ZCryo is a cold air device to minimize pain and thermal injury during laser and dermatological treatments and for temporary topical anesthetic relief for injections. Its ability to cool the epidermis before, during and after the application of laser energy, without interfering with the laser beam makes it distinct from other cooling methods. It is easy to operate and comes with a large display indicating all treatment parameters. It is cost efficient (no consumable or additional costs), practical (customized glass shelf where you need it for a laser, smoke evacuator or accessories) and has an easily operable tactile glass keyboard. It has an optional articulating arm that facilitates hand-free operation. You can connect its light weight application hose to selected laser hand-pieces. Additionally, you can regulate the air flow as per your requirements. The economic room air is filtered and cooled down to -30°C by closed cooling circuit. A total of nine fan speeds are available. The treatment time can also be adjusted by pressing a button and it can be operated for a full day without any downtime.
