Ventilation cover

When filling up or making a delivery from a ground tank, the
ventilation pipe will allow it to breath. At the same time, the pipe makes the tank accessible for unwanted dirt and water.

Limiting the access of water and dirt in a ground tank decreases the risk of contamination and degradation of the product.

Water and unwanted particles
The ventilation cover, available in two sizes, DN50 (2”) and DN80 (3”), decreases:

• intrusion of rain into the tank
• intrusion of insects and larger particles into the
  tank due to the insect mesh.

For a top-of-the-line air filtering product (down to 3 microns)
that also dries all air going into the ground tank, take a look at
Torkel® by Wennstrom.

Environtment Safeguard
The ventilation cover is part of ”Environtment Safeguard”, our
system for increased safety and security at the filling, dipping
and ventilation point of fuel tanks.

Versions of the ventilation cover Item no.
Ventilation cover 2" ES1060L
Ventilation cover 3" ES1080L

 

 

Torkel™ - atmospheric protection for biodiesel

Renewable fuels
In order to decrease the carbon footprint the general use of renewable fuels is on the increase. To get a quick effect it is important that the fuel can be used in existing vehicles and for this reason the blending of renewable fuels with mineral oil products has increased.

Biodiesel
Biodiesel is a vegetable oil- or animal fat-based diesel fuel that is often used blended with petrodiesel. Biodiesel is, like ethanol, hygroscopic which can cause problems since water accelerates the growth of microbe colonies which can clog up filters.

Keep water out
One of the main challenges when it comes to storing biodiesel
is to keep water out of the tank. There are a number of openings that have to be taken into consideration. The dip tube is one of these which can be dealt with using our Outlock.

Ventilation pipe
Another potential source of water is the ventilation pipe. Every time product is dispensed from the tank, air is sucked in via the ventilation pipe. During periods of high humidity this also means that water is introduced into the tank and since biodiesel is hygroscopic there is a risk that the water will mix with diesel. This will accelerate bacterial growth that can result in expensive consequences.

Naturally closed
With Torkel™ the tank will be naturally closed. This will stop the normal “passive” exchange of air due to temperature changes. This air with water content may otherwise condense on the inside of the ventilation pipes and tank, collecting and trickling down into the diesel.

Dry air
By leading air that is sucked into the tank during normal refueling at the dispenser through a filter, Torkel™ will effectively dry the air that must be allowed into the tank. When the tank is being filled up the air pushed out will also help take moisture from the filter thereby prolonging its’ lifespan.

Clean Air
Another important function of Torkel™ is to reduce the amount of particles that are drawn into the tank during normal “breathing”. Anything larger than 3μm will be stopped. This gives cleaner fuel which in its turn extends the lifespan of the engines running on the fuel. It also means cleaner tanks decreasing the need for maintenance.
