About this file
This document is a Sole Source Form and Exemption Revision Form from Sarasota County's General Services Department for a procurement with NALCO Company LLC. The procurement is for preventative maintenance services for a proprietary 3D TRASAR system used in HVAC condenser water and closed loop water systems at various county locations. The original sole source approval (SS 2061) is being revised to extend the contract for one year and increase the estimated expenditure amount from $62,924.40 to $67,958.35. The 3D TRASAR system, which has been installed in county buildings since late 1998, utilizes specific equipment, chemistry, and application methods protected under US Patent 6,369,894.
The sole source justification is based on the proprietary nature of the NALCO 3D TRASAR technology, which is produced exclusively by NALCO for its customers. The county argues that changing systems would be cost-prohibitive, as the current product is used nationwide and recommended by leading HVAC manufacturers. The procurement is within the $150,000 threshold that allows direct approval by the Procurement Official without additional Board of County Commissioners authorization. The documents include a technical memorandum from NALCO Water (an Ecolab Company) detailing the unique modular fluorometer technology used in the 3D TRASAR system, which is designed to control industrial water systems through specialized optical measurement techniques.

Dear Valued Nalco Customer, This information is provided for your use regarding the proprietary nature of Nalco Company 3D TRASAR technology. 3DT TRASAR, which utilizes specific equipment, chemistry, and application, is proprietary and is produced only by and for the benefit of Nalco customers. 3D TRASAR is protected under US Patent 6,369,894. An abstract for the patent is posted below:
Modular Fluorometer Abstract
Described and claimed is a modular fluorometer and a method of using same to control an industrial water system, wherein said modular fluorometer comprises: one or more units with each unit comprising: a channel comprising an optically appropriate cell through which a water sample flows; a light source positioned outside said optically appropriate cell; an optional excitation filter positioned between the light source and the optically appropriate cell; a reference detector positioned outside the optically appropriate cell; an emission detector positioned outside the optically appropriate cell; an optional emission filter positioned between said emission detector and said optically appropriate cell; wherein if more than one unit is present in said modular fluorometer, said optically appropriate cells through which said water sample flows are aligned such that only one channel through which a water sample flows exists in said fluorometer.
