Operated manually or triggered by means of automatic sensors draintector isolates part or the whole of a site ensuring the retention of spillages or fire-fighting run-off on site.

Product Overview

Drain closure systems provide instant security against the polluting of controlled waters.

Draintector™ drain isolation system rapidly seals drains, stopping pollution of the watercourse at the flick of a switch.
With simple, low-cost installation requiring no major civil works, Draintector™ is far more cost effective than mechanical gate and penstock valves and is installed in a fraction of the time with minimal disruption to business

Draintector™ can be used as a preventative measure to seal drains at time of high risk including deliveries and during site maintenance. It can also be used in an emergency situation, in the event of a spill or fire, to rapidly block the drain preventing hazardous liquids and firewater runoff entering controlled waters.

The system comprises a control panel located above ground that operates a closure system installed within the site drain system without affecting the flow in normal conditions. When activated, the closure system seals the drain
ensuring no pollutants or firewater runoff pass through.
