In the AGFA NDT-S Eco developing machine, a cascade fixation system is used, due to which the amount of silver in water is 15 to 25 times lower than in a conventional washing machine.
The principle of cascade fixation is very simple in its essence: the exposed film is first processed in the developer, and then washed in the intermediate rinse tank. The intermediate rinsing system prevents the transfer of the developer to the fixative tanks and thus prevents the appearance of defects from the developer on the film.
Then the film is fixed in the first fixing tank and rinsed in the second. Since the replenishment with fixative is made in the second fixative tank, the concentration of silver in it remains very low; Consequently, the transfer of silver to the wash tank is reduced to 40 mg / m2. In addition, the exact replenishment of fixatives in such a system implies a low consumption of chemical reagents.
AGFA NDT-S Eco can be operated in a 5- or 8-minute cycle. In both cases, the capacity of NDT-S Eco is sufficient to satisfy consumers with high performance requirements.
The AGFA NDT-S Eco processing machine is equipped with triple drain valves, which allows for easy draining of photoreactive chemicals and cleaning chemicals to the appropriate tank.
The pallet for receiving the film in the machine AGFA NDT-S Eco can easily be adapted to work with format films of welding formats (from 6 × 12 cm and above), and roll films up to 5 m in length. The processed film will always be collected on a pallet accordingly.
