- Weather tight seal even when not pressurised
- Lowest profile design, consequently, there is typically no change in the overall height of tanker
- Manufactured from durable machined billet (Type 6061) aluminum for precision and the highest operating pressure ratings
- Food grade seals available
- Lid slides open supported by a HDPE replaceable slide pivoted on non-load bearing hinge pin, thus reducing wear
- A vacuum is applied to the seal when it is deflated, retracting the seal into the lid. This minimises scuffing and wear and extends seal life and reliability
- DOT approved pneumatic fittings
- The scraper and purge functions minimize buildup, reduce maintenance and extend seal life and reliability
- Multiple cover operation from one Control Box, up to 4 hatches on a truck unit can be individually controlled
- Standard operating pressure of 2 bar with units capable of operating at 2.5 bars for rail tankers and specific applications
- Light-weight aluminum construction and bolt on design means you require minimal structural modifications to your tankers
- Flip over lid for ease of maintenance and replacement of seal
- Easy installation to new tankers or can easily be retrofitted to existing vehicle. Installation only takes 3 to 4 man hours using basic tools and components supplied
- Bundled PVC sheathed airlines for ease of installation, providing abrasion and UV protection. Extremely low consumption of compressed air
- Safety Feature – If tanker is opened when pressurized, the seal will deflate and it will be very noisy and dusty. However, until the tanker pressure drops below approx. 5 PSI, and it is safe to open the hatch, the pneumatic cylinder is unable to open the hatch fully
- Optional dust control flange gasket
- Cylinder is not energized when seal is inflated, thereby extending cylinder life
