Description
The Doser 3 SA IL is the Industrial Line version of the GHL Doser 3 Stand Alone, housed in an 8HU 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 advanced technology and features as its standard counterpart in a form factor built for professional environments.
At the heart of the Doser 3 are GHL’s new PrecisionDrive pumps — a custom-developed combination of 24V stepper motors and planetary gears, engineered and manufactured in-house. The result is outstanding dosing accuracy, quiet operation, and excellent long-term stability. Each of the 4 peristaltic pumps delivers up to approximately 80 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. Front-panel push buttons allow quick manual dosing or tube priming at any time.
The integrated Stand Alone controller provides WiFi, LAN, and USB connectivity, including OTA firmware updates over WiFi or LAN. Level sensor ports enable fully autonomous Auto Top-Off and Automatic Water Changes directly from the Doser. A temperature sensor port allows continuous monitoring of water temperature. 4 Magnetic Stirrer ports allow mixing of sensitive or concentrated dosing solutions before dispensing.
Additional dosing capacity can be added via PAB (ProfiLux Aquatic Bus) by connecting Doser 3 EXT IL, Doser EXT IL, Doser Maxi EXT IL, or Doser 3 Maxi EXT IL units, for a maximum of 16 pumps in one system. All GHL Doser generations (2.x and 3, standard and Maxi) are fully cross-compatible. The Doser 3 SA IL also serves as the required host for KH Director IL and ION Director IL units, which connect their tubing to the Doser’s pump heads.
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.
