Copper & Brass Heat Exchangers

Copper & Brass Heat Exchangers
3A Clizen manufacturers copper and brass heat exchangers and heater cores that work by increasing the temperature of the automotive interior by heat exchange. When water or other liquid that has been heated in the engine circulates through the heater core, it optimizes the temperature by heat exchange between the tubes and fins. We manufacture the copper and brass heater cores in 32, 29 and 22 inch widths.
