VR1 adaptor with flame arrester

Vapour recovery stage 1
The VOC Directive 94/63 1994 states that vapour recovery stage 1 is required for ­petrol within the EU. One part of stage 1 is to collect the vapour from the service station into the road tanker during delivery. The VR1 adaptor is the connection point of the vapour recovery hose from the road tanker.
The Wennstrom VR1 adaptor comes with or without a flame arrester. The choice depends on local requirements and on the total risk analysis for the storage tank.

Flame arrester
Ignitions sources, such as sparks caused by electrostatic discharge or lightning or mechanical knocks, in potentially explosive atmospheres can have disastrous effects. An investment in a flame arrester is a safeguard against such an accident.

Flame ­arresters in accordance with EN12874 are normally required for petrol and E85 installations.

Simplified installation
The design of the unit and integration of the deflagration flame arrester simplifies the entire installation and maintenance. Its’ compact size (only 157mm long) makes the adaptor ideal at new installations and suitable even when retrofitting existing ones. The special earthing point mini­mizes the risk for sparks due to potential differences

Total risk analysis
In combination with a flame arrester in the ventilation pipe such ES4X6 – End of Line flame arrester with integrated p/v valve, and the HSE Interlock valve at the filling point, the storage tank will be effectively safeguarded against probable risks for explosion.
