Snow Dragon uses state of the art heat technology for our snowmelting equipment. Models include the SND580 that is designed for use on the top deck of a parking garage as well as standard snowmeting sites. The SND900 is the most popular model and is used on city streets, parking lots, hospitals and stadiums. The SND1800 is for the serious snow removal applications pulled by a semi truck. The SND5400 is overlength and overwidth primarily being used in larger airport markets and snow dumps.
