1. Product Overview: Modular Integrated Cooling offering

The Centac Cooler CV1A is a core module of Ingersoll Rand's Centac series centrifugal air compressors, specifically configured for industrial compressed air system setups. This cooler features a compact modular design that integrates the main cooler, intercooler, aftercooler and air filtration system setup on a single chassis, significantly reducing footprint and simplifying installation.

Its primary function utilizes advanced heat exchange technology to transfer heat from compressed air to cooling media, ensuring stable operation within flow rates of 720-51,000 m³/h and pressure ranges of 0.7-22.5 kg/cm². The CV1A employs graphite-sealed floating rings for zero-leakage sealing of both air and oil media, complemented by tilting pad bearings and oil film lubrication to minimize mechanical friction losses.

The patented sleeve-type air cooler design features air flowing through tubes while cooling water circulates outside in counterflow configuration, with specialized internal fin structures that keep low pressure loss while achieving industry-leading heat transfer overall efficiency. The system setup supports expandable air filtration from 4 micron down to 0.5 micron levels for clean air requirements in pharmaceutical and food industries.
