Aftercoolers

About Aftercoolers

Aftercoolers are heat exchangers for cooling the discharge from a compressor. They use either air or water and are an effective means of removing moisture from compressed air. Aftercoolers control the amount of water vapor in a compressed air system by condensing the water vapor into liquid form. In a distribution or process manufacturing system, liquid water can cause significant damage to the equipment that uses compressed air. An aftercooler is necessary to ensure the proper functioning of pneumatic or air handling devices that are part of process manufacturing systems.

Aftercoolers can use either air-cooled or water-cooled mechanisms. A compressor aftercooler may be a stand-alone unit located downstream of the compressor, or may be integrated into the compressor itself. Water-cooled aftercoolers or heat exchangers are fitted into a pipeline and use a moisture separator and drain valve to extract the water from the compressed air moving through the pipe. The moisture separator uses centrifugal force to separate out the moisture and solids from the compressed air and they exit the system through a drain. An air-cooled heat exchanger uses ambient air to cool hot compressed air. An air cooled heat exchanger use a motor-driven fan to force the ambient air over the cooler, removing the heat from the compressed air.

Products & Services Related to Aftercoolers

Compressed Air and Vortex Cooling Tubes
Compressed air and vortex cooling tubes are used for spot heating or cooling applications.
Cooling Towers
Cooling towers are defined as any open water recirculation device that uses fans or natural draft to draw or force air to contact and cool water by evaporation.
Cooling Tunnels
Cooling tunnels ensure controlled temperature reduction in both batch and continuous process systems. They are similar to air convention ovens, but have no heating capacity.
Desuperheaters
Desuperheaters are used to cool steam in power plants.
Evaporative Coolers
Evaporative coolers are cooling devices that use the evaporation of water into the air to cool the air temperature. They are sometimes called air coolers, desert coolers or swamp coolers.
Heat Exchangers
Heat exchangers are commonly used in a wide variety of industrial, chemical, and electronics processes to transfer energy and provide required heating or cooling.
Heat Pipes
Heat pipes are self-contained heat pumps that can transport heat at high rates over fairly substantial distances with no external pumping power.
Heat Pumps
Heat pumps are reverse cycle air conditioners. They use a compression cycle system to supply heat or remove heat from a temperature-controlled space.
Industrial Cooling Systems and Equipment
Industrial cooling systems and industrial cooling equipment includes air-to-air, liquid-to-air, and liquid-to-liquid heat exchangers; ducts and/or pipes; and other devices for removing heat from a system that contains a heat source.
