The ethanol vapor passes through our patent-pending Diffusion Condenser and converts into liquid ethanol. The diffusion of the bubbles quickly dissipates heat into the liquid ethanol and condenses the ethanol vapor. The excess heat is then removed from the liquid ethanol via a plate exchanger to water, which is being circulated through the outdoor radiator. The radiator has a fan which efficiently transfers the heat from the water stream to the atmosphere. FUN FACT: you can get an extra radiator and use the excess heat from your system to heat your lab in the winter!
