Pneumofore have finished evaluation of the A35 air compressor in terms of vibration, pressure, absorbed power and temperature as part of the on-going Atex certification process.

Dry running tests confirmed the CE Ex II 2 GD Ex-conformity of our rotary vane air-ends, which are used for compression of gas.

The infrared picture shows the temperature map during the start-up of the destructive dry running test, and the horizontal air-end is can be seen on the left.

The vacuum air-ends were certified Ex II 2 G c T3 (-29°C – +50°C) in 2012, and are currently successfully running in several hydrocarbons Vapor Recovery Units (VRUs), predominantly in Europe and Asia.
