Dear Mr. Brooks,

We have measured the current draw of your chillers before and after Frigi-Tech oil treatment was added. The results are impressive:

Before Frigi-Tech oil treatment:

Phase 1     Phase 2     Phase 3
  140           145            135

After Frigi-Tech oil treatment:

Phase 1     Phase 2     Phase 3
  124           128            122

((((15 Amps) X (460 Volts) X (1.732))/1000) X 24 Hrs/Day X 365 Days/Yr.
            104,689 KWH

104,689 KWH/Yr. X $.0718 = $7,516.67 savings per year on the lead chiller.

(((15 Amps) X (460 Volts) X 1.732))/1000) X 3 Hrs/Day x 365 Days/Yr.
            13,086 KWH

13,086 KWH/Yr. X $.0718 = $939.57 savings per year on the lag chiller.

Total Annual Savings = $7,516.67 + $939.57
                                 = $8,456.24

We are very pleased with the savings at Georgetown Hospital.

Respectfully,
