Regular rent gas bottles are not intended for refilling by the user. Not even to mention the security and legal implications. We can agree entirely with this, but Safe Fill cylinders are specifically designed to refill. Our cylinders produced by Hexagon Ragasco have an unparalleled level of safety and the following functions:
Up to 80% filling, the pump automatically shuts off if the 80% charge is achieved.
An additional check valve if you accidentally forget to turn off the tap after filling.
Over pressure protection when there excessive pressure in the cylinder occurs is blown off the pressure.
Can not explode in a fire. Tests have shown: If a Safe Fill bottle stands in a fire, it will begin to sweat and let the gas escape gradually, but the bottle will never explode like a steel cylinder can do.
