Features of COLENTA NDT Processors
|
The COLENTA intermediate rinse bath (prewash) system with squeege roller between fixer bath and main wash tank, offers a double wash or
cascade wash facility, whereby the prewash takes the main part of the silver containing fixer carryover, suitable for separate collection
or connection to an inline treatment unit - this in view of aggravated environmental regulations.
For COLENTA’s INDX-processors a delayed wash water supply (especially an issue when programmed for extended processing cycles) is a standard
feature. The microprocessor controller monitors the positions of the films while traveling through the processor and supplies water to the
wash section when a film enters this section. As an additional option, amount of washwater supplied can be linked to the size (m²) of film
entering the wash section - this again in view to the stricter environmental rules forthcoming.
* The COLENTA roller transport system does not use spring tensioned opposed rollers or metal guides, which can cause pressure marks
and scratches on the emulsion. Any length of roll film can be processed. All transport rollers are below solution level, eliminating
crystallization and dirt build-up on the roller surface that could cause damage to the emulsion or dirt related quality problems. The
submerged rollers are designed to balance in solution consequently reducing pressure and wear on bearings - virtually eliminating
maintenance costs and extending the life of the racks.
* The COLENTA transport racks are individually identified and fitted with maintenance free inline precision gearing systems to
give trouble free operation. - We know, how much our competitors are suffering by their worm gear driven transport racks.

* The COLENTA intermediate rinse baths system with squeegee rollers gives consistently clean film/paper with minimal carryover of
chemistry into the next solution, and savings in the replenishment costs and daily cleaning time. Crossover rollers located above liquid
level are designed for easy removal and cleaning.

* COLENTA’s programmable, multi channel memory microprocessor controllers, used in the all our GA-Film Processors -
allowing the operator to preset exact processing datas - are activating and monitoring all functions of the processors.
All indications are given on the digital display on the CPU board of the microprocessor, where all error indications are
also shown. For error indications and film feed release an additional audible signal is available.
Functions like automatic standby, water saver, antioxidation and anticrystallization cycle, automatic start/stop function,
are state of the art for COLENTA processing equipment.

* We replenish exactly according to the amount of square inches of film surface fed into the processor - we use pulsed
infrared sensors (not exposing IR-material of course!) for our replenishment system, instead of mechanical replenishment switches.
* COLENTA’s slim roller transport rack design results in low volume tank processors - already a big move forward to forthcoming
new processing technologies - LTTV (Low Thin Tank Volume) technology.Also due to the slim COLENTA rack design, a small surface
of chemistry is exposed to the air, reducing air oxidation. Both advantages - less air oxidation and easy, quick complete turnover
of the whole content of the low volume COLENTA processor tanks by normal (or even reduced) replenishment rates - are leading to constant
high quality processing results.
