CONVEX
Evaporators heated by atmospheric air

Application:

CONVEX HD:
  • cylinder filling plants for industrial gases 100 to 420 bar
  • high pressure process supplies
CONVEX ND:
  • cryogenic devices
  • medium-pressure supplies, 10 to 100 bar with high throughputs
  • ultra-pure gas supplies

Design features:

  • vertical stainless steel pipe registers with large surfaces aluminium fins / galvanised steel or aluminium support frame,
  • arrangement of pipe registers like walls of a vertical chest, open at top and bottom facilitates stable convection along the evaporator walls, substantially independent from wind velocity and direction

Operating / performance features:

  • small set-up space required
  • performance largely independent of atmospheric effects
  • constant performance during continuous operation
  • option for outlet temperature adjustment under summertime operating conditions
