What is it?
Distilling is about bringing the beer, wine, or alcohol in the boiler of your still to a boil. The gasses, thus produced, are processed by the column and then cooled back to liquid state. A coolant is needed for that; a coolant that - in the process of liquifying and cooling those gasses - becomes warm itself.
The iStill Cooling Tower helps cool the coolant. As such, it takes the strain of your chiller, limits the amount of water used in the distillery, and creates a more energy efficient total distillery operation. Less water and energy usage, and a greener, more environmental overall profile.
The iStill Cooling Tower processes both water and glycol, and any combination of water and glycol. The coolant, coming from your iStil, flows into the iStill Cooling Tower and trickles down while being cooled. The coolant gathers in the collection vessel at the bottom. The collection vessel comes with a ball-valve to which a pump or chiller can be connected. The now lower temperature coolant can be transferred (with or without additional chilling) back to your coolant reservoir.
What's innovative about it?
Its efficiency! The iStill Cooling Tower uses evaporation as a pre-chiller treatment. As a result it can bring 60 degrees Centigrade back to 45 degrees, at a processing rate of 10 to 15 liters per minute. Cooling a 7 hour production run only costs 1 kWh!
Size and price?
The unit is 2 meters high, runs on 230v single phase, and is equipped with our bigger Gardena quick-connects for easy coolant transfer. The legs can (and should) be bolted to the floor. The unit is perfect in combination with any iStill 500, 1000, 2000, or 5000. It also serves the iStill 100 and 200, even though the iStill Cooling Tower might be considered a bit "overkill" in those situations.
The iStill Cooling Tower costs EUR 7.000,- and can be ordered via the iStill Design Center, as part of your bigger iStill order. If you want to order the iStill Cooling Tower directly, please reach out to Esther@iStillmail.com.
