What is a Modular Chiller?
In modular chiller systems, you will have different types of chillers that posses’ double compressors with double circuit condensers and evaporators.
What are the Two Main Configurations of Modular Chillers?
Modular chillers have a plug-and-play concept that will assist in the configuration of systems with numerous units.
Such systems will allow you to use very high cooling capacities to chill different types of equipment.
Here are the two main configurations of modular chillers that you can choose from.
1. Modular Centralized Cooling Systems
The modular chillers have single units with parallel connections to build and increase refrigeration capacity.
2. Cascade Cooling Systems
Here, we have individual types of chillers that have been connected in series to cool thermal loads at high thermal drops.
It has the capability of achieving very high cooling capabilities that cannot be attained through single-stage refrigeration units.
What are the Main Components of a Modular Chiller?
Apart from the above classification, you can also classify the modular chillers as either water-cooled or air-cooled.
Despite the classification, here are the main components that you will find inside the modular chillers.
You can choose to have the air-cooled or water-cooled condensers which are responsible for eliminating the heat.
It employs cool flowing air or water to absorb the heat from the refrigerant which carries the excess from the evaporator.
The evaporator is responsible for eliminating the heat that comes from the system through pipes of flowing water.
It is the area where the refrigerant will pass and collect the heat and move the heat straight to the condenser.
· Storage Construction
This is the unit that will store the fluids that the machine needs for consistent temperature control.
In cases where there are limited operations, the storage construction will protect the fluid from freezing under cold temperatures.
Here, you will have double units of compressors that are responsible for compressing the refrigerants and increasing the pressure.
Apart from that, the compression will increase the volume of the refrigerant in readiness for the collection of heat.
· Control Unit
You will use the control unit to help configuring, programming, controlling and monitor the operations of the modular chillers.
In addition to that, it will help in controlling the operation temperatures even from a remote location.
· Expansion Valve
The expansion valve is responsible for changing the refrigerant from the gaseous state into the low-pressure fluid.
It reduces the volume of the refrigerant and allows it to flow back to the compressor for further processing.
· Alarm Systems
You will depend on the modular chillers’ alarm system to inform you of any problems within the modular chillers systems.
It will also inform when a particular process within the modular chiller system is complete.
Modular chiller compressor
What is the Working Principle of the Modular Chiller?
Modular chillers can either use air cooling or water-cooling systems to get rid of excess heat from the system.
Despite the system in play, the whole process begins with the preparation of the machine and setting it to play.
The refrigerant fluid such as glycol or a mixture of glycol and water will flow from the storage tank.
It will go through the compressor systems which will increase the volume and pressure of movement.
Here, the refrigerant will undergo compression which increases the volume and the pressure of movement.
At high speed, the refrigerant will flow straight to the evaporator section of the modular chiller system.
At the evaporator, the refrigerant will pick up the heat that the evaporator collects from the environment.
The evaporator has numerous pipes with cool water flowing through them collecting the heat from the environment.
As soon as it has enough heat it will transport heat to the evaporator which has refrigerants to collect heat.
Due to the heat, the refrigerant will change from the liquid state and to a gaseous state.
With enough pressure, it will flow carrying the heat with it straight to the condenser unit of the modular chillers.
While at the condenser, the refrigerant will get rid of the heat with the help of cool air or water.
This is the point where the type of coolant which can either be water or air will take full effect.
It will get rid of the excess heat from the system taking it to the cooling towers or the environment.
After that, the refrigerant will move from the condenser to the expansion valve.
At this point, the refrigerant will not have the heat within it and will change from a gas into a liquid.
The expansion valve will help in preparing the refrigerant in preparation for the next step as the process continues.

You will use both cooling towers and modular chillers to cool different equipment in different industrial applications.
One of the greatest differences between the modular chillers and the cooling towers is in the working principles.
Cooling towers use mechanical working principles where it has fans that help in blowing away the heat.
The fans will pull cool air from the environment and blow it to the hot equipment thus eliminating the heat.
On the other hand, modular chillers use components such as compressors, expansion valves, condensers, and evaporators to cool different equipment.
It can either employ water chillers or air chillers to help in getting rid of the heat from the system.
It has refrigerants that go through the entire system transporting heat from one station until it’s out of the system.
Is there a Difference between Modular Chiller and Portable Chillers?
Yes, there is a difference between modular chillers and portable chillers.
You can have portable chillers that are not modular chillers and modular chillers that are not portable.
