Download Application Profile #2 - Manual Control Steam Tracing vs. Automatic Control Using US/A or TV/SC/A Valve

EXAMPLE:

A winterizing steam tracing system in a plant located in Philadelphia, PA consumes about 500 pounds per hour of steam.

This system was manually turned on when the danger of freezing temperatures approached (mid-September) and turned off in late Spring when the danger of freezing had passed (mid-April). Total operating hours are 5,088:

212 days x 24 hours = 5,088 hours in potential freeze season.

The plant’s steam cost is $ 8.00 / 1,000 pounds of steam. The operating cost of this system can be calculated as follows:

COST OF MANUALLY OPERATED SYSTEM:

500 pounds per hour x 5,088 hours x $ 8.00/thousand pounds = $20,352.00 per winter season.

COST OF AUTOMATICALLY OPERATED SYSTEM:

When using ThermOmegaTech® ambient sensing TV/SC-A or US/A valves, steam tracing will be turned off automatically whenever ambient temperatures rise above 45°F (other closing temperatures can also be specified). Based on U.S. Weather Bureau data for Philadelphia, steam will be on for only 2,895 hours each winter.

500 pounds per hour x 2,895 hours x $ 8.00/thousand pounds = $ 11,580.00 per winter season.

SAVINGS REALIZED PER WINTER SEASON BY USING THERMOMEGATECH® VALVES:

$20,352.00 less $11,580.00 = $ 8,772.00 per year

SIMPLIFIED PAYBACK (R.O.I. RETURN ON INVESTMENT)

Assuming an installed cost of $ 500.00 for the ThermOmegaTech® valve to control the above system, the simplified payback on investment for this application is:

$8,772.00 ÷ $ 500.00 = 17.5 R.O.I.
