High-Quality Materials
The entire unit is copper brazed at edges and contact points, forming a durable and leak-resistant piece that withstands high pressure and temperature. CE certified for reliable quality.
Durable and Corrosion-Resistant
Features epoxy-coated fins, providing high hardness, wear resistance, and corrosion protection. This reduces internal water vapor scaling, promoting maximum heat exchange between air and fins. Suitable for operating temperatures of -40-356β / -40-180Β°C.
Efficient Heat Transfer
The heat exchanger generates up to 160kBtu per hour, with 12 aluminum fins per inch and 3 rows of 3/8" seamless copper tubes. The threaded copper tubes increase the contact area and capacity of the fluid medium, significantly enhancing the heat exchanger's performance.
Large Heat Exchange Area
With an effective heat exchange area of 18βx20β and 242 fins, this heat exchanger provides excellent heat transfer performance to meet various needs.
Tight and Leak-Proof
To eliminate the possibility of micro-leaks, the heat exchanger uses high-pressure vacuum brazing and undergoes rigorous leak testing, ensuring long life and high reliability.
