Ready-to-run 4-channel high-flow dosing \u2014 scalable and quiet<\/strong><\/p>\n

The GHL Doser 3 Maxi SA+EXT Set combines one Stand-Alone (SA)<\/strong> and one Extension (EXT)<\/strong> unit for a 4-pump<\/strong>, high-capacity dosing solution. The SA<\/strong> operates completely independently with integrated LAN, Wi-Fi, and USB<\/strong> for control via app, cloud, or PC software, plus sensor ports<\/strong> (up to 2\u00d7 level<\/strong>, 1\u00d7 temperature<\/strong>) for fully autonomous ATO and automatic water changes. The EXT<\/strong> adds two more pumps with identical performance and silent operation, connected via PAB (ProfiLux Aquatic Bus)<\/strong> for centralized control.<\/p>\n

Highlights<\/strong><\/p>\n

    \n
