Data Sheet
Micro Channel Heat Exchanger
Type MCHE D1900-C
Condenser – standard series
D1900-C is ideal for use in many different applications, such as chillers and commercial split/roof tops.
MCHEs have an ingeniously simple allaluminum design that is not only lightweight but also prevents galvanic corrosion.
The refrigerant-carrying tubes are formed to optimize heat transfer, enabling the production of more compact, but equally effective, cooling solutions. The smart louvered fin design maximizes surface contact, reducing the airside pressure loss, improving efficiency and reducing noise levels.
Features:
• Reduce refrigerant system charge
• Improve efficiency – More compact/better COP/increased capacity
• Cost - Less sensitive to …uctuations in raw material prices
• Better corrosion characteristics due to allaluminum design
