ACP/ACE aftercoolers of compressed air remove condensate and oil from the air stream during abrasive blast cleaning. Condensate and oils in the abrasive blast cleaning system lead to the caking of abrasive material and potential blocking of the metering valves, hoses and nozzles. Dry and cleaned compressed air prevents caking of abrasive material, increases performance and reduces maintenance costs. ACP/ACE coolers of compressed air are an efficient means of removing up to 95% of condensate and oil which are commonly present in compressed air. Dry air prevents moist abrasive material, which would lead to increased wear, downtime and extra servicing.
