Gas Freeing Cover
The Pres-Vac Gas Freeing Cover is designed to ensure safe and controlled gas freeing operations on oil and chemical tankers. The solution supports both portable blower operations and controlled venting during voyage, while maintaining full focus on crew safety and regulatory
compliance.
Portable Blower Solution
The portable blower is connected to the tank opening and driven by a water turbine. The turbine creates a strong airflow, forcing toxic or flammable vapours safely out of the tank.
This solution ensures:
- Efficient tank ventilation
- Reduced exposure of crew to hazardous vapours
- Controlled and reliable gas dispersion
Sampling / Gas Freeing Cover
The sampling cover allows controlled and explosion-safe gas freeing during voyage.
When opened, air can escape from the tank while a built-in wire mesh flame screen prevents ignition sources from entering the tank. This ensures compliance with applicable safety standards for tanker venting equipment.
