What is a Low-Temperature Glycol Chiller?

A Low-Temperature Glycol Chiller is specially manufactured and designed for industrial processes.

You can identify by its name that it is used for low-temperature cooling requirements.

A Low-Temperature Glycol Chiller provides non-stop cooling. It can drop the temperature of the fluids to -40 degrees Fahrenheit.

A Low-Temperature Glycol Chiller uses a glycol mixture to meet the low-temperature requirements of your application.

It uses propylene glycol and ethylene glycol as a cooling medium in different industries.

Propylene glycol is mostly used in the food and beverage industries as it is harmless for human health.

A Low-Temperature Glycol Chiller dissipates the heat from the system into the air with the help of a condenser.

The complete guideline about working a Low-Temperature Glycol Chiller is described in the next sections.

A Low-Temperature Glycol Chiller uses glycol and water mixed in a specific ratio to fulfill the low-temperature requirements below the freezing point to cool down various applications.

It first cools the glycol mixture then circulates it through the pipes to cool down machinery and products etc.

What are the Working Principles of a Low-Temperature Glycol Chiller?

A Low-Temperature Glycol Chiller uses glycol as a coolant. Glycol is a thick translucent chemical compound.

Glycol is a very environment-friendly coolant as compared to other fluorinated gases. Other fluorinated gases can greatly affect the environment.

A Low-Temperature Glycol Chiller uses different processes and working principles to fulfill the requirements of large-scale industrial applications.

The refrigeration cycle for the Low-Temperature Glycol Chiller begins with low-pressure gas or liquid driven to the evaporator.

The evaporator boils the refrigerant by using heat obtains from the process water and glycol mixture.

It changes the state of a low-pressure liquid to a low-pressure gas.

This low-pressure gas then enters the condenser where ambient air dissipates heat from it.

When the heat is removed from high-pressure gas it becomes a high-pressure liquid then high-pressure liquid travels to the expansion valve.

The expansion valve also controls the amount of liquid refrigerant that enters the evaporator to restart the refrigeration cycle.

The condenser of a Low-Temperature Glycol Chiller can be of two types an air-cooled or water-cooled.

An air-cooled condenser of a Low-Temperature Glycol Chiller uses air to condense the high-temperature refrigerant gas into a liquid.
