OMI RA and A SERIES: HEAT EXCHANGER SOLUTIONS
Aftercoolers are critical in compressed air treatment, as they cool hot air to condense water vapor, thereby preventing corrosion and protecting filters and dryers from overheating.
Air-cooled series (RA and RA-P)
The RA series, featuring a wide range of heat exchangers and powerful fans, is the most common solution:
Performance: Capable of reducing compressed air temperature from above 120℃ to just 3℃ above ambient temperature.
Condensate Management: Condensate is separated via a separator installed at the heat exchanger outlet.
RA-P (Pneumatic): Compared to the electric version, this type uses a portion of the compressed air to drive the fan. This series is equipped with a silencer and a lubricating filter for increased reliability and lower noise levels.
Design: The series are available with 60 Hz power supply, NPT/ANSI connections, and options without separator, motor, or frame.
Water-cooled series (A and AV)
Water-cooled aftercoolers are ideal for particularly high inlet temperatures:
Design: Consists of two main parts: a high-efficiency shell-in-tube heat exchanger and a cyclone separator.
Delivery Temperature: The maximum air inlet temperature +200℃ has been increased to.
Flexibility: Also available with vertical installation (AV series) upon request. Available with a separator-less option and NPT/ANSI connections.
Technical Specifications: They operate with a maximum operating pressure of 16 bar, and special consultation is required for water temperatures below +1℃.
