SCANVENT’s valves are the only equipment needed to have an optimized VOC Management Plan on hand,
and so without any extra cost for new buildings, while reducing maintenance costs dramatically.
By-pass pressure valve type BP—VOCON
VOCON valve - In-line automatic weight-loaded pressure valve for mast riser systems.
In-line valve type TG—VOCON
In-line valve type TG for VOCON procedure designed to effectively reduce VOC loss. Comes in
hydraulic, electrical or magnet operated versions.
Is a VOCON mast riser system needed?
We would of course appreciate to sell as much equipment as possible. However, a VOCON mast riser
system serves to reduce the affect of standard p/v valves yielding 50% or more blow-down (difference
between opening and re-setting pressure). This is not a relevant concern when SCANVENT valves are
installed; these have no blow-down when thermal venting takes place. To put it differently, a VOCON
mast riser system will reduce the operative pressure, thus, increase the VOC loss compared to simply
leaving the SCANVENT high velocity valves with the dual nozzle system to take care of thermal venting
during voyage. Therefore, in conclusion, a VOCON mast riser system would seem overkill when in
combination with SCANVENT dual nozzle valves, but quite necessary if standard p/v valves are used.
Again, this goes to show that the SCANVENT dual nozzle system brings yet another saving to owner and yard.
