The process of distillation by fermenting releases heat, if the brew becomes too hot, flavors can be affected, alcohol levels may change, and yeast can die completely. So a distillery chiller is mandatory to control temperature.Distillery is also referred to as fluid or glycol chiller and is commonly used in Brewery, Winery production operations and fermentation processes.
Distillery chiller designed by Tongwei will pump water out of the tank and through a heat exchanger, and then out to your distillery process. The heat exchanger inside the cold-water skid chills the water with glycol from the chiller unit. The buffer tank starts out the day full of pre chilled water. As the production day proceeds hot water is returned to the tank. Since the selected chiller has a smaller cooling capacity than the amount of heat being put into the water by the distillery, the temperature of the water in the tank rises throughout the day. We can size the tank and chiller in such a way that the temperature of the water doesn’t get too high, thus preventing an adequate amount of cooling being done later in the day. After the production day has concluded the chiller will continue chipping away at the heat stored in the water tank until it gets back down to the initial set temperature for the water in the tank, leaving it ready for the next day’s production.

There are two types of glycol distillery chiller: one is air-cooled glycol distillery chiller ,the other is water-cooled glycol distillery chiller ;
Air-cooled glycol distillery chillers use ambient air to dissipate heat from the brewery processes. They are energy-efficient, space-saving, and less maintenance that helps save money.
Water-cooled glycol distillery chillers use water from an external water cooling tower to dissipate heat from the brewery processes. These systems are longer lifespan, Relatively quiet, and more consistent cooling performance than the air-cooled brewery chiller.

Glycol Chillers help with temperature control for spirits and RTDs — “ready to drink” or premixed drinks — during fermentation and distillation. This precise control prevents overheating, which can kill yeast and spoil batches, providing consistent, high-quality products. With better temperature control, chillers may enhance the flavor and clarity of spirits, delivering a superior final product.
Chillers’ consistent cooling may allow quicker processing times as equipment doesn’t need to cool down naturally. Faster cooling means more production cycles in less time, boosting overall output. With chillers, you can maximize production capabilities, making your distillery more productive and profitable. It would be akin to having an always-ready, efficient assistant on the job.
Because distillery chillers help prevent overheating, they may extend the life span of distillery equipment. Consistent cooling reduces thermal stress on machinery, which may lead to fewer breakdowns and maintenance issues. This result prolongs the life of fermenters, condensers, and other vital equipment, ensuring they remain in top working condition for longer.
Modern distillery chillers are designed to be energy-efficient, reducing overall power consumption. They use advanced technology to provide precise cooling with minimal energy use, resulting in lower utility bills. Efficient cooling systems can also help reduce the need for additional cooling equipment.
Glycol Chillers ensure a stable production environment through optimal temperatures throughout the distillation process. This consistency reduces the risk of production halts. Consistent cooling also helps to maintain uniformity in each batch. This means that distilleries may lead to predictable, reliable output.
The most commonly used coolant in a chiller is water or a mixture of water-glycol. Glycol-based coolants consist of either ethylene glycol or propylene glycol. The main advantage of glycol coolants is their anti-freeze properties. Pure water freezes at 0 degrees C, while 30% ethylene glycol freezes at -14 degrees C. The low freezing point of glycol mixtures makes them ideal for cooling items that are below the freezing point of water. Although glycol has a lower heat capacity than water (each kilogram of glycol is easier to heat than one kilogram of water), the high temperature difference allows the glycol mixture to dissipate heat more quickly than pure water. The glycol mixtures are more suitable for applications where the chiller must quickly dissipate a large number of heat. In addition to providing excellent heat transfer parameters, glycol tends to discourage algae growth in heat transfer equipment.

It is important to use the proper ratio of glycol to water mixture in the cooling system depends on the coldest temperature you need during operation, as insufficient glycol can cause the system to freeze, possibly bursting pipes and even destroying the chiller evaporator even may damage the glycol chiller, while too much glycol to a chiller system will result in an inefficient system.But what’s the best ratio for glycol and water mixtures?

There are SIX important chiller specifications you need consider when you choose a chiller for your application :the cooling capacity for chiller ,the voltage required for operation, the associated pump horsepower and flow rate (contact us for custom selection), refrigerant, and the evaporator type.
There are two types of glycol distillery chiller: one is air-cooled type, the other one is water-cooled type.
Air Cooled glycol distillery chillers use aluminum fin+fan as condensers that is similar to the “radiators” in a car.They use a fan to force air through the refrigerant coil. Unless they are specifically designed for high ambient conditions, air-cooled condensers need to operate effectively at an ambient temperature of 45℃ or less.
Water Cooled glycol distillery chiller use shell and tube as condensers.The heat enters the condenser water from the refrigerant vapor. The warm condenser water is then pumped to the water cooling tower, where the heat from the process is eventually vented to the atmosphere.
One of the most frequently ask about how we can know the cooling capacity for chillers. We use KW ,Ton, But/h,Kcal/h to choose chiller cooling capacity :1 KW=860 kcal/h ; 1 TON=3.517 KW;
1 KW=3412 Btu/h;
Then we also need know :brew house capacity, quantity and BBL for the fermentation tanks, quantity and BBL for the brite tanks as well as the wort cooling.
Different countries and regions have different standards for industrial electricity, the common power supplies are 208-230V, 380-420V,440-480V,50Hz or 60Hz, 3phase.
Such in Philippines ,the power supply is 220V 60HZ 3PH , 380V 60HZ 3PH ,460V 60HZ 3PH;
in Singapore and Malaysia ,the power supply is 415V 50HZ 3PH;
in Mexico ,the power supply is 220V 60HZ 3PH;
In USA ,the power supply is 208V 60HZ 3PH;575V 60HZ 3PH;480V 60HZ 3PH and so on
As a professional low temperature glycol distillery chiller supplier &exporter,we have our own shipment forwarder to arrange the shipment .Our chiller machine is with plywood packing,which prevent damage during transportation and meet export standards.There are three ways can delivery your chiller unit :
1. Ship by Air: As the chiller is with compressor ,water pump and fans ,the compressed refrigerant and oil inside the compressor is a dangerous item with the possibility of explosion , so it needs to release the compressed refrigerant before transportation. (It means that water chiller without refrigerant when choosing this shipping way. After the machine arrives at your destination, you need to add refrigerant by local professionals. The airline company also request us to provide many documents to prove that the chiller not a dangerous product. The freight cost by air is very high may be higher than the cost of chiller , So By air for delivery is not the mode of transport recommended to our customer.
2. Ship by Sea: The transportation time is longer than by air , but the freight cost is cheap ,and there is no need to add refrigerant after the equipment arrives at the destination.This shipping way is the most suitable mode of transportation for you to delivery your local port.
3.If you have your own shipment container in your other supplier in China, we can help you delivery the chiller machine to your supplier in any city of China .
