The Challenge 1
Xianke Co, Shenzhen, China, is a leading manufacturer of semiconductor equipment and components. They de-wax parts using superheated steam at 0.78 bar (g) and 180 °C.
Low-temperature steam has very high latent energy content, but in a traditional heat exchanger the pressure drop is too high to achieve a satisfactory flow through the heat exchanger.
With the Airec design, even the energy in low-pressure steam can be used to heat water.
After de-waxing, the low-pressure exhaust steam is discharged through one Airec Cross 30-140/C.
The steam goes through the low-pressure side B while the water, which is heated in the heat exchanger, goes through the side A channels.
The Airec heat exchanger’s high efficiency and low pressure drop enable all the energy from the condensing process to be used, with all the low-pressure exhaust steam condensed to water.
