Why do I need an aftercooler?
An aftercooler provides dry compressed air, preventing blockages in the blast pot and improving the quality of the blasted surface.
Efficient blasting with superior results starts with dry compressed air!
Compressed air from the compressor is naturally hot and contains moisture. As it cools in the blast pot and hoses due to the lower ambient temperature, this moisture condenses into water droplets. This condensation can lead to blockage and clogging of the blast pot and can affect the machine's control valves. Moreover, the moist air leads to poorer blasting results and unwanted residues that can cause problems in subsequent production processes such as paint spraying, for example.
Start off with cool air!
To effectively dehumidify compressed air, an aftercooler is essential*. By cooling the air to around 9˚C above ambient temperature, moisture vapour condenses into water droplets. These droplets are removed by the aftercooler's centrifugal separator and can be discharged. In addition, optional compressed air filters of 1 and 0.01 microns can remove oil and other contaminants, ensuring optimum air quality for blasting operations.
* Important to emphasise: using only moisture separators and/or filters is not sufficient to dry compressed air when water is still present in vapour form (and not as droplets). An aftercooler is therefore essential to cool down the air first.
Gritco air coolers are the key to dry air
Professional blast cleaning with a controlled, continuous abrasive flow and a high-quality blast result starts with dry air. That is why Gritco manufactures a comprehensive range of aftercoolers designed to prevent breakdowns and downtime and provide the best possible air quality for small, medium & large blasting systems and other compressed air equipment.
