Lando is a leading Glycol Chiller manufacturers and suppliers in China. These glycol chillers use the BITZER compressor for expanded low-temperature applications with the 2nd generation of the 2-stage compressor. It can provide low-temperature water from -30℃ to 25℃. Since glycol is a food-grade anti-freeze, these types of chillers are most frequently used in the food and beverage industry. Glycol chillers are commonly used for cooling fermentation tanks, bright tanks, and wort coolers in the brewing industry. Our experienced engineering team is qualified to provide a tailor-made low-temperature cooling solution for your unique need.
What is a glycol chiller？
Glycol chillers are refrigeration systems that circulate an anti-freeze and water solution to help cool a variety of equipment and processes. These chillers use an anti-freeze called glycol from which they receive their name. Glycol comes in two varieties: ethylene glycol and propylene glycol.
The first is ethylene glycol which is a colorless, odorless, low volatility liquid that does not contain any additives. Ethylene glycol is perfect for recirculation chillers and has good rust inhibitors. Glycol chillers are used to provide reliable temperature control for fermentation and storage temperatures. It can be used safely in industrial settings due to its relatively high flashpoint at 240°F. The second is propylene glycol which is the most often used in food.
How does the glycol chiller work?
At the heart of a glycol system is the glycol chiller itself. A glycol chiller is actually a refrigeration system consists of two key parts: a refrigeration unit which uses electrical energy to produce a cold fluid, and heat transfer coils which move cold fluid from the refrigeration unit to the target area and hot fluid from the target area to the refrigeration unit. The refrigeration unit often consists of a compressor with some compressible heat transfer fluid such as freon. This cooled liquid is pumped through a looped circuit of tubing connected to the input and output sections of the glycol chiller. Once connected, glycol will now circulate through the heat exchanger and the vessel will be cooled.
Why use Glycol?
Glycol is antifreeze and it can be cooled below freezing temperature without icing up the insides of the chiller. Glycol also acts as lubrication for the pump. It also holds temperature better than water in the long tubing runs. This can be very helpful in cold weather when you want the fermentation process to complete quickly.
The low freezing points of glycol mixtures make them ideal for cooling items below the freezing point of water.
Pure water freezes at 0 degrees Celsius (32 F)
pure ethylene glycol freezes at -12.9 C (8.9 F).
10% ethylene glycol freezes at -3.4 C (25.9 F)
30% ethylene glycol freezes at -13.7 C (7.3 F)
60% ethylene glycol freezes at -52.8 C (-63 F).
From the above analysis, utilizing a glycol-based chiller will take advantage of its antifreeze properties to make sure that the correct mix of antifreeze fluid protection is put in the chiller for effective performance.
