VEVOR Water to Air Heat Exchanger, 22 x 22 in Finned Tube HVAC Heat Exchanger Coil with Copper Tubes & Aluminum Fins, 190K BTU Output for Outdoor Wood Furnace, Hydronic Heating & Cooling Systems

Copper Tube and Aluminum Fin Construction for Maximum Thermal Conductivity

With its seamless pure copper tubes and high-density aluminum fins, the VEVOR 22×22 finned coil water to air heat exchanger delivers excellent thermal performance. Copper naturally transfers heat quickly from the fluid circuit to the surrounding airflow. This helps transfer heat efficiently between the circulating water and airflow.

The seamless, one-piece design of the copper tube eliminates weak spots that might occur in joined or welded options, helping improve durability under changing temperatures and operating pressures. With aluminum fins that maximize surface area, this coil maintains efficient heat transfer even under high stress or during continuous operation. This helps maintain consistent performance during long-term use.

190K BTU Output Capacity for High-Demand Heating Applications

This heat exchanger can handle up to 190,000 BTU/h of heat, making it ideal for demanding home and light-commercial applications that require a steady flow of hot air. The output capacity quickly and efficiently heats a room, whether it is part of a forced-air furnace, a hydronic air handler, or a big workshop heating system.

This unit performs better than smaller coils in the same line because it has a 22×22-inch plate area and three rows of copper tubes. It is well-suited for applications that require higher heating capacity. This rated output is best for installations covering large farm shops, commercial grow rooms, or residential systems with multiple zones.

Finned Coil Water to Air Heat Exchanger with 266-Fin Surface for Superior Heat Transfer

This finned coil water to air heat exchanger has 266 aluminum fins. These fins greatly increase the contact area between the coil and the moving air. As air passes over the fin surface, the increased contact area improves heat transfer efficiency. This directly leads to higher efficiency and faster thermal response times across the whole system.

Three rows of 3/8-inch copper tubes hold the fins in place across the entire 22×22-inch heat transfer area. This three-row depth ensures that the circulating fluid and airstream have enough time to interact, even at high blower speeds. This makes a coil that works well in many different situations, so you do not need big fans or pumps to compensate for it.

Vacuum Brazing Technology and Leak Testing for Long-Term Reliability

There is an industrial process called high-pressure vacuum brazing that joins copper tubes to aluminum fins. This makes metallurgical bonds that are stronger and better at keeping air out than regular mechanical joining methods. This process eliminates flux residue at the joint interface and ensures full contact between the tube and fin collar, ensuring consistent heat transfer throughout the coil.

Each heat exchanger undergoes strict leak tests before it leaves the plant to ensure that all its connections and joints are secure during operation. The fact that this production process can handle a maximum working pressure of 2.5 MPa (362.6 psi) demonstrates the structure’s robustness. Leak testing helps verify the integrity of the coil before shipment.

Epoxy-Coated Aluminum Fins for Scale Resistance and Extended Service Life

The aluminum fins of this heat exchanger have a high-hardness epoxy coating that helps resist corrosion and surface wear. In open-loop or outdoor wood stoves, or in other hydronic systems where water chemistry changes, this coating helps maintain fin efficiency by preventing mineral deposits from filling the gaps between the fins.

The epoxy coating not only protects against scale but also adds an extra layer of protection against corrosion and handling damage. The unit is designed to operate in temperatures ranging from -40 to 356°F without compromising its shape or performance. This is made possible by the galvanized steel mounting frame, which provides stable mechanical support and rust resistance.

Finned Coil Water to Air Heat Exchanger Compatible with Multiple Hydronic Systems

Many types of systems can use the VEVOR finned coil water to air heat exchanger. It works well in outdoor wood furnaces, hydronic heating loops, forced-air handlers, hydroponic grow room climate systems, residential HVAC retrofits, and hybrid heating configurations. The standardized 1.1×1.4 in copper inlet and outlet ports fit into most common plumbing configurations with minimal adaptation required.

There is a pre-drilled galvanized steel mounting frame that facilitates installation and allows the frame to be held inside air handler enclosures or duct systems. The unit weighs 23.4 pounds and measures 27.4 by 22.0 by 3.5 inches, so it is easy for one person to place in most air handler cabinets. It has a good balance between output power and size.

Galvanized Steel Frame and Standardized Port Size for Straightforward Installation

The galvanized steel frame provides structural support during installation and operation, so the copper tube connections do not have to withstand stress from movement or vibration. In both indoor machinery rooms and outdoor enclosures, the galvanized finish helps prevent rust and corrosion, so the frame will remain structurally sound for years to come.

The copper ports for the inlet and outlet are 1.1 by 1.4 inches (28.6 by 35 mm), the same size as most hydronic fittings used in homes and small businesses. The standardized port size simplifies connection to compatible plumbing systems. Installers working on new builds or retrofits will find that the frame design and port placement make it easy to drop the unit into suitable air handler cabinets.
