Controlling the water outlet temperature is the primary user control in the T500 Distillation System process.
Tests done on the T500 indicated that the ideal water outlet temperature range is between 55°C and 65°C (131°F to 150°F). It can be reduced to as low as 50°C (122°F), but this will slow the rate of alcohol production. Alternatively, the outlet temperature can be increased to a maximum of 65°C (150°F), which will speed up the alcohol flow but result in slightly lower strength and purity.
As a rule, running the still between 60-65°C (140-150°F) will produce alcohol faster but at a slightly lower strength and quality, while running the still between 55-60°C (131-140°F) will provide you with optimum quality but it will take a bit longer.
The higher the flow rate, the cooler the condenser and the slower the distillate will flow. The lower the flow rate, the hotter the condenser and the faster the distillate will flow.
