We are sure you are aware of other companies that market hydrocarbons that contain the “rotten egg or sulfur odor”. This smell comes from the sulfur in a blend that is unrefined or from an additive called ‘mercaptin’ which some companies add for the odor itself. Mercaptin is made from sulfur. When sulfur is introduced to moisture, it becomes an acid.
Enviro-Safe™ 502a Refrigerant is different, because it is highly refined! Enviro-Safe does not contain the “rotten egg, sulfur, propane” odor. We add a fresh “Pine Scent” to our refrigerant to assist consumers in leak detection.
Enviro-Safe™ 502a Refrigerant is a non-ozone depleting product and is completely safe for the environment.
