COM 66

Our new COM tube is 66mm in depth,compared to our current range, which offer27 mm and 45 mm depth. This increases the heat transfer between the air and the oil. Knowledge we invest in productdevelopment New louvered air fin increasesheat transfer A powerful combination By combining a 66mm tube and our newtype E air fin, we can achieve a 25-50% increase in cooling performance. This isessential to meet todays ever increasingdemands on cooling performance. By engaging in an intensive programme ofdevelopment and collaboration with ourcustomers, we have reached a proven level of expertise in calculating and sizing cool-ers. We have invested this wealth ofexperience into further product develop-ment and we can therefore claim that one of the most efficient, most robust, flexibleoil coolers currently available on the market,the Setrab COM, has now become evenbetter. Our new 66 mm wide tube and thenew E- and F-type air fins are examples ofour development work. Through an intensive development pro-gramme we have improved the character-istics of our louvered type E fin. The result is a 15% increase in cooling efficiency for atypical fan. For a given core front air velocity,the performance increase is 20%.
The new COM 66 cooler has top and bottomplates that protect the outermost air fins, leadingto a neater design with virtually flat surfaces attop and bottom.With the wider 66 mm tube profile the cooling effect increases by 10-30% for an equivalent cross-sectional area.
