Rand-Air Aftercooler

After Coolers are heat exchangers for cooling the discharge from an air compressor. They use either air or water and are an effective means of removing moisture from compressed air. After Coolers reduce the amount of water vapor in a compressed air system by condensing the water vapor into a liquid form.

The After Coolers in the Rand-Air fleet use ambient air to cool the output air of the compressor at an output temperature of only 10°C higher than the ambient temperature. This cooling process causes the condensation of up to 80% of the moisture present in the compressed air, which is then separated thanks to an AS/MS centrifugal condensate separator installed at the After Cooler outlet.

The After Cooler consists of a heat exchanger with the finned coil, cooled by a high-efficiency axial fan mounted on a galvanized and painted sheet structure.

Our range can be used in conjunction with diesel or electric-driven air compressors ranging from 400cfm to 1000cfm, pressure ranges from 8 bar to 25 bar.
