Description
AB 10x10 water to air heat exchanger is designed for hydronic heating and cooling systems that require efficient thermal transfer in a compact form factor. It uses copper tubes and aluminum fins to transfer heat between hot or chilled water and moving air, making it suitable for residential, commercial, and light industrial HVAC applications.
This model features 1" copper ports, a multi-row tube configuration, and epoxy-coated aluminum fins for improved durability in long-term operating environments.
Operating Principle
The unit transfers thermal energy between circulating liquid and moving air without mixing the two mediums. Heated or chilled water flows through the copper tubes while air passes across the aluminum fin surface. Heat is transferred through the tube and fin structure into the surrounding airflow for space heating or cooling applications.
This design supports stable thermal performance while maintaining a compact footprint for HVAC system integration.
Key Features
Efficient Heat Transfer Design: The heat exchanger is built with 3 rows of 3/8" seamless copper tubes and 12 aluminum fins per inch to improve thermal exchange efficiency. The wavy fin structure increases the contact surface area between air and the fin surface, helping improve airflow turbulence and overall heat transfer performance.
Under suitable operating conditions, the unit supports heating capacities up to 42,000 BTU, with higher output depending on airflow, water temperature, and system configuration.
Copper Tube and Aluminum Fin Construction: Copper tubes provide strong thermal conductivity and reliable heat transfer performance, while aluminum fins help maximize surface area without significantly increasing overall unit weight.
The seamless tube structure supports stable fluid circulation and reduces the risk of leakage under normal operating conditions.
Reinforced Steel Casing: The external shell is supported with a steel frame structure for additional rigidity. Brazed contact points and reinforced edges help maintain structural stability when operating under varying pressure and temperature conditions.
Epoxy-Coated Fin Surface: The aluminum fins are coated with epoxy resin to improve resistance to moisture, oxidation, and surface wear. This coating also helps maintain fin integrity over extended use in demanding environments.

FAQ and Support
Tips for mounting Air to Water Heat Exchanger:
If your air system has an overheat sensor, be sure to install the Air to Water Heat Exchanger far enough away from it so that the heat from the exchanger won't interfere with the sensor's readings.
