TopChiller can design and manufacture all types of glycol chillers for you

Your Premier Glycol Chiller Manufacturer and Supplier in China

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.

TopChiller is a professional glycol chiller manufacturer and supplier since the year of 1999.

As the leading glycol chiller company, TopChiller 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.

Generally, a glycol water chiller consists of a refrigeration system, water system, and control system.

The refrigeration system is composed of an independent compressor refrigeration system, including compressor, condenser, thermal expansion valve, a plate heat exchanger(shell and tube heat exchanger), and refrigerant pipeline.

Let’s have a look at the working diagram of glycol chiller:

1. The compressor of glycol chiller

TopChiller glycol chiller uses top brand scroll and 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 TopChiller 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.

Of course, the temperature of air or water in the chiller must be lower than that of the refrigerant.

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.

With 20 years of design and make glycol chillers, TopChiller is willing to provide all types of high-quality glycol chillers for our valued customers.

Glycol chillers are widely used in modern industries, some typical applications of glycol chillers include cooling for breweries, wineries, cider mills, spirits, and some other critical industrial and commercial applications
