Industrial cooling used to rely solely on water. As technology advanced, so did cooling methods and options. Now you have no less than three choices for industrial cooling, each which have their own benefits.
Dry ice is one of the coldest substances on the planet. Made from solidified CO2, which only freezes at temperatures so cold they have to be reproduced in a lab, anything that you need cooled quickly or kept really cold to avoid an explosion can be accomplished using dry ice. As an added benefit, dry ice is shipped within hours of ordering it, since it evaporates over a short period of time when exposed to the air. You can get your dry ice in less than a day and it will keep things cold or cool for at least three days, depending on the size of the block of dry ice.
Liquid nitrogen, when completely contained within an outer rotary drum, can continuously spin and cool any other drum of materials tucked within the outer rotary drum. It is not the safest material with which to work, but it will definitely cool as well as, if not better than, dry ice. As long as the liquid nitrogen is never exposed to the air either, it will not dissipate like dry ice.
Refrigerated Forced Air
Refrigerated forced air is similar to air conditioned air. It is the same cooling process, except that on the industrial level the air is colder and it is blasted onto a hot surface or hot material to get a desired result. One such example is the blast of refrigerated air blasted onto molten metal. It causes the metal to cool much quicker than water and without all of the negative environmental side effects of using water to cool the metal.
Setting up Equipment That Can Manage These Cooling Forces
Your next step is to select the material you want to try and then set up the equipment that can manage the cooling force(s) you selected. Depending on what you are trying to cool and how quickly you want to cool it, you may be cornered into selecting one type of cooling method over another. Be sure to consult with your mechanical and chemical engineers before you start buying cooling equipment for the plant. That way, you can be sure of exactly the right equipment needed for the daily processes in the plant.Share
