Features and Advantages:

The excellent characteristics and advantages of Modular Chiller available are:

  • It is compliant with ASHRAE mechanical ventilation standards and has a smaller refrigerant charge. So you do not have to install additional ventilation refrigerant monitoring, helping you with a significant reduction in the total cost.


  • You can adapt it for the heat pump to offer both heating and cooling capacities. Using this flexibility, you can heat or cool your facility depending upon your process requirements.


  • Being small in size, it is suitable for retrofitting old air conditioning and heating equipment. It also allows easy module fitting within an available HVAC system. More modules provide better redundancy to your system.


  • In case of single module malfunctioning, you’ll have to go through reduced downtime as each module can individually provide cooling to your system because of its separate power.


  • A primary module controls the other modules as it features a microprocessor controller. A communication cable links this microprocessor to the controllers present in other modules.

Modular Chiller: The Ultimate FAQ Guide

This guide will help you choose a high-performance modular chiller for your applications.

So, if you want to learn about the quality specifications, working principles, or configurations, every piece of information is right in this guide.

Keep reading to learn more.

What is a Modular Chiller?

Modular chillers are cooling systems that have multiple chillers coupling together to make expandable chilling systems.

In modular chiller systems, you will have different types of chillers that posses’ double compressors with double circuit condensers and evaporators.

Modular chiller

Modular chiller

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.

· Condensers

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.

· 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.

· Compressors

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.

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.

Cooling tower

 Cooling tower

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.

Implying that, there are stationary modular chillers and mobile modular chillers for different applications.

Air-cooled chillers and water-cooled chillers are types of chillers that you can employ in different cooling applications.

Both water-cooled and air-cooled chillers have similar components including condensers, evaporators, expansion valves, and compressors.

Apart from those similarities, you will house the water-cooled chillers in mechanical rooms to protect them from damage.

It also uses water as the main cooling agent the help in getting rid of excess heat from the system applications.

On the other hand, you will install the air-cooled chillers outside where it can have proper access to plenty of air.

Apart from that, you will depend on air as the main cooling agent for cooling off the excess heat.


Water cooled chiller

Why use Variable Speed Compressors in Modular Chillers?

You will use the variable speed compressors for controlling the speed at which the compressors work.

With the variable-speed compressor, you can simply increase and reduce the speed at which the compressor works.

You must have a look at the heating or cooling load within the system as you control the heat elimination process.

It will provide the compressor with a particular voltage thus helping in saving energy from wastage.
