Chiller Applications for Laser Technology

See how our chillers have been employed to assist with laser technology applications in the real world


Metal laser melting: this melting process generates components layer by layer, using 3D CAD data.


Cooling of the laser head of the fiber laser of one of the largest laser melting facilities (up to 160l construction volume) for the patternless production of large functional components or prototypes. The laser melting facility applies 2 fiber lasers, each with a 1,000 W output.




The technical task to be solved was to plan and produce a chiller, which could cover the cooling output of 2 lasers at a high control accuracy and allow for the global utilization with any application. The laser melting facility and the chiller should be provided to the end customer as a plug-and-play solution, with customer-specific water connections for the laser and optic circuits as well as the monitoring of the flow-rate measurement for the optic circuits as part of the design. Further requirements included an Anybus gateway communication interface for Modbus as well as the use of refrigeration components with UL approval.


The solution developed by KKT chillers is a water-cooled vBoxX 6, designed as a plug-in chiller, which can be inserted into the laser melting facility via telescopic rails. Thanks to a speed-controlled compressor, the cooling output adapts automatically to the load profile of the laser melting facility within a range of 2.5-5 kW, with a control accuracy of +/-1 K. The back of the vBoxX 6 is equipped with a connection panel for water and electrical connections. The solution features a dual-frequency design (50/60 Hz) suitable for utilization worldwide.

End Product:

Functional parts with sophisticated geometries and defined aero-dynamic or fluid-dynamic properties can be manufactured very quickly and cost-efficiently using the powerful laser melting machines from Concept Laser. They include fuel systems, guide blades and rotor blades, attachment systems and special heat protection components. Parts for engines and turbines, rocket elements, test vehicles and high-quality components for equipping the cabin and cockpit (interior) are other typical applications.

The generative metal laser melting process can be used to produce engine components, bodywork and structural parts as well as direct components for use inside vehicles precisely, economically and quickly.


After the technical testing of the entire system (laser melting machines and chiller) at the customer’s plant the start-up follows by trained service technicians at the end consumer’s plant.


Laser Perforating: Laser Cutting of airbags


Cooling of laser accessories of a CO2 laser.

Should You Use A Water- Or Air-Chilled Chiller?

Choosing the right chiller for your laser systems depends on several factors. For example, if you’re using a high-powered laser system, water-cooled chillers may be more suitable as they can usually handle greater heat loads with more efficiency.

On the other hand, air-cooled chillers are easier to install and provide a higher degree of flexibility. They are also less expensive to operate and maintain, so they may be better in environments with a lower power output and more limited cooling requirements.

If you need help deciding, our knowledgeable customer service team is here to help. All of our laser chillers are backed by an extensive warranty, so you can trust that your investment is secure.
