Miniature Liquid Cooled Chiller for Skin Cooling

broken image

Rigid has been looking for novel solutions, we are creative and capture new technologies. Our success is based on continuous involvement in research and development.

The Rigid Liquid Chiller Module is a high performance used for Medical-Aesthetic skin cooler, use during dermatological and surgical laser procedures. Medical-Aesthetic device is intended to minimize pain and thermal injury during laser and dermatological treatments and for temporary topical anesthetic relief for injections. As we all known, medical device required precision thermal management and strictly temperature control. Unlike other cooling methods such as contact cooling, cryogen spray or ice packs, Rigid custom cooling systems provide the epidermis before, during and after laser energy has been applied without interfering with the laser beam.

Rigid is proud to announce the availability of 24 volt DV1920E-C (Coaxial st. st.). With the precision thermal control method provided by Rigid Technology, medical aesthetics market is able to provide non-invasive devices, which reduce patients the incidence of temporary side effects like redness and erythema, protecting the epidermis and reducing any discomfort.
