I would like to thank you for your tremendous help in getting a Safe D Scale demonstration arranged at the Mayport Naval Station for 12-14 May 1998. The characteristics of the Navy necessitate water to be used in cooling many pieces of equipment. For this reason we have struggled for decades in cleaning scale build-up. Many sailors have spent hours chipping or acid cleaning tubes and machinery encrusted with scale through normal operation. Using Delta Products Group Safe D Scale will decrease cleaning time and be used far more effectively than an acid cleaning or subjecting equipment to hydroblasting.

It is extremely invaluable that your product is non-toxic, non-flammable, non-corrosive, non-hazardous and is biodegradable. Many technicians are still amazed your product is safe enough to hold in your open hand and can be disposed of down regular sewer systems with a fresh water flush.

I find it a pleasure to come across an environmentally concerned company with numerous products designed to completely and safely remove and prevent water scale, rust, lime and biological deposits formed in any water heated, water cooled or water operated equipment. I can assure you that we will investigate use of your products to clean and treat heat exchangers, boilers, condensers, compressors, potable water piping, firemains, urinals, and even galley dishwashers and ice machines. In fact, I am developing a cost-benefit analysis to show other Naval Commands how to clean scale at a lower cost and protect the environment.

With low cost, essential environmental and safety benefits, rapid cleaning times, and potential emergent dry docking expense savings, Delta Products Group Safe D Scale and related products will be examined by agencies requiring upkeep of all water heated or cooled equipment.
