- 【Excepetional Performance】The heat exchanger has a capacity of 75,000 Btu. Depending on the application, the heat exchanger can produce up to 360kBtu of heat per hour, with 12 aluminum fins and 3 rows of 3/8" seamless copper tubes per inch. The combination of wavy fins and seamless copper tubes, which enhanced contact areas both inside and outside the tubes, results in a 10-20 percent increase in heat transfer performance, maximizing heating or cooling efficiency.
- 【Premium Material】Our heat exchangers are supported by steel shells, and the edges and contact points are base brazed, which is very solid and not easily affected by high pressure and temperature. Copper and aluminum are highly conductive materials, which make the heat exchanger have good performance and economy in heat transfer and cooling.The fins are coated with epoxy resin, which improves the hardness and wear performance of the fins，prolonging the service life of the fins.
- 【Energy-efficient and Affordable】Our water-air heat exchangers allow for water-air heat exchange movement through a variety of sources - boilers, solar panels, etc.This means you can utilize a variety of renewable energy sources and save energy.
- 【Convenient Installation】This new type of heat exchanger is easy to install, with a variety of options available. It can be directly connected to the pipeline and fixed with clamps; it also can be directly welded to the pipeline and adapters or be connected with rivets to meet meet a multitude of installation needs.
- 【Multiple Applications】Water-to-air heat exchanger offers a high level of thermal efficiency and durability in a compact & lightweight unit, which maximizes space saving, suitable for Outdoor Wood Furnaces, Residential and Commercial Heating and Cooling, Hybrid Systems, Air Conditioning, Inverter Cooling, and so on.
