Description
AB 14x16 water to air heat exchanger with 1" copper ports is designed for hydronic heating and cooling systems that require stable thermal transfer performance in a compact structure. The unit uses copper tubes and aluminum fins to support efficient heat exchange between water and airflow, making it suitable for residential, commercial, and light industrial HVAC applications.
Its multi-row tube configuration and dense fin arrangement help improve thermal contact area, while the steel casing and brazed structure provide structural stability under continuous operating conditions.
Key Features
Efficient Heat Transfer Design
Designed with 3 rows of 3/8" seamless copper tubes and 12 aluminum fins per inch, this heat exchanger supports effective thermal transfer in hydronic heating and cooling systems. The combination of wavy aluminum fins and copper tubing increases internal and external contact areas to improve heat exchange efficiency.
- Nominal capacity: 75,000 BTU
- Heating output up to 360,000 BTU/hour depending on system conditions
- Multi-row tube configuration for improved heat distribution
- Wavy fin structure increases airflow contact area
Copper and Aluminum Construction
Copper tubes and aluminum fins are combined to provide reliable thermal conductivity and practical durability for long-term operation. The epoxy-coated fins help improve surface hardness and wear resistance.
- 3/8" seamless copper tubes
- Aluminum fins with epoxy coating
- Improved resistance to fin wear and deformation
- Suitable for continuous heating and cooling applications
Reinforced Steel Casing
The unit features a steel-supported casing with furnace-brazed contact points to improve structural stability under varying operating temperatures and pressure conditions.
- Steel shell support
- Brazed edge and joint construction
- Stable structure for long-term operation

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.
