ULTRA A: CONTINUOUS FLOW-THROUGH OPERATION
The Rotex Ultra-A series may be used to remove up to 99% of the silver in the fixer overflowing from a film or paper processor by connectingits inlet fitting directly to the processor fixer overflow. The Ultra A should be connected to operate anytime the processor is operated. A timer can be connected between the Ultra A and its power source if the user intends to operate during selected hours. The outlet or 'Overflow' fitting on the Rotex Ultra A is connected to a steel wool cartridge to trap residual silver as required by most state and local codes.
On occasion, a processor may see varying usage rates with peak periods of use followed by idle periods. The peak period may overflow more silver than the Ultra A can recover due to the high flow rate. In such an installation, a Rotex Autometer may be added between the processor and a standard non-automatic Ultra. The Autometer will precisely meter a continuous flow rate into the Ultra, and, during an idle period when no flow is available from the processor, the Autometer simply switches the Ultra off and waits until more fixer leaves the processor.
The Rotex Autometer may also be used to collect fixer from more than one processor overlow for metering through a single Ultra unit. This would eliminate the need for an additional Ultra and its 'tailing' steel wool canister.
