Product Description


As it leaves the digester, raw Biogas is saturated with water and must be dried before it can be used.

It is therefore cooled to 41°F (5°C) in the VALOGAZ unit, which separates and eliminates the liquid fraction contained in Biogas. The unit is dimensioned in a way that allows cooling the maximum flow rate of gas in even the toughest conditions.

For this, PRODEVAL employs the use of smooth, 316L stainless steel tubes, alongside with two chillers to handle any variations in temperature.

The gas is then moved onto the next stage, VALOPACK, via the blower.

  • A wide range covering needs from 59 to 1558 scfm (94 to 2500 Nm3/h)
  • Quality equipment designed for Biogas applications in difficult environments
  • Redundancy of the refrigeration unit for maximum coverage of the operating range
  • Smooth tubes enable the maximum flow rate of gas to be cooled
