Condensate Elimination System

Delta T Enclosure Air Conditioners dispose of condensate by routing refrigerant hot gas through a condensate boil off pan. This causes water to evaporate which results in:

  • Condensate being eliminated before it can escape the unit
  • Increased unit efficiency by pre-cooling refrigerant
  • Lower running amps make our industrial air conditioners more efficient
  • No need for inefficient external drain tubes or electric heaters
