COMPARATIVE ANALYSIS OF DYNAMIC DESCALER

CORROSSION AND SCALE DISSOLVING CAPABILITIES

......

Corrosion Testing According to ASTM G31Units are mils perYear (MPY)

As you can see Dynamic Descalers corrosion rates are 71% l ower than the competition.The above corrosion rates are according to the US NAVY Commercial Item Description [CID] Heat Exchangers Cleaning Compound. The maximum corrosion rate is 20mils per year [MPY].

Scale Dissoving AbiliyPut one Gram of Calcium Carbonate In Fifty Mils Of Cleaning Compound

Measure time to Dissolve

Scale dissolving ability is a test that measures how fast Dynamic Descaler will dissolvescale. The results show that Dynamic Descalers dissolved the calcium carbonate,which is the primary compound in boiler scale, much faster than our competitor.

Scale neutralizing ability is a titration thar measures how much the descaler solution will

dissolve. The maximum time allowed for this analysis is 1 hour .Dynamic Descalerdissolves 56 % more scale than the competitor.

Critical Anodic Current Density For Passivation of 70/30 Cu/Ni

Anodic Passive Region

Eb = 0.253 V

Conclusion Anodic Polarisation Testing on six 70/30copper/nickel samples in flowing natural seawater was

conducted. Based on testing and analysis, it was found that:

All samples pass current density criteria (10^6 A/cm^2) after the initial 21 days plus an additional 28 days. After immersion to BIO DSCALE (Dynamic Descaler), the experimental

samples passed the critical current density criteria immediately (< 1 day).

Immersion in BIO DSCALE (Dynamic Descaler) solution has a negligible effect on the nature of the passive film formed by seawater immersion of 70/30 copper/nickel

RE: DYNAMIC DESCALERA3

133225NSF Registration No.

Dear David Guttery:

NSF has processed the application for Registration of DYNAMIC DESCALER to the NSF RegistrationGuidelines for Proprietary Substances and Nonfood Compounds (2004), which are available atwww.nsf.org/usda. The NSF Nonfood Compounds Registration Program is a continuation of the USDAproduct approval and listing program, which is based on meeting regulatory requirements including FDA 21CFR for appropriate use, ingredient and labeling.

This product is acceptable for use as an acid cleaner (A3) in and around food processing areas, whereits use is not intended for direct food contact. Use of this product in food processing or handlingfacilities requires that all food products and packaging materials be removed or protected prior toproduct use. A potable water rinse of cleaned surfaces is required after use of this product. Whenused according to manufacturer's instructions, the cleaner shall neither exhibit a noticeable odor norleave a visible residue.

NSF Registration of this product is current when the NSF Registration Number, Category Code, andRegistration Mark appear on the NSF-approved product label, and the registered product name is included inthe current NSF White Book Listing of Nonfood Compounds at the NSF website (http://www.nsf.org/usda).The NSF Registration Mark can be downloaded from the NSF website, athttp://www.nsf.org/mark/download_marks.html.

NSF Listing of all registered Nonfood compounds by NSF International is not an endorsement of thosecompounds, or of any performance or efficacy claims made by the manufacturer.

Registration status may be verified at any time via the NSF web site, at http://www.nsf.org/usda. Changes informulation or label, without the prior written consent of NSF, will void registration, and will supersede theon-line listing.

Sincerely,
