A 16 x 16 inch water-to-air heat exchanger with 193 aluminium fins and three rows of 3/8 inch copper tubes, delivering up to 160k BTU per hour for outdoor wood furnaces and forced-air heating
The VEVOR C16 specialty appliance is a copper-brazed heat exchanger built for outdoor wood furnaces and forced-air heating systems. Its 16 by 16 inch plate area and 193 epoxy-coated aluminum fins serve installers who need a compact, high-surface-area core for hydronic-to-air heat transfer. The unit weighs 13.65 lb and fits within a 21.57 by 16.06 by 3.62 inch envelope.
Rated for 80K BTU with a peak capacity of 160kBtu per hour, the exchanger uses three rows of 3/8 inch seamless copper tubes and twelve fins per inch to move heat between fluid and air streams. It operates from minus 40 to 180 degrees Celsius and withstands a maximum working pressure of 2.5 MPa, making it suitable for high-temperature hydronic loops without leaks.
This model replaces smaller or single-row cores where the 16 by 16 inch footprint is available but greater fin count and copper tube rows are needed for higher output. The jump is worthwhile when the existing exchanger cannot meet the 80K BTU design load or when corrosion has degraded fin efficiency in an outdoor furnace installation.

Slide the 21.57 x 16.06 inch frame into the duct opening so the 3.62 inch depth sits flush, then seal the perimeter with foil tape; the 12 fins per inch spacing stays clear because the copper ports protrude only on the header side.
The epoxy coating on the aluminum fins resists scaling, but mineral deposits can still narrow the 3/8 inch copper tubes; flushing the loop annually keeps the 2.5 MPa pressure rating intact.
When the supply water exceeds 180 °C or the air flow cannot pull 160 kBtu per hour across the 193 fins, the exchanger hits its thermal limit before the copper structure does.
