would save enough in compressed air costs to
pay for itself in less than seven (7) weeks!
