Description
The Doser Maxi SA IL is the Industrial Line version of the GHL Doser 2.2 Maxi Stand Alone, housed in a 9HU aluminum slide-in housing designed for rack, cabinet, or the optional IP54-rated Industrial Line enclosure. It delivers the same proven technology and features as its standard counterpart in a form factor built for professional environments.
The Doser Maxi SA IL features 2 high-flow GHL PP2 peristaltic pumps driven by precision 24V stepper motors, delivering up to approximately 320 ml/min — ideal for automatic water changes, level control, and larger-volume dosing. Despite the high flow rate, micro doses as small as 0.1 mL remain possible. Each pump can deliver up to 150 automatically distributed micro doses per day or operate on up to 8 individually programmable dosing times. Continuous-run mode is also available, for example for operating reactors.
As a Stand Alone unit, the Doser Maxi SA IL includes integrated control electronics with WiFi and USB connectivity. Configuration and daily operation are handled via the GHL Connect app, myGHL cloud platform, the integrated web interface, or GHL Control Center PC software. Built-in features include refill/auto top-off, level indication with alarm, and support for temperature sensors, level sensors, and GHL Magnetic Stirrers.
Additional dosing capacity can be added via PAB (ProfiLux Aquatic Bus) by connecting Doser EXT IL and/or Doser Maxi EXT IL units, for a maximum of 16 pumps in one system.
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.
