Ambient Air Heat Exchangers
Application
CONVEX HD / HHD
- filling stations for industrial gases up to 500 bar
- high-pressure process supplies up to 800 bar
CONVEX ND
- supply at low to medium pressure (10 to 100 bar) with high throughput
- supply of ultra-high purity gas
Design Features
- small foot print
- fin tube registers mounted on a galvanised steel frame form a box-shaped
tower with four „finned“ side walls that is open at the top and at the bottom,
facilitating stable convection on the inside that is mostly unaffected by wind - the cooling registers consist of stainless steel pipes inside welded
aluminium fin sections that feature large surface areas
Performance Features
- performance is largely unaffected by the elements
- steady performance during continuous operation
- permits outlet temperature to be adjusted in hot weather conditions
