  • New 6 watt heater ports provide 50% more heat to resist frost build-up from humid air entering freezer
  • Thermostatic control protects unit from heating during times when walk-in has no refrigeration
  • Low-profile, exterior screened hood protects against infestation
  • Unique cluster design makes installation easy
  • Accommodates any wall thickness from 3-1/2 inches
