FIBER laser chillers and cooling units

In fibre laser systems, thermal stability directly affects cutting quality and reliability. The chiller dissipates heat from the FIBER source and the cutting head, keeping the coolant within the required range and maintaining constant flow. As a result, the beam power remains stable, the piercing process is consistent, and the risk of alarms or unplanned downtime is reduced. In practice, a properly selected chiller supports edge cleanliness, minimises build-up and helps maintain the cut geometry along the entire length of the part.

The choice of unit should be based on the laser power and working conditions — the longer the cycles and higher the speeds, the greater the required cooling capacity. Important parameters include temperature stability, actual flow rate and protective functions such as liquid level control, and flow and temperature sensors with alarm signalling. For facilities operating in cooler environments, protection against condensation on optical components and the possibility of using glycol-based mixtures according to the manufacturer’s recommendations are also relevant. Correct installation and operation are equally important: clean coolant, unobstructed circulation, proper ventilation around the heat exchanger, and regular inspection of filters and seals. These simple actions significantly extend the service life of the source, head, and the entire optical-mechanical system.

If you need assistance with selection, please provide the laser power, typical material thickness and operating mode — we will suggest models with the right cooling capacity to maintain consistent process parameters and repeatable cutting quality under your working conditions.
