Why use distillation column insulation?

Reflux Precision: A distillation column insulation maintains a stable temperature gradient, enhancing reflux separation and producing clearer, higher-proof spirits.

Efficiency Boost: Reduce energy consumption by minimising heat loss, allowing faster heat-up and smoother runs.

Safety First: Prevent burns from the hot column surface. The column runs at 79 > 82°C (174.2 > 179.6°F) and the insulation acts as a barrier thus stopping you from getting burnt.

insulation material for distillation column Still:

Closed-cell foam: Versatile, easy to fit, and withstand high temperatures.

Pool noodles: Budget-friendly option for smaller columns.

Rockwool: Excellent thermal resistance for demanding setups.

Prefab pipe wraps: Convenient and readily available, but less efficient.

Don’t Forget the Kettle:

Blanket insulation: Easily removable for cleaning and inspection.

Jacketing: Permanent option for maximum efficiency and control.

Pro Tips for Distillation Column Insulation:

Leave inspection points accessible: Avoid covering critical connections.

Seal against the elements: If your column is outside or in a draft the elements (wind) will affect it and cause temperature swings. If the balance of the column is affected in any way it will affect the purity and ABV.

Consider custom solutions: Tailor insulation to your specific column diameter and packing.

Invest in Quality, Reap the Rewards:

Smoother, purer spirits: Enjoy consistent, high-quality results.

Reduced distillation time: Save time and energy with faster runs.

Enhanced safety: Minimize burn risks for a safer distilling experience.

Insulate your still is a must

We discover using an insulated column saves time and money in the end. In short, it is quicker than an uninsulated column. We highly recommend using distillation column insulation on your still to keep the temperature of the reflux column on point.
