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 -40-356℉ / -40-180°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 20”x20” 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.
