Impression and Sanitizer Plus Series

The ITW (Impression) and ASPTW (Sanitizer Plus) Twin Series systems provide uninterrupted conditioned water, available 24 hours a day, seven days a week. This is made possible because when one tank becomes exhausted, the system automatically switches to the system's reserve tank. An added benefit of the system's flexibility is that each of its tanks can utilize 100% of their capacity! This eliminates the waste of unused capacity, an occurrence routinely experienced when single tank systems are used.

The ITW and ASPTW Series valves achieve optimum performance using a single piston and corrosion-resistant spacers and seals. This piston design offers long-term operation with minimal maintenance. Tight tolerances and precision machining optimize performance, even in challenging environments.
