Heating orHeat transfer from steam to air
The problem 
In demanding dryer applications the heat exchanger must heat a large air-flow to a high temperature close to the condensation temperature for the steam. This problem can be solved either with a large traditional steam coil and high pressure steam, or the compact high efficiency AirCross 21 that even performs perfectly at a considerably lower steam pressure.
The solution - AirCross 21, the cost and space saver for the designer
Getinge Disinfection AB, Sweden, is the world leading producer of washers and disinfectors for infection control systems within the health care industry and research laboratories. The new larger Cart Washer Disinfector-9100 for bulky goods includes a dryer function which requires a steam-to-air heat exchanger. The task is to heat 750 Nm3/h from 40 to 130°C (104 to 266°F) and the demands are for high efficiency, compact design and a low pressure drop.
