Rotex Ultra Series Models

Three Sizes with Automatic Plating Control

Overview

The Rotex Ultra Series silver recovery units are available in 3 sizes. All three are intended for use for either batch or continuous - flow operation. They are designed to electrolytically remove dissolved silver from thiosulfate solutions - both sodium thiosulfate as well as ammonia thiosulfate - common to photographic fixer baths such as: X-ray (radiographic), Graphics Arts films including 'Lith', Cinemagraphic (cine or movie), Typesetting papers, Color films such as C-41, Microfilm, Black & White films and papers

Rotex Ultra Units are not intended to remove silver from solutions containing developers or bleaches such as found in E-6 color slide fix, dichromate found in full reversal microfilm or color print paper chemistries RA4, R3 or EP-2

Three Sizes Available

  • Ultra 4 - 0.5 Troy Ounces silver recovery per hour and a 21/2 gallon recovery tank
  • Ultra 12 - 1.5 Troy Ounces silver recovery per hour and a 5 gallon recovery tank
  • Ultra 24 - 3.0 Troy Ounces silver recovery per hour and a 9 gallon recovery tank

Features

  • Lost Cost
  • Lower Power Consumption
  • One Year Warranty
  • Compact, Space-Saving Size

 

Adjustable Plating Current
Rotex Ultra Series silver recovery units have a "state of the art" plating current control to adjust the plating in direct response to the concentration of silver in the fixer solution. As the silver is depleted from the solution, the plating current will gradually reduce to zero. When an increase of silver is detected the plating current will rise.

 

Rotating Cathode
Rotex Ultra silver recovery units feature a motor driven cathode to continuously renew the silver ion in the liquid contacting the cathode, all called the cathode "junction". Without agitation of the solution, the junction would be quickly depleted of its silver ions and undesirable chemical reactions would occur. The rotating cathode was pioneered, patented and became the basis of the name "Rotex".

 

Direct Drive
Rotex Ultra silver recovery units use direct-drive gear motors without belts, gears, drivers, bushings or other components which require service or replacement. The gear motor shaft is sealed so that fumes from the fixer do not enter the electrical enclosure.

 

Power Supply
The power supply features a center-tapped transformer that is wound for low impedance and cool, efficient operation. The plating current is rectified from AC (alternating current) to DC (direct current) by a full way center tap bridge rectifier, that works more efficiently (produces less heat) than any other type of rectifier. The full-wave center tap bridge rectifier is cooled by a fan that also draws fresh air into the power supply enclosure thus ensuring long life. An ammeter is featured to indicate the plating current in "Amperes" and a circuit breaker is provided for convenient protection - no fuses to replace ever!
