Cooling Towers for Distilleries

FRP, RCC and wooden cooling towers for fermenter, condenser and spirit cooling in grain and molasses distilleries. Corrosion-resistant designs built in India since 1975.

Quick answer

What cooling tower is best for a distillery?

Most distilleries choose an induced draft FRP cooling tower. Fermenter cooling and distillation condensers create a large, steady heat load, and FRP resists the acidic, humid conditions around a distillery without rusting.

Fermentation needs cooling water close to a set temperature to keep yeast productive, so the tower should be designed for your hottest-season wet-bulb. Large grain and molasses distilleries often use multi-cell FRP, RCC or wooden towers.

Applications

Where cooling towers are used in distilleries

From fermentation to distillation and product cooling, almost every stage of a distillery rejects heat to the cooling water circuit.

Fermenter cooling

Removes the heat released during fermentation so yeast stays in its working temperature range.

Distillation column condensers

Condenses alcohol vapour from analyser, rectifier and other columns.

Spirit and product coolers

Cools spirit, ENA and product streams before storage.

Mash and molasses cooling

Cools mash and diluted molasses before fermentation.

Evaporators and dryers

Cools condensers on spent wash evaporators and DDGS dryers.

Utilities and power

Serves co-generation turbines, compressors, chillers and DG sets.

Challenges

We manufacture all three materials in-house, so we recommend the one that fits your duty, not the one we happen to make.

FAQ

Cooling towers for distilleries: FAQs

Which cooling tower is best for a distillery?

An induced draft FRP cooling tower suits most distilleries because it resists corrosion in acidic, humid conditions. Large distilleries may use multi-cell FRP, RCC or wooden towers.

Why does fermentation need a cooling tower?

Fermentation releases heat. If the mash gets too warm, yeast slows down or dies and alcohol yield drops. Cooling water from the tower removes this heat through fermenter coils or plate heat exchangers.

How do I size a cooling tower for a distillery?

Add up the heat loads from fermenters, condensers and product coolers, or give us the total circulating flow with hot and cold water temperatures. We also need your site design wet-bulb temperature and water analysis.

How do you control slime and biofouling?

Fouling is controlled mainly by water treatment. We help by selecting fill to suit your water quality and designing for easy access to the fill, nozzles and basin for cleaning.

Can you repair an existing distillery cooling tower?

Yes. We repair and reconstruct cooling towers of any make, and supply spares such as FRP fans, fills, nozzles, drift eliminators, fan stacks and gearboxes.

Do you supply distilleries outside India?

Yes. We have exported more than 1,500 cooling towers to the Middle East, Southeast Asia and Africa. Our factory at MIDC Murbad is close to JNPT port for fast shipping.
