TRUSTED PROVIDER OF GLYCOL CHILLER IN VIETNAM
Glycol water chiller is one of the solutions for industrial refrigeration systems today. With the ability to cool water and glycol solutions. Glycol chiller meets the refrigeration requirements for industries such as: food and beverage, medicine, chemicals and many other industries.
The coolant commonly used in water chillers is a mixture of water and another substance with suitable thermal conductivity properties – such as a glycol compound. Glycol-based coolants include ethylene glycol or propylene glycol. The main advantage of glycol coolants is their anti-freeze properties. Pure water freezes at 0 degrees Celsius. While ethylene glycol 30% freezes at -14 degrees Celsius. The low freezing point of glycol mixtures is suitable for cooling items below the freezing point of water. Although glycol has a lower heat capacity than water (each kilogram of glycol is easier to heat than a kilogram of water). The larger temperature difference allows glycol mixtures to remove heat faster than pure water. Glycol mixtures are better suited for applications where the chiller must remove large amounts of heat quickly.

WATER TO GLYCOL RATIO FOR USE IN CHILLER COOLING PROCESS
Calculating the correct ratio of glycol to water in a refrigeration system. Depends on the coldest temperature you need during operation. If the refrigeration system is used indoors, where there is a lower chance of freezing. The amount of glycol required will be significantly less than glycol chiller used outdoors. It is very important to use the correct ratio of glycol to water in the refrigeration system. Adding too much glycol will result in the system operating inefficiently. However, not enough glycol can cause the system to freeze. This can cause pipes to burst and even destroy the refrigeration evaporator.
| GLYCOL RATIO | WATER RATIO | COLDEST TEMPERATURE |
| 16% | 84% | 0 °C |
| 24% | 76% | -5 °C |
| 32% | 68% | -10 °C |
| 40% | 60% | -15 °C |
| 45% | 55% | -20 °C |
| 50% | 50% | -25 °C |
| 55% | 45% | -30 °C |
ANALYZE THE ADVANTAGES OF GLYCOL WATER CHILLER
One of the advantages of GLYCOL chillers is the ability to cool water and glycol solution at the same time. Glycol solution is a liquid refrigerant with a high heat capacity. Allows to maintain a stable temperature and meet the strict requirements of industrial processes. When using GLYCOL chillers. Users can adjust the mixing ratio of water and glycol solution to create an optimal cooling environment for each specific application.
GLYCOL Chillers provide high performance and reliability in the refrigeration process. With advanced compressors and refrigeration systems. GLYCOL Chillers can quickly reach the desired temperature. Maintain stability during operation. This ensures that industrial processes such as production, storage and transportation are carried out efficiently and safely.
Besides, GLYCOL water chiller also designed to save energy. With advanced technology and intelligent control system. GLYCOL Chiller uses inverter technology to meet each current cooling requirement. This helps to minimize energy waste and save operating costs during use.
Frequently asked questions about glycol water chillers
Why use glycol instead of water?
Because glycol mixed into water lowers the solution's freezing point, letting the system run below 0 degrees C without the coolant freezing in the pipework and heat exchangers.
Where are glycol systems used?
In applications needing a coolant temperature below what plain water allows — breweries and beverage plants, food processing, ice rinks, and production processes requiring deep indirect cooling.
How does glycol concentration matter?
A higher concentration lowers the freezing point further but raises viscosity and reduces heat transfer, making the pumps consume more electricity. The concentration should therefore be just enough for the operating temperature, not stronger.
Does glycol need periodic checking?
Yes. The solution's concentration and pH need monitoring, because glycol degrades over time and can become corrosive, damaging the pipework and heat exchangers.
How does a glycol system differ from an ordinary chilled water system?
Beyond the coolant itself, a glycol system also differs in that the pumps and pipework are sized for a higher viscosity, the materials must be glycol-compatible, and a mixing tank and concentration monitoring procedure are required.
Does Tan Long build glycol systems?
Yes. Tan Long designs and installs glycol cooling systems for factories, complete from the chiller set through to the pumps, pipework and control system.
