  • Dual Filter facility with micron ratings down to 0.2
  • A variable flow rate of between 0 and 10,000 litres per hour.
  • A two stage vacuum facility offering a 200m3/hr vacuum pump and a 1400m3/hour vacuum booster, a 2nd pair of Vacuum/Booster pumps to allow multiple units to be placed under vacuum simultaneously, offering 0.05mb
  • A heating facility in four stages offering a total of 160 kW.
  • In-line moisture meters to detect moisture from source & prior to transformer
  • Fully automated, with air operated valves, full interlock will close valves automatically.
