Independent production of sheet metal and heat exchanger . 9L cooling tank, fast cooling.
Adopt IPG fiber laser for welding and cutting sheet metal, adopt minimize risks of water and refrigerant leakage and improve quality 

Digital temperature display
The digital temperature display is able to indicate water temperature and alarm codes.

Ease of moving and water filling.
The firm handle can help move the water chillers easily.
Inlet and outlet connector equipped. Multiple alarm protection.
The laser will stop working once it receives alarm signal from the water chiller for protection purpose.
High speed fan
The high speed fan is installed to ensure high cooling performance.
Easy water draining
It is suggested to replace the cooling water(distilled water or purified water as cooling water) every 3 to 6 months.

Connection diagram between water chiller and laser machine

Water outlet of the water tank connects to water inlet of the laser machine while water inlet of the water tank connects to water outlet of the laser machine. Aviation connector of the water tank connects to the aviation connector of the laser machine.


In order to guarantee the equipment will not be damaged while cooling water circulation is out of control, CW-3000series water cooler possess a low flow alarm protection.

Causes of the cooling water circulation alarm and the working condition table

Note: The flow alarm is connected to the normally open relay and normally closed relay contacts, requiring operating current less than 5A, working voltage less than 300V.


Method of exchanging water in the water tank and the exchanging frequency

Method of exchanging water in the water tank

Drain the waste water out of the water tank through the drain outlet and fill the clean water into the tank through the filling hole

Exchanging Frequency

The purified water should be exchanged once a month and the running water should be exchange twice a month. The quality of the circulating water will directly influence the service life the laser tube.It is recommended to use purified water.


It is very simple to install this industrial cooling machine. The first time installation of the new machine can be carried out by following steps.

Open the package to check if the machine is intact and all the necessary accessories are completed.


Open the injection port to feed cooling water. (Do not let the water spill over!)


According to system conditions, please connect the water inlet and outlet pipe well.


Plug in power, turn on the power switch. (Do not start up without water in the water tank!)

(1) Power switch turned on, the circulation pump of the chiller starts working. The first time of operating may cause more bubbles in the pipe leading to a flow alarming occasionally, but running for a few minutes later, it will go back to normal.
(2) After the first boot, you must immediately check whether the water pipe leaks.

Check the water level of the water tank again. (It should be 80-150cm from the surface of water to the injection port)



Please ensure that the power supply and electrical outlet are in good contact and the earth wire must be firmly grounded!


Please make sure there is stable and normal voltage for the working chiller!

As the refrigeration compressor is more sensitive to the power supply and voltage, so the operating voltage of our standard product is of 210 ~ 240V (110V model is of 100 ~120V). If you do need a wider operating voltage range, customization is available for us.

Unmatched power frequency can cause the chiller damage!

Please choose model of 50Hz or 60Hz according to actual circumstance.

To protect the pump, it’s strictly forbidden to run the chiller without water in the storage water tank!

The new machine is packed after draining whole water in the tank, so please make sure the tank has water inside before machine starting, otherwise it’s easily to have the pump damaged.
To drain through circulating pump is strictly prohibited!

Please be sure that the air inlet and air outlet are in good ventilation!

There must be at least 30cm from obstructions to the air outlet which is in the back of the cooler, and should leave at least 8cm between obstructions and the side air inlet.

The cooling water must be drained if the cooler is out of use for long time or before being transported.

To protect laser heating devices , the radiator fan of cooler will suspend to work when water temperature is lower ( about 10℃ ) , and it will restart to run when water temperature rises to higher ( about 20 ℃).
