FINNED HEAT EXCHANGER - Efficient Transfer, Custom Sizes
Six core advantages that keep your refrigeration system protected around the clock
TP2 copper tubes with aluminum fins: corrosion-resistant, high-conductivity copper with lightweight, large-area fins.
Tube pitch 21/25/19.05mm, column pitch 12.5-21.65mm, tube Φ5.0-Φ9.52mm from small to large duty.
Optimized fin spacing and pattern enlarge area and raise the air-side coefficient.
Plain, wavy and louver fins suit different air velocities; protective coatings optional.
Fin spacing adjustable 1.2-5.0mm to balance transfer efficiency and air resistance.
Choose plain or hydrophilic foil; the hydrophilic coating prevents water bridging in humid conditions.
