Advanced clean agent line that originated exclusively in the aerospace industry and is now available for commercial applications. HT agent combines extremely low GWP and very low ODP with reliable suppression performance. 7-day atmospheric lifespan minimizes environmental impact far beyond most alternatives.


Non-rechargeable design (12-year service life). Anodized aluminum cylinders on most models (Model 551 uses steel). Models 549 and 551 include a hose for hard-to-reach areas.


Primary industries served: healthcare facilities, clean manufacturing, data processing centers, and museums. No clean-up or down time — the agent leaves no residue and requires no post-discharge remediation.
