Cooler

The 7X12982 is a part number for an air cooler used in centrifugal air compressors. It primarily serves as a 1st-stage cooler in multi-stage compressor systems like the CV1 model series. 

Application: Functions as either an intercooler (cooling air between compression stages) or an aftercooler (final cooling before use) for centrifugal compressors.

Material: Typically constructed from high-quality copper for superior thermal conductivity (up to 30% higher efficiency than aluminum) and corrosion resistance. Some variants may use copper-nickel (CuNi) or brass tubes.

Construction: Features a tube-and-fin design, consisting of a tube sheet, casing, and water chamber.

Durability: Often built to meet ASTM B322 standards for corrosion resistance, making it suitable for harsh industrial environments.
