The Recharger 150XLHD is an 18.5-in. (470-mm) tall, low profile chamber that is typically used for installations with depth restrictions or when a larger infiltrative area is required. The Recharger 150XLHD has the side portal internal manifold feature—there are two side portals on each side of the chamber, and HVLV FC-24 feed connectors are inserted into them to create the internal manifold.
