OG MINI

Mini Size of Oxygen Generator for Laboratory

OG MINI is a range of compact, silent and efficient high purity Nitrogen generators for laboratory analytical instruments & devices. Each generator is endowed with 4.5" touch screen HMI with integrated PLC to obtain a total control of the process and of the its functionalities, managing in supplying Oxygen at the exact purity, pressure and small flow. In additional, plug & play solutions with built-in oil-free and tank are available on request.

The technology that OG MINI utilizes is the PSA process (Pressure Swing Adsorption). It is the engine that drives the separation of oxygen from air, with a degree of purity over 93%. It is a purely physical process denominated adsorption. During the adsorption step, nitrogen is adsorbed at elevated pressure and oxygen is produced. During the regeneration step, nitrogen is desorbed via depressurization and the adsorbents are regenerated. In order to convert this batch process into a continuous process, OG MINI uses two adsorbent vessels. As one is adsorbing, the other is regenerating and vice versa.

Key Features
