1. Introduction
 MCHE use brazed aluminum construction and is based on the unique micro channel technology, which consists of three components: a flat micro channel tube, fins and two refrigerant manifolds joined together in a single coil. The design provides greater efficiency than traditional mechanical tube and fin heat exchanger designs.
 2. Benefits a. Little galvanic corrosion
 b. Refrigerant charge reduction - up to 70%
 c. Long life alloy can withstand aggressive environments
 d. Helps manufacturers meet high SEER (Seasonal Efficency Ratio) and HSPF (Heating Seasonal Performance Factor) requirements.
 e. MCHE is more than 30% higher heat transfer efficency
 f. Up to 30% lower airside dP
 g. MCHE is lighter in weight, smaller in volume: up to 50%;100% Aluminum, easy to cycle
 h. Minimum performance decrease (100% brazed)
 i. Special design for good refrigerant distribution
 j. Special fin design for good water drainage
