Benefits

  • No galvanic corrosion (100% aluminum)
  • Refrigerant charge reduction – up to 70%
  • Long life alloy for very aggressive environments
  • Helps manufacturers to meet high SEER (Seasonal Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) requirements
  • MCHE is more than 30% higher HT efficiency
  • Up to 30% lower airside dP
  • MCHE is lighter in weight, smaller in volume: up to 50%
  • 100% Aluminum, easy to cycle
  • Minimum performances decrease with lifetime (100% brazed)
  • Special tube bending structure for A-coil
  • Special desing for good refrigerant distribution
  • Special fin desing for good water drainage
