NEW from GHL A new addition to the GHL product line The popular GHL Doser 2.1 just added a new member to the family. Meet GHL Doser Maxi. As with all GHL products, the GHL Doser Maxi is built on the proven framework that earned GHL its global recognition for ultimate reliability and performance. The Doser Maxi is fitted with two brushless stepper motors that are rated to move up to 350ml per minute! Perfect for AWC and Continuous-use Tired of lugging those buckets around? Take the work out of manual water changes and let the GHL Doser Maxi do it for you. Conveniently schedule automatic water changes or trigger them as-needed. Need to continuously do larger water changes? No problem. Our brushless stepper motors are built and ready to withstand larger volume water changes. As with other peristaltic pumps which require a cool-down period, the Doser Maxi’s stepper motors can be run continuously for longer periods without needing a cooling period. For example, you can transport water for a water change at one time without needing a cooling period. Pumps are suitable for moving approximately 16,000 Liters (4,226 gal) of water. No controller required! We are firm believers in giving reefers the option to use our dosers without having to go out and buy a separate controller just to run it. For that reason, the GHL Doser Maxi will be offered as a Standalone or Slave model. The Maxi Standalone doser is perfect for those who do not own a ProfiLux 3, ProfiLux 4, Doser 2.1 SA or Doser 2 SA. The Maxi Slave doser seamlessly ties into an existing Doser 2.0 / 2.1 SA or ProfiLux 3 / 4 eco-system. Backwards compatibility Have a ProfiLux 3 or Doser 2.0 SA? Don't worry we didn't forget about you! ProfiLux 3 and Doser 2.0 SA owners can also add one or several Maxi dosers to their system and benefit from all that the product has to offer. Product flexibility like no other Already have a Doser 2.1 SA or Slave? No problem! The GHL Doser 2.1 and Maxi can be combined, Standalone and Slave in any combination. Same rules apply to those who have a ProfiLux 3 or 4 controller; all slave pumps can be controlled. Standalone Maxi dosers can easily be converted to operate as a slave unit.
