Standard Features

• For use with structured packing only
• 2:1 turndown ratio
• Secondary trough spreads liquid and feeds enhanced baffle
• Enhanced baffle includes surface treatment for liquid spreading and serrated bottom to prevent liquid tracking
• Baffle alignment ensures complete wetting at bottom of first layer
• Elevated metering orifices provide fouling resistance
• Overflow protection
• Reduced drip point density allows for larger orifices
• Secondary baffle shields liquid from high-velocity vapor between troughs

Optional Features
