PRONAL OPAP Permanently Installed Inflatable Anti-Pollution Pipe Plug (OPAP 150–1000)
French PRONAL OPAP (Pollu-Plug) is permanently installed at the pipe crown (< 5% obstruction when deflated). Upon emergency trigger from an autonomous ground control cabinet (manual, punch button, fire alarm, or GSM), it inflates rapidly to isolate industrial drain networks and retain hazardous chemical spills or firewater runoff (Ø100–1000 mm).
Quick Selection & Compliance Summary (TL;DR): PRONAL OPAP is engineered for permanent installation at storm drain outfalls and plant discharge points. Remains deflated at the pipe crown with zero interference to regular rainfall discharge (< 5% obstruction). Rapidly seals pipelines up to Ø1,000 mm from the ground level without confined-space entry, assisting facilities in implementing accidental spill emergency response and firewater containment.

Frequently Asked Questions (FAQ)
Q: Does PRONAL OPAP obstruct normal drainage flow when deflated?
No. PRONAL OPAP is permanently mounted at the crown (top) of the drainage pipe. When deflated during normal operation, it remains flat against the pipe crown with less than 5% cross-sectional obstruction, allowing stormwater and normal plant effluent to flow freely.
Q: How is PRONAL OPAP activated and reset during an emergency?
OPAP is connected to an autonomous ground-level pneumatic control cabinet (with an integrated compressed gas cylinder and pressure regulation system). It can be triggered via manual valve, emergency punch button, wired telecontrol/fire alarm interlock, or GSM mobile telecontrol. After the contaminated liquid is pumped out, deflation and reset are performed directly from the control cabinet without personnel entering the confined pipe space.
Q: How does PRONAL OPAP differ from portable plugs like PIG Multi-Flex?
PRONAL OPAP (OPAP 150-1000) is permanently installed at drainage outfalls or main storm lines for immediate containment from a ground control station, whereas PIG Multi-Flex is a portable, high-expansion plug carried by emergency response teams for temporary spot isolation.
