Doser 3 Maxi EXT IL (9HU)

Doser 3 Maxi EXT IL slide-in unit (9HU) – the GHL Doser 3 Maxi Extension in an aluminum Industrial Line housing. 2 high-flow peristaltic pumps with SilentDrive technology, up to ~350 ml/min, 0.1 mL resolution, 250 micro doses per day. Connects via PAB to a Doser SA IL, Doser Maxi SA IL, or ProfiLux controller. Power supply not included.

The Doser 3 Maxi EXT IL is the Industrial Line version of the GHL Doser 3 Maxi Extension, housed in a 9HU aluminum slide-in housing designed for the IP54-rated Industrial Line enclosure. The unit can also be installed in custom enclosures or cabinets. It delivers the same proven technology and features as its standard counterpart in a form factor built for professional environments.

As an Extension unit, the Doser 3 Maxi EXT IL does not include its own control electronics. It connects via PAB (ProfiLux Aquatic Bus) to a Doser 3 Maxi SA IL, Doser 3 SA IL, Doser SA IL, Doser Maxi SA IL, or a ProfiLux controller (ProfiLux IL, ProfiLux 4, or ProfiLux 4e), which manages all dosing settings.

The 2 high-flow peristaltic pumps feature GHL’s SilentDrive technology — advanced motor driver electronics paired with precision 24V stepper motors for powerful yet exceptionally quiet operation. Each pump delivers up to approximately 350 ml/min with micro doses as small as 0.1 mL. Every pump can distribute up to 250 automatically spread micro doses per day or operate on up to 24 individually programmable dosing times. Continuous-run mode is also available, for example for operating reactors.

Multiple Doser 3 Maxi EXT IL, Doser 3 EXT IL, Doser EXT IL, and Doser Maxi EXT IL units can be combined via PAB for a maximum of 16 pumps per SA host or up to 32 pumps when connected to a ProfiLux controller. All GHL Doser generations (2.x and 3, standard and Maxi) are fully cross-compatible.

An optional GHL Logo Frontpanel IL (5HU) can be connected to the unit’s RGB logo port for visual system status indication.

Note: Power supply (24V) is not included and must be ordered separately. This allows the same unit to be deployed worldwide without country-specific variants.
