What is the Working Mechanism of Laser Chiller?

The Laser Chiller is a cooling unit installed in the laser industry to cool laser devices. Its working mechanism is given below.

Step 1

The refrigerant is installed for heat processing. The refrigerant that flows in the heat exchanger cools down by absorbing its heat collected from laser processing.

After that, it channels the coolant to circulate in laser tubes. The circulating coolant absorbs all of the extra heat produced during laser processing.

Step 2

While the refrigerant gets heated after heat absorption and changes its liquid phase into the gaseous phase, the gaseous refrigerant is sucked by the compressor for further processing.

Step 3

When the refrigerant enters the compressor from the suction valve, it is forwarded towards the rotating scrolls. These scrolls put compression force over refrigerant increasing its pressure.

Step 4

The refrigerant comes out from the compressor through discharge valves and enters the condenser. The gaseous refrigerant circulates under high temperature and pressure in condenser coils for heat discharging.

Step 5

The fresh air or chilled water supply is continuously provided over condenser coils for final heat dissipation. Chilled water/air absorbs all of the wasted heat from the refrigerant and rejects it away from the system.

Step 6

The refrigerant condenses from gaseous to liquid and passes from the expansion valve. After releasing its pressure at the expansion valve, the refrigerant enters the heat exchanger plate type

Step 7

When heats up in laser tubing again, the cooling fluids enter in convoluted tubing for heat exchanger. The refrigerant furthermore eliminates heat to regenerate the coolant for the laser device.

What are the Advantages of Using a Laser Chiller for your Laser Industry?

Different types of laser machines, such as fiber lasers, require a cooling effect for dispatching system heat. The Laser Chiller offers an assorted number of benefits as given below:

Superb Work Quality

As laser machine emits laser beam for cutting /welding a metal by evaporating the specified part. The Laser Chiller is discharging the heat produced during this process.

In this way, the laser machine and the product are retained from any damage under superb quality.


With the installation of a dual cooling circuit, the redundancy of the unit increased. For getting the particular temperature value, fluent cooling is provided by a dual-circuit system without interruption.

Working Efficiency

Recirculation system of refrigerant ensures continuous cooling production with temperature precision.

So the high working efficiency prevents the laser machine from heating effects.

Instrument Protection

As the tubes of CO2 laser are very sensitive and expensive. An increase in temperature may cause the slanting or breakdown of tubes.

So the laser machine is being protected from damage by heat discharging. The coolant absorbs heat from tubes and produces a cooling effect.

Environment-Friendly Behavior

The installation of an environmentally friendly refrigerant protects the environment from pollution.

Ozone-reducing chemicals are not being released from the refrigerant. That’s why the Laser Chiller has environment-friendly behavior.

What are the Prominent Applications of a Laser Chiller?

A Laser Chiller efficiently cools the laser machine that produces heat continuously during its operation. So it has a wide range of applications as given below:

  • Welding
  • Metal Cutting
  • Engraving
  • Photolithography
  • Printing
  • Drilling
  • Bio Optics
  • Injection Molding
  • Blow Molding

Laser Chiller Applications

Laser Chiller Applications

Which Type of Compressor is Used for Laser Chiller?

A Laser Chiller works at vapor compression principle. To increase the temperature as well as the pressure of the refrigerant, a compressor is installed.

These compressors can be of different types as given below:

Scroll Compressor

It is a commonly integrated compressor unit for its reliable and energy-efficient operation. Sound isolators are integrated for quiet or noise-free operation.

It allows the entrance of refrigerant by its suction valves.

The refrigerant is propelled ahead toward the rotating scrolls of compression. The compression force increases refrigerant pressure.

Reciprocating Compressor

Based on application requirements reciprocating compressor is also installed for Laser Chiller. It increases the pressure of refrigerant through its piston with the assistance of a crankshaft.

When the refrigerant enters the compression chamber, the piston rotates in a reciprocating manner and puts compression force.

What are the Uses of Laser Chiller?

A Laser Chiller is renowned for its diverse number of uses in different fields, as given below:

  • For metals cutting and welding in the manufacturing industry
  • For engraving on metals with different designs
  • For the food packaging industry
  • Chemical processing
  • Pharmaceutical Industry
  • For injection molding and blow molding of plastics
  • Medical surgery and medical imaging
  • Brewery and Beverage industry can also Laser Chiller
  • Food processing and packaging
  • For the printing process cooling

How Does Laser Chiller Cool Down CO2 Laser?

The CO2 laser is filled inside the discharge tube. Under electric supply, laser beams/radiations are produced, which are used for different purposes such as engraving, cutting, welding, medical surgery, etc.

Cooling of CO2 Laser

  • When the laser machine operates continuously, the heat is produced during radiation/beams evolving. When the heat goes above the average value, the CO2 can be damaged, either tube breaking or tilting.
  • To compensate for this problem Laser Chiller is installed that uses water as coolant and eliminates all of the system heat. For accurate temperature maintenance, a refrigerant recirculation system is installed.
  • Continuous recirculation of coolant around laser tubes prevents the temperature rise and keeps it at a set point. The coolant water absorbs the extra heat and transfers it to the heat exchanger’s refrigerant.
  • After regenerating its cooling effect, the coolant again flows around the tube for cooling production. Hence, in this way, the CO2 laser is being cooled.

What are Accessories Options for Laser Chiller?

Different Accessories options for Laser Chiller are given below:

  • Intelligent Temperature Controller
  • Flow Switches
  • Water by Pass
  • Solenoid Valves
  • Caster Wheels
  • Remote Control Kits
  • Water Filters
  • Check Valves
  • Multiple Pumps
  • Differential Pressure Switches

Which Evaporator is Installed in Laser Chiller for Collecting System Heat?

The evaporator/heat exchanger is integrated with Laser Chiller as a core component. It is involved in receiving the heat coming from laser processing.

The heat exchange occurs between the coolant and refrigerant at the evaporator. The plate-type evaporator is commonly used to occupy less space than the shell and tube type evaporator.

Plate Type Evaporator

It consists of two essential parts as convoluted tubules interspersed in the evaporator’s plates. Convoluted tubules increase the surface area for heat exchange.

The convoluted tubing causes a turbulent flow of the coolant for efficient heat discharge. At the same time, the refrigerant flows in plates circulating coolant and absorbs its heat.

When all of the heat is shifted from the coolant, the refrigerant gets evaporated and leaves the evaporator in gaseous form. The coolant is transferred towards the application with a flow rate as per application requisite.

How Does Fiber Laser Chiller Different From CO2 Laser Chiller?

There are different types of Laser Chiller based on application requirements such as CO2 laser and fiber laser etc. as:

Fiber Laser Chiller

This type of chiller provides high cooling and superb precision for fiber welding lasers.

The fiber laser is highly accurate because it generates a high energy beam through fiber. The beam is directed by delivery fiber at the workpiece to ensure high operation accuracy.

So by considering the requirements of this laser machine, the fiber laser is integrated with a dual cooling circuit for high precision.

A dual temperature control system and intelligent temperature controller are integrated. Multiple alarm systems also make it accurate and particular in cooling operation.

CO2 Laser Chiller

It is installed for a CO2 laser machine. It also requires exact temperature regulation for operation. But it is less accurate and puts high heat at the welding point as compared to fiber laser. It is a traditional laser machine.

CO2 Laser Chiller also consists of a dual refrigeration circuit. A coolant pump controls the flow of refrigerants.

A recirculation system is preferably installed for fluent cooling. It assures the cooling of tubes and prevents them from rupturing.

How Many Types of Laser Chiller is Available in the Market?

The Laser Chiller is of different types based on heat dissipation system and operation as given below:

Based on Type of Condenser

Water Cooled Chiller

A water-cooled condenser is integrated for heat discharge. The final heat dissipation depends on the cooling tower that provides chilled water.

Chilled water circulation release heat from the evaporated refrigerant and condense it in a liquid state.

Liquid refrigerant leaves the condenser to enter the evaporator. All other steps are the same as those of other chillers.

Air Cooled Chiller

If the refrigeration cycle consists of an air-cooled condenser, it would be called an air-cooled unit. The fresh air supply is constantly provided for the condenser.

The fan motor is also connected to the air supply. Air makes a round-over condenser coil, and the heat is transferred from refrigerant to ambient air. Ambient air discharges out for more fresh air.

Based on Operation

Vapor Compression Chiller

If the compressor is involved in the refrigeration cycle of the chiller for compression force, it would be called a vapor compression chiller.

The most commonly used chiller ensures continuous cooling production under refrigerant recirculation.

Vapor Absorption Chiller

In this type of Laser Chiller, the refrigeration cycle does not need a compressor for compression force.

But instead, an absorber and generator are installed for transferring refrigerant from generator to absorber.

This is widely used at an industrial level as well as a commercial level.

What are Anti-Freezing Strategies for a Laser Chiller?

During winter, at low ambient temperature, or a Laser Chiller outside installation, the chances of coolant freezing may occur. To compensate for this problem, there are three anti-freezing strategies as given below:

1 Operation for 24 Hours

Ensure to continue the operation throughout the day, assuring continuous water recirculation. The recirculation system will prevent coolant or refrigerant from freezing.

2 Removal of Water

When you have done the cooling operation, make sure to empty the Laser Chiller from the water. In this way, the coils will be prevented from freezing damages.

For seasonal shutdown, also remove the water from the unit or drags the unit indoors to prevent freezing. In this way, the unit may be prevented from direct water freezing.

3 Other Tips for Anti-Freezing

  • Mixing glycol with water coolant also increases the water freezing point. The glycol works with corrosion protection.
  • Secondly, make sure to use the anti-freezing agent in low concentrations because some anti-freezing chemicals can cause corrosion. Low concentration will meet the application needs better.
  • Make sure to short the usage time of refrigerant. The usage for long-duration starts the deterioration of the anti-freezing compound. Replace the refrigerant with a new one after a specific time duration.
  • Replacement of anti-freezing chemical after a twelve-month duration and use pure water circulation in summer.
  • Make sure to use the anti-freezing chemicals of the same brand so that no side reaction occurs as sedimentation or bubble formation.

Which Refrigerant is Used for Laser Chiller?

Refrigerant installation is necessary for a Laser Chiller to start the vapor compression cycle for cooling purposes.

The r410A, r404A refrigerant, r407C, and r134A refrigerant are installed. These refrigerants are environmentally friendly because they have zero reduction potential for ozone depletion.

The refrigerant flows in the refrigeration cycle for absorbing system heat.

After collecting all of the waste heat, it is processed by different refrigerant components and finally discarded heat to the environment.

How Does a Laser Chiller Helpful in Precise Laser Machine Operations?

The laser machine produces a laser beam that evaporates the pointed area for cutting, welding, engraving, etc.

But during laser beam production, heat is produced continuously that can damage the components of the laser machine and the material on which the laser is applied.

By Installation of Coolant Pump

So to prevent the laser machine from being damaged, Laser Chiller is used for proper operations. It is integrated with coolant pumps that control the flow rate of coolant.

The flow rate is adjusted as per application cooling requirements. In this way, the coolant pump prevents the laser from high or low cooling but sets it at standard value.

By Coolant Recirculation System

CO2 laser and fiber laser both require high precision with cooling capacity. This is possible by a recirculation system of refrigerant. The coolant in a specified amount enters in laser machine to produce a cooling effect.

After cooling, the coolant gets heated and transfer its heat to the refrigerant by entering into the heat exchanger.

After chilling, the coolant again moves to the system to maintain the précised temperature.

How Does the Mesh Filters of Laser Chiller Reduce Unit Downtime?

Reduction in Downtime of Unit

The mesh filters are fabricated with condenser coils of a Laser Chiller. The primary purpose of filter installation is to capture the dust particulates.

It also prevents debris accumulation or entry of any contamination inside the condenser coils.

In this way, the coils and whole condenser unit are protected from corrosion and interruption in operation. Clean water supply by mesh filter also reduces the maintenance costs.

There would not be any debris/dust accumulation, and there would be no need for deep cleaning. The service life also increases.

Thus the mesh filters decrease the downtime of the Laser Chiller by protecting it from dust, contamination, and corrosion.

What is Dual Cooling Circuit of Laser Chiller?

The Laser Chiller is mediated to discharge the heat produced during laser processing as welding etc. It is featured either with a single cooling circuit or dual cooling circuit.

Dual Cooling/Refrigeration Circuit

The dual cooling or refrigeration cooling circuit consists of dual condenser coils instead of connecting with individual compressors.

Both circuits consist of their compressor, condenser, and evaporator. One circuit assists in a constant flow of the refrigerant during operation.

While the other refrigeration circuit allows the refrigerant to flow in case of a high heating load, any fault or malfunctioning in one refrigeration cycle triggers the operation of another process independently.

This dual cooling circuit increases the redundancy of the Laser Chiller for reliable and durable operation.

Diagram of Dual Cooling Circuit of Laser Chiller

Diagram of Dual Cooling Circuit of Laser Chiller

How is Direct Cooling of Refrigerant Different from Laser Chiller Refrigerant Cooling?

Direct Cooling of Refrigerant

  • In this method, the refrigerant is cooled directly instead of getting cooled by the vapor compression cycle.
  • The refrigerant is directly cooled by its sudden expansion. According to Thomson’s effect, “sudden expansion of gas cause cooling.”
  • The refrigerant passes from the cold plate driving by the compressor. After compression, when the refrigerant is expanded, it becomes cool in cold plates. It does not require any recirculation system.
  • But some of its drawbacks is that vibration in the compressor or direct refrigerant cooling can deviate the laser beam from précised adjusted point.
  • Secondly, the refrigerant can be leaked to decouple it from the laser machine when cooling is not required.

Refrigerant Cooling by Laser Chiller

  • Refrigerant is being cooled for recovering chilling of coolant to discard system heat. The recirculation system is set up for the vapor compression cycle.
  • The refrigerant in evaporated form comes out from the evaporator and enters into the compressor. After the compressor, the condenser receives the refrigerant and cools it down by using chilled water or air circulation.
  • The benefit of using this refrigerant method is that the recirculation system assures continuous cooling for discarding system heal. The laser beam works at its specified point instead of deviation.

How to Maintain your Laser Chiller?

For efficient working and precision, the maintenance of a Laser Chiller is necessary. It can be done in the following way:

Cleaning of Condenser Coils

Ensure the cleaning condenser coils and wipe out all accumulated dust and debris from the evaporator tubing. Debris removal assures the smooth flow of refrigerant.

If you clean the tubing of the evaporator with chemicals and water, ensure their dryness by vacuum. Water retaining can cause rusting.

Inspection of Compressor Operation

Ensure that the compressor is running correctly. Inspect all of its components before starting operation.

There should be no oil leakage that can damage the compressor as well refrigerant viscosity. If there would be any leakage, amend it before a significant loss.

Integration of Hot Gas by Pass Valve

Also, integrate the hot gas bypass valve for tight temperature control. In this way, the cooling operation will be regulated and efficient.

Change of Coolant

Coolant containing anti-freezing should be changed with a new one after a specified time. With time anti-freezing agents start to deteriorate, causing rusting in the evaporator.

Water Replacement

Also, change the water to remove all of the accumulated impurities causing hindrance in operation.
