11. Ester oil will become saturated with moisture much faster than system with R 12 and mineral oil The compressor in an R 134a system will have to be replaced if the product has had low side leak R 134a refrigerant molecules are smaller than R 12 molecules This means that R 134a will pass more minor leaks and the rate of flow will be greater than for R 12 Therefore it is now more important than ever to follow good brazing practices Use a good grade of silver solder 45 silver solder is recommended leak detection R 134a system leaks can be pinpointed by means of an electronic leak detector or by bubble solution Electronic leak detectors for R 134a service are currently available from several manufacturers The least expensive models are non selective detectors that will detect any type of emission or vapor present regardless of its chemical composition Some non selective detectors designed for use with R 12 may have a much lower sensitivity when used with R 134a However newly designed detectors with good R 134a sensitivity are now available Be sure to consult with the manufacturer before selecting or using a non selective detector with R 134a Halogen specific detectors use a specialized sensor that allows detection of compounds containing chlorine fluorine bromine and iodine without being activiated by other species The major advantage of this type of detector is a reduction in the number of nuisance alarms Halogen
