IN LINE WITH OUR POLICY OF CONTINUOUS PRODUCT DEVELOPMENT ALL PRODUCT DESIGN IS SUBJECT TO CHANGE WITHOUT PRIOR NOTICE
The latest development in extrusion technology allows a much higher fin height to fin spacing
ratio. This provides much greater performance in a force cooled environment than has hitherto
been possible with standard extrusion. This enables the thermal engineer to make further space
and weight savings as it is now possible to achieve higher performance from a smaller
volume.
