Industrial glycol chiller system Water cooled screw chiller

Glycol chiller is one kind of low-temperature chiller using glycol water as the circulating coolant to achieve minus temperature for industrial and process applications.

A chiller is a type of refrigeration system that cools a tub of glycol to reduce its temperature. The glycol is then pushed through a closed circuit of tubing or piping that is connected to the glycol chiller. This circulates cooled glycol and helps to reduce the temperature of whatever is attached to the system.

Oumal is a professional glycol chiller manufacturer and supplier for over 15 years.

As the leading glycol chiller company, Oumal provides various of glycol chillers from 1.5ton to 120ton refrigeration capacity, and air-cooled glycol chiller and water-cooled glycol chiller based on your specific requirements.

Why do we need to add glycol into the chiller?

As we know, water will be iced once the temperature getting 0℃ or even below, glycol is helping water anti-freezing into iced, that’s why we call it is glycol chiller.

Using a glycol-water mix as a chiller coolant has various benefits over the use of plain water as a chiller fluid. These advantages are due to its unique physical properties which include a lower freezing point than water.

Generally, A glycol chiller plant is composed of a refrigeration component and tubing containing a glycol-water mixture as coolant. Chilled fluid from the refrigeration unit is channeled through the piping associated with a thermal exchanger surrounding a heated process. After absorbing heat from the associated process, the warmed coolant is returned to the refrigeration unit for cooling after which the process is repeated.

For many chiller types, ethylene glycol is mixed with water at a ratio of 60/40. This higher percentage of glycol boosts the mixture’s antifreeze properties significantly. This is useful in cases where rapid cooling is required. In these situations, a process can be cooled to very low temperatures without freezing the coolant within its piping.

A conventional water chiller works on the principles of heat transmission between various mediums both fluid and solid. These cooling systems work either by heat absorption or vapor compression. The basic components of a water chiller system include a refrigeration unit and a piping system that circulated chilled coolant.

The working diagram of glycol chiller:

1. The compressor of glycol chiller

Oumal glycol chiller uses top brand scroll or screw-type compressor features energy efficiency, low noise, and long service time.

In order to ensure that the pressure inside the evaporator is low enough and that the refrigerant is at such a low temperature, the compressor is used to pump out the evaporated refrigerant and compress the low temperature and pressure into the high temperature and pressure refrigerant gas.

2. Condenser for a glycol chiller

 Glycol chiller designed by Oumal using air-cooled type or water-cooled type condenser for your choice.

The refrigerant with high temperature and pressure is condensed into liquid in the condenser. The refrigerant in the condenser releases heat in the middle of air or water with a lower temperature than it.

3. Thermal expansion valve in a glycol chiller

The thermal expansion valve plays an important role in a glycol chiller. The refrigerant of glycol chiller drops from the condensation pressure to the evaporation pressure, so the liquid from the condenser can be placed in the liquid receiver.

At this time, the refrigerant is in the state of normal temperature and high pressure, and then passes through the expansion valve to reduce the boiling point, and the liquid enters the evaporator to absorb heat and evaporate.

4. The evaporator in a glycol chiller

There is two type of evaporator in glycol chiller- shell & tube type and plate heat exchanger.

After passing through the thermal expansion valve, the low-temperature and low-pressure refrigerant liquid exchanges with the evaporator.

Once the heat is absorbed, it becomes saturated or overheated steam, which can be returned to the compressor for refrigeration.
