Hydrogen Applications sprayed from the top with water . In co-current flow , air is sucked in through the bundle by means of the fan next to the bundle . While water and air flow through the tube bundle , the water evaporates , causing the water film on the tubes to cool down . Below the bundle , the water drops in the water basin , from where it is pumped back to the top to be sprayed over the tube bundle . The air turns to the second part of the tower and flows upwards , through the fan . The air velocities in the turning section and in the second part of the tower are designed in such a way that any droplets will drop back into the water basin . Because air and water flow downwards together ( cocurrent flow ), the air helps to spread water evenly over the entire tube surface . There will be no dry spots , resulting in less scaling and fouling .
The Tundracel is therefore suitable for poor water qualities , such as :
• Blowdown from cooling towers and boilers
• Waste streams from demineralizers , scrubbers , etc .
• Plant effluent wastewater
• Brackish water
Conclusion Thermal management in green hydrogen plants can be divided into two extremes : dry cooling and wet cooling . In general , it can be said that dry cooling is characterised by higher power consumption and larger footprint than wet cooling towers but of course no water consumption .

However , between these two extremes , there is a whole world of intermediate , or hybrid solutions . Fogging systems and adiabatic pads systems for Air Fin Coolers and the Tundracel closed-loop cooling tower are just some of them . The best choice highly depends on the project requirements , such as availability of water , water quality , and site conditions ( dusty and / or windy ). www . heat-exchanger-world . com Heat Exchanger World November 2022
