The FreezMed N₂O cartridge is refillable. When it runs low, your clinic sends it back through the official Returning Program and receives a pressure-checked, refilled cartridge in return — no in-clinic refilling, no downtime guesswork.
Contact FreezMed and we send the official Refill Program return box straight to your clinic.
Place the cartridge safely inside the official return package and seal it for shipment.
Post the package to our Tehran facility. We check pressure, refill with N₂O, inspect, and return it to you.
Fill in your clinic details to generate a refill request label. Print it and place it inside the package you send back to us — it lets us match your cartridges to your account the moment they arrive.
