In cosmetics, the most common use of acetone is in nail polish remover. Acetone is a colorless, flammable liquid that evaporates easily. It is an organic compound because carbon atoms are present in acetone's chemical formula, which is (CH3)2O.
Swenson thermal vapor recompression (TVR) evaporators use a thermocompressor to reduce the steam required per pound of evaporation. To reduce energy consumption, water vapor from an evaporator is entrained and compressed with high pressure steam in a thermocompressor so it can be condensed in the evaporator heat exchanger. The resultant pressure is intermediate to that of the motive steam and the water vapor.
Many models, such as the Hessaire MC17M 800 CFM Evaporative Coolers or the Portacool Cyclone 110 Portable Evaporative Cooler, are lightweight and even easier to transport. Oftentimes, however, lightweight swamp coolers are better suited for personal cooling, operating much like a personal heater.
