Chiyoda Seiki DSS-40/-60/-100 Dry Safety Device – Gas Collecting Device – For Piping Installation – Large Flow Type
Made in Japan
Manufacturer: Chiyoda Seiki
Model: DSS-40/-60/-100
Feature
Space saving: Lightweight and compact compared to conventional water-sealed safety devices, and can be installed freely.
Welding and cutting quality: Low pressure loss and no moisture content in flammable gases prevent quality deterioration in welding and cutting.
Reliable backfire prevention: When activated, the flame is shut off and extinguished without letting the flame out (Shinwa type special flame extinguishing element, registered as a utility model).
Even if the PAT flame retardant element becomes clogged, its ability to prevent backfire will not deteriorate. Backfires can also be prevented even if a gas mixture forms on the primary side (upstream side).
Labor-saving maintenance: Voluntary visual inspection every year and periodic performance inspection every three years are all that is required.
