Automatically switches from Exhaust to Fresh DI Bank
AQUASWITCH™ Fully Automatic DI Bank Switching System
What it Does:
The AQUASWITCH™ is a special purpose dedicated computer which automatically "changes out" an exhausted DI bank for a fresh, stand-by bank. LEDs continually give the condition of both banks. An alarm output is activated as each bank is depleted.
How it Works:
When the monitor/controller senses poor quality water merely because the DI system has been shut down temporarily, the AQUASWITCH purges the "on-stream" bank until water quality recovers. If the DI bed is exhausted, however, water quality will not improve sufficiently after purging. The AQUASWITCH will then automatically take the exhausted bed out of service and switch over to the stand-by bank. The fresh bank is purged until the desired quality level is reached; it then goes into service.
The purge cycle is controlled by a timer which is easily adjustable for periods from 1-10 minutes. This feature allows the system to be tailored to the requirements of each application, and ensures banks are not switched or shut down prematurely. A "manual change over" button can be depressed to switch banks at any time.
The AQUASWITCH features advanced circuitry, including three solid state (not mechanical) relays to reliably operate the solenoid valves. Three or four solenoid valves suitable for ultrapure water (not supplied) are needed to make a complete AQUASWITCH system.
The standard AQUASWITCH I does not monitor water quality itself, but may be used with any reliable Resistivity or Conductivity monitor/ controller such as the Myron L 750 Series II. They are available in several ranges.

How to order:
1) Choose either whether you want Resistivity or Conductivity
See Range Selection Guide
2) Options & Accessories
3) Valves not supplied. The AQUASWITCH series is compatible with quality solenoid valves of any voltage. Valves #1, 2, and 3 on diagram should be normally closed. Valve #4 (to process) should be normally open.
Warranty
All Myron L AQUASWITCH controllers and sensors have a two-year warranty. If any AQUASWITCH or sensor fails to function normally, return it to the factory prepaid. If, in the opinion of the factory, failure was due to materials, or workmanship, repair or replacement will be made without charge. A reasonable service charge will be made for diagnosis or repairs due to normal wear, abuse or tampering. Warranty is limited to
the repair or replacement of the Myron L AQUASWITCH or sensor only. Myron L Company assumes no other responsibility or liability.
