ARE DURACOOLŽ PRODUCTS GUARANTEED? DURACOOL LIMITED guarantees that DURACOOLŽ products will perform as efficient refrigerants, and will not harm any air-conditioning or refrigeration components and equipment if used in accordance with the manufacturer's directions and instructions. PRESSURE TEMPERATURE "A NATURAL SOLUTION TO A GLOBAL DILEMMA"

THE DIFFERENCES BETWEEN DURACOOLŽ AND HFC-134a DURACOOLŽ HFC-134a Negligible Global Warming Potential (GWP) = 8 Global Warming -GWP=1300 (USEPA) -GWP=3200 (Greenpeace) Non-Ozone Depleting Non-Ozone Depleting Organic materials only Synthetic, man-made chemicals Compatible with mineral and synthetic oils Operates with Synthetic oils ONLY. Not compatible with Mineral oils. Synthetic oils are highly hygroscopic. Energy Efficient Energy inefficient, even compared with CFC-12 Non-corrosive HFC-134a MSDS sheets disclose: "Contact with certain metals (aluminum..zinc..) may cause a violent reaction or explosion" "Incompatible..[with].. freshly abraded aluminum ( may cause strong exothermic reactions)." Lower operating head pressure High operating head pressure, even compared with CFC-12 Non-Toxic HFC-134a MSDS sheets disclose: "This product is harmful by inhalation" and "this product may cause cardiac sensitization" and "Hazardous Decomposition Products: halogens, halogen acids, and possibly carbonyl halides, such as phosgene. These are toxic and corrosive". and "Individuals with preexisting diseases of the central nervous system or cardiovascular system may have increased susceptibility to the toxicity of excessive exposures." Adds life to air-conditioning and refrigeration equipment Extensive evidence of multiple equipment (particularly compressors) failures. EQUIVALENTS. DURACOOLŽ products are extremely efficient. DURACOOL 12aŽ requires only 35% of the charge, by weight, of CFC-12 (R-12), or 40% of the charge, by weight of HFC-134a (R-134a). DURACOOL 22aŽ and DURACOOL 502aŽ require only 40% of the charge, by weight, of R-22 and R-502, respectively. This is interpreted as follows: DURACOOL 12aŽ 6 ounce can = 17 ounces of CFC-12 (R-12) or 15 ounces of HFC-134a. 30# refrigerants cylinder containing 12 pounds = 34 lbs of CFC-12 (R-12) or 30 pounds of HFC-134a. 50# refrigerant cylinder containing 20 pounds = 57 lbs of CFC-12 (R-12) or 50 pounds of HFC-134a. DURACOOL 22aŽ 50# refrigerants cylinder containing 20 pounds = 50 pounds. HCFC-22 (R-22) or 48.5 pounds of HFC-134. DURACOOL 502aŽ 50# refrigerant cylinder containing 20 pounds = 50 pounds of CFC - 502 (R-502).
