Description
The KH Director EXT IL PnP System is a fully pre-configured Industrial Line solution for automated KH measurement and carbonate dosing — designed for professional aquaculture, research, and advanced aquarium installations where a standalone Doser or ProfiLux controller is already in place. Everything is pre-selected, matched, and pre-assembled — no sourcing decisions, no assembly required.
The system combines a KH Director IL and a Doser 3 EXT IL in a single IP54-rated Industrial Line enclosure. The KH Director IL continuously measures carbonate hardness and controls KH-changing liquid dosing via the Doser’s pump channels. As an extension unit, the Doser 3 EXT IL has no integrated controller and requires a controlling device connected via PAB: a Doser 3 SA IL, Doser SA IL, Doser Maxi SA IL, Doser 3 Maxi SA IL, or a ProfiLux controller (ProfiLux IL, ProfiLux 4, or ProfiLux 4e). The controlling device manages both the Doser 3 EXT IL and the KH Director IL via PAB.
The Doser 3 EXT IL features GHL’s PrecisionDrive technology — a custom-developed combination of 24V stepper motors and planetary gears, engineered and manufactured in-house — with 4 peristaltic pump channels, 0.1 mL resolution, and up to 250 micro doses per day. One 24V/2.5A power supply is included — the KH Director IL draws power from the Doser’s supply via its included splitter cable. The GHL Logo Frontpanel IL and blanking panels complete the front of the enclosure. Pre-assembly is included: all units are mounted, PAB cabling is wired, and the logo frontpanel is connected. The power supply is not connected during pre-assembly.
