Types of Industrial Chillers: Exploring Chiller Units for Various Applications
Industrial chiller units are used across a wide range of applications to maintain precise temperature control
and manage heat removal. Here, we'll explore different applications and the types of chiller units commonly used
Beverage and Food Refrigerators
Safe and delicious food and drinks can only be guaranteed if their storage temperatures are kept constant.
Chilling liquids like milk and juice or preserving food goods requires food and beverage chillers. Both
air-cooled and water-cooled chillers are available, with the choice of type and size determined by the volume of
product to be chilled and the desired temperature range.
Medicinal Cold Packs
Medical chillers for healthcare applications play a crucial role when it comes to keeping sensitive medical
equipment, like MRI and CT scanners, at just the right temperature. With precise temperature control, these
chillers maintain consistent performance and prevent overheating, which can compromise equipment and patient
safety. By accurately managing humidity levels, chillers also aid in keeping spaces hygienic.
Commercial and industrial buildings like hospitals, data centers, and factories rely on air conditioning
and heating chillers. These chillers are used to cool fluids like water for use in HVAC systems and
industrial processes. These chillers come in a wide variety of sizes, from compact models that can be hidden
beneath a desk to massive installations that take up a whole room. The efficiency, cost, and lifespan of a
company's HVAC mechanical systems can all be improved by selecting the right size and kind of chiller.
Metal-Working Cooling Units
High-quality metal plating and chemical procedures are only possible with the help of industrial chillers for
metal finishing. Inaccurate temperature regulation can lead to corrosion, pitting, and other flaws; hence, these
chillers are indispensable. Therefore, it is vital to consider the application's scale, the temperature range
needed, and the chemicals used when choosing an industrial chiller for metal finishing.
Mechanical Cooling Systems
Large-scale gear and equipment can benefit from the cooling effects of an industrial chiller in various
commercial and industrial settings. There are a variety of industrial chillers to choose from, such as those
that use air, water, or evaporative cooling. Industrial chillers can provide dependable cooling for years if
properly planned and maintained.
Equipment for Cooling Plastics
Chilling systems are essential in the plastics industry since accurate temperature control is critical for
production. Investing in a high-quality chiller system is a great way to cut expenses without sacrificing
productivity or quality. Chillers can be air- or water-cooled, depending on the specific application's needs.
What are the different types of chillers?
Here, different kinds of chillers are commonly used in various industries and applications.
Types of Industrial Chillers by Classification
What is a chiller surge? Many sectors rely on industrial chillers to keep processes and equipment at ideal
temperatures. Depending on how you categorize them, you'll find various. Most industrial chillers fall into one
of these categories:
Both vapor compression chillers and vapor absorption chillers are common types of chillers. In contrast, vapor
absorption chillers use heat to transfer the refrigerant around the system.
Both vapor compression chillers and vapor absorption chillers are common types of chillers. While vapor
absorption chillers use heat to transfer the refrigerant around the system.
1- Vapor Compressor Chillers
Vapor compression chillers use an electrically driven mechanical compressor to do the same thing.
The most popular type of chiller is the vapor compression variety, which has two subtypes: air chillers and
2- Vapor Absorption Chillers
Vapor absorption chillers are an alternative to vapor compressor systems, in which the refrigerant is compressed
and then compressed again as it circulates the system. The system consists of an absorber, pump, and generator
rather than a compressor, as in traditional vapor-compressor chillers.

Types of Industrial Chillers by Condenser Type
Industrial chillers are essential for cooling processes in various industries, and they come in different
types to suit specific applications. Here are some common types of industrial chillers:
1- Water-Cooled Chillers
The primary return of a water-cooled chiller is used to draw water into the evaporator. The water is
cooled in the evaporator and sent to the water tank through the system's primary supply. The air-conditioned
areas receive chilled water via a water pump.
The air handler is cooled by cold water that circulates through each room. Because of the second rule of
thermodynamics, heat can move from hotter to colder areas without any conscious effort on the part of the
If this is an air conditioning application, the air handler's air will cool after the heat is transferred to the
chilled water. The climate-controlled portions of the equipment are cooled by a fan that blows air through
ducting and into each location. The cycle continues when the warm water is again cooled in the system's chiller.
Each successive cycle of heat absorption from the water requires the refrigerant to give up some of the heat it
gained in the previous cycle. The evaporator transfers the low-pressure, heated refrigerant to a compressor
powered by an electric motor. The refrigerant is heated and pressurized by the compressor before being sent to
2- Air-Cooled Chillers
In terms of functionality, an air-cooled chiller is equivalent to a water-cooled chiller. You'll find the
critical distinction between an air-cooled and a water-cooled chiller in the condenser. An air-cooled chiller
blows air over a condenser coil to remove heat from the refrigerant, while a water-cooled chiller uses water to
cool the liquid. Each chiller works in the same fundamental way to remove heat from the system.
The compressor raises the refrigerant's temperature and pressure before reaching the condenser, where a fan
draws ambient air. The condenser removes heat from the refrigerant before releasing it into the atmosphere. The
refrigerant flows back via the expansion valve into the evaporator when the cycle is complete.
3- Scroll Chillers
A refrigerant is compressed by a scroll compressor in a scroll chiller. A fixed scroll plate and a
rotating orbiting scroll plate work together to increase the temperature and pressure of the refrigerant (Link:

has been liquefied.
4- Screw Chillers
It's worth noting that screw compressors can manage greater capacities than scroll compressors when
comparing the two. Screw chillers range from 30 to 400 tons or more, whereas the tonnage range for scroll
chillers is 2 to 140 tons (60HP maximum single compressor size).
Screw chillers, in contrast to scroll chillers, employ one or two rotating screws to compress the refrigerant,
applying force. Screw compressors are ubiquitous in the petrochemical and industrial processing sectors.
5- Explosion-Proof Chillers
Industrial explosion-proof chillers
are necessary for some pieces of potentially explosive machinery.
Manufacturers of explosion-proof chillers use a strengthened, specific design to prevent their internal workings
from being damaged by combustible substances. Thanks to this design, employees, machinery, and buildings are all
safe from any potential explosions.
Explosion-proof air-cooled chillers are difficult because so few companies specialize in making them. A reliable
manufacturer who adheres to National Fire Protection Association regulations and codes should be sought out if
you need an explosion-proof chiller in potentially dangerous environments.
6- Glycol Chillers
The digital temperature controller in an industrial glycol chiller is highly accurate. With the help of
this controller, you can keep perishables at safe temperatures at all times. Glycol chillers are commonly used
in the wine and beer industries for this very reason.
7- Low-Temperature Chillers
Some industrial operating conditions require the leaving fluid temperature to remain below 35 degrees
Fahrenheit. Low-temperature chillers ensure equipment operates efficiently for applications such as
petrochemical processes and ice rink cooling that require low leaving liquid temperatures. Some units can run to
as low as -40 degrees F going fluid temperature. At these conditions, special heat transfer fluid is required.
8- Centrifugal Chillers
Centrifugal chillers are well-liked due to their high chilling capacity and low energy consumption. Large
commercial and industrial HVAC systems frequently include centrifugal compressors, which use centrifugal force
to compress the refrigerant.
Chiller surge can occur in different types of chillers, but it is more commonly associated with centrifugal
