Get better technology – plus years of proven reliability

Brazed Aluminum Microchannel (BAM™) coils are constructed of extruded aluminum tubes containing many small refrigerant ports that greatly enhance the internal wetting surface, compared to copper tubes. Brazing the microchannel tubes to highly engineered aluminum fins creates a robust, compact assembly that delivers better performance and simpler field maintenance than tube-in-fin (TIF) designs.

BAM™ technology was introduced in automotive air conditioners in the early 90s, and has been dominant since the late 90s. It has demonstrated strength, durability and corrosion resistance in the demanding automotive environment, while significantly reducing warranty claims.

A BAM™ coil can deliver much greater heat-exchange capacity than TIF technology in the same space. Or, a BAM™ coil can be smaller than a TIF coil with the same capacity. In either case, BAM™ coils are significantly lighter.

BAM™ delivers other advantages, too:

• The smaller internal volume of BAM™ coils can cut the refrigerant needed to charge the system by up to 45%.


• BAM™ coils are stronger and less prone to damage


• BAM™ coils are more corrosion-resistant


• Higher coil efficiency also lets you use smaller cabinets, reducing fabrication and shipping costs.


• All-aluminum structure avoids the volatility of copper prices.

Get better mechanical strength

BAM™ technology delivers greater mechanical strength than TIF designs, because they are brazed rather than just pressed together. For example, BAM™ coils can be pressure-washed without damage.

Get better corrosion resistance

Current BAM™ technology uses passivated aluminum surface coatings and non-galvanic plumbing connections to deliver significantly better corrosion performance than TIF coils. The superior corrosion resistance of BAM™ technology is especially beneficial in coastal areas where salt spray often shortens the useful life of TIF coils.
