CLS-AP
Closed Loop System Heat Transfer Add Pak, Glycol Based – Inhibitor PackageProduct Description and Applications
The Closed Loop System Heat Transfer Fluid Add Pak (CLS-AP) is for use with ethylene or propylene glycols, and may be used to make heat transfer fluids for these applications: HVAC systems, food processing heating and cooling units, process heat transfer systems, and many more.
CLS-AP contains only food-grade ingredients. When it is used with the appropriate grade of propylene glycol which is generally regarded as safe (GRAS) by the FDA/USDA, the heat transfer fluid produced can be used in applications where there is a possibility of incidental contact with food or beverage products in a processing facility. CLS-AP mixes readily with glycols at temperatures as low as 50ºF, and can be stored without crystallization above 60ºF.
The ingredients in CLS-AP inhibit corrosion of all metals commonly found in HVAC systems, and also are compatible with most plastic construction materials. Corrosion inhibition is provided in several ways: 1) metals are passivated, or protected, by thin, non-fouling molecular coatings ionically bonded to the surface; 2) pH of the glycol-water solution is buffered by an acid-neutralizing ingredient which acts to maintain the desired level of alkalinity; 3) dispersing-suspending agents help prevent scaling and fouling.
Propylene or ethylene glycol-containing CLS-AP may be formulated to any concentration, with water containing up to 300 ppm (total) hardness (salts of magnesium, calcium, etc.). Higher hardness levels may cause excessive inhibitor consumption, scale deposits, and metal pitting.

Quality Control
To ensure quality control and assurance, all blending is controlled under ISO 9002 standards. Each individual batch rigorously tested for conformance with product and industry specifications prior to storage, packaging, or shipment. This laboratory analysis is thoroughly conducted by Additives Inc. A Certificate of Analysis for each lot is produced and is available to customers.
Technical Support
It is always necessary to confirm that your products meet the required specifications. Additives Inc.'s laboratory and chemists are available to test any antifreeze products containing Additives Inc.'s Add Pak as a complimentary service. In this way, Additives Inc. can help you to establish or confirm your quality control and assurance program. However, we will not warranty any Additives Inc.'s product if the blending procedure is not properly followed and/or if the glycol being used contains impurities that do not allow the final product to meet the minimum ASTM standards.
Guarantee - Warranty
Additives Inc. will only warranty our products if instructions and outlined procedures are followed. It is always necessary to confirm that your product meets the required specifications using the ASTM recognized tests and standards. Should you have a problem meeting your required specifications, Additives Inc. technical personnel will test your glycol, while you establish use levels of our products.
