Claind Laboratory Generators

Nitrogen Generator


The DOMINUS NL uses high-quality CMS resulting from 40 years of research and testing in collaboration with specialists in the field. An automated filling system ensures higher density and better generator reliability than a conventional system. Included Eco mode minimizes air and energy consumption thanks to automatic process time adjustment and proportional phase modulation relative to the nitrogen withdrawn. The machine will go into automatic stand-by mode if the nitrogen flow is greater than the flow drawn in. The process is manually adjustable in order to maintain the desired degree of purity. The DOMINUS NL provides continuous nitrogen availability without the need for supervision or user activity with the benefit of pre-set operating programs. Includes a nitrogen shut-off valve allowing for flow management according to purity and pressure levels, as well as symbiotic use with other supply sources.

The DOMINUS NL features a long lasting, high sensitivity oxygen analyzer and is equipped with a state-of-the-art electronic touch screen display to view operating parameters and maintenance alerts. It also comes with access to the Claind4You portal, allowing for remote, secure, and independent control of the unit. Flexible communication with external systems using MODBUS, MQTT, and https protocols, allows for full integration and control.
