A TFS-55 based Bias-90 configuration retrofit option is also offered by Fluenta for installations which currently have 3″ flanges installed at 90 degrees to the pipe. This Bias-90 retrofit option can accommodate pipe sizes ranging from 10″ to 42″ and is intrusive in nature, meaning it is more affected by fouling as compared to the Lateral-45 configuration. Such a configuration is usually used as a last resort to circumvent space constraints and in some cases difficult gas compositions as reduced tip-to-tip distances can be achieved.
