The simple Vysa-Frost330 frost protection system comprises a basic ON - OFF frost thermostat that monitors outdoor temperatures and switches the Vysa-Mat Classic heating mat ON when the air temperature falls to a critical level.

The Vysa-Frost 330 is a simpler, less sophisticated and cheaper system than the fully automatic Vysa-Frost850 snow and ice protection system and intended for a different application.
You should consult us if you have an application requiring a snow and ice melting solution or a frost protection system so that we can advise you correctly about what solution you require for the application.
