Brymill Cryogenic Systems has been one of the world s leading manufacturers of handheld, liquid nitrogen cryosurgical and cryospray devices since 1966.With patented design features, Brymill s CRY-AC and CRY-AC-3 handheld cryo units provide safety, versatility and control for precise and effective medical and veterinary cryosurgery as well as industrial applications of liquid nitrogen, such as in the testing and repair of printed circuit boards. Liquid nitrogen cryosurgery with a cryogun is the coldest, most effective, and most versatile cryosurgical technique available with temperatures reaching as low as -196 C. LN2 applied with a cryogun is much colder and therefore more effective than LN2 applied with a swab (-20 C), nitrous oxide (-75 C) and disposable cold sprays (-55 C to -70 C). CRYAC and CRY-AC-3 devices are used to treat a variety of common skin lesions, including warts, actinic keratoses, seborrheic keratoses, molluscum, skin tags, age spots, genital warts and skin cancer.
