CW-5200DG Industrial Water Chiller for CNC/ Laser Engraver Cooling Machine

Industrial Water Chiller for CNC/ Laser Engraver Cooling Machine CW-5200DG Hot water cooling chiller

CW-5200 Series are professional cooling machines referring to international, advanced thermolysis cooling system designed, suitable for small water-cooled cooling devices requested machinery. The  Industrial Water Chiller has a patent Certificate, CE and RoHS Certificate. It has been sold largely to Europe, South America, Asia and other markets.

It is designed for cooling the one CO2 glass laser tube under 130W/150W of the laser engraving and cutting machine.

Under normal circumstance, the new intelligent temperature controller does not need to adjust the controlling parameters.

It will self-adjust controlling parameters according to room temperature to meet cooling demands.

Application

Mainly used to have the heat generated during the laser device working that gone through the refrigerating cycle in compressor refrigeration system and eventually transferred to the air. The water temperature is able to be adjusted. There are 2 specifications as 1 water outlet / inlet and dual water outlet / inlet, applicable to cool single laser glass tube.

Economic cooling equipment, easy to install and operate, compact and easily movable.

Our industrial water chillers are popular for its 2 temperature control modes as constant temperature and intelligent temperature control. Under intelligent mode, the water temperature is adjusted according to ambient temperature. With this 1 key solution, customers no longer need to worry about water temperature adjustment of seasonal changes.

How to  use

Installation steps

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

B. Open the injection port to feed cooling water.

Observe water level gauge while adding water slowly, be careful not to have water overflowed! For the cooling of carbon steel equipment, water should be added with an appropriate amount of anti-corrosion agentia. Working in cold north area, it’s better to use noncorrosive antifreeze fluid.

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

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

(1) Circulation pump of the chiller starts working. Operating for the first time may produce bubbles in the pipe, which occasionally leads to flow alarming. In such case, it will go back to normal after running for a few minutes.

(2) After the first boot, please immediately check whether the water pipe leaks.

(3) Power switched on, if the water temperature is below the set figure, it is normal that fans and other components of the machine do not work. The temperature controller will automatically control the working conditions of the compressor, magnetic valve, fans and other parts based on the set controlling parameters.

(4) As it takes a longer time to start the compressor and other components, the time you take might range from seconds to minutes, please do not turn the power off and on again frequently.

E. Check the water level in the water tank.

The first startup of the new chiller empties the air in the water pipe, leading slightly water level decline. In order to keep the water level in the green area, it’s allowed to replenish adequate water. Please observe and record the current water level and inspect it again after the chiller has been running for a period of time, if the water level drops obviously, please re-inspect the water pipeline leakage.

F. Adjust parameters of temperature controller.

CW-5200 series use an intelligent thermostat. Normally users do not need to adjust it. If it's really necessary, please refer to "Operating status and parameters adjustment."

Notice

Alarm Function

E1- Over high room temperature

E2- Over high water temperature

E3- Over low water temperature

E4- Room temperature sensor failure

E5- Water temperature sensor failure

Remark:

When alarm occurs, the error code and the temperature will be alternately displayed.

In alarming state, the alarm sound could be suspended by pressing any button, but the alarm display

remains until the alarm condition is eliminated.

Flow alarm and output ports:

In order to guarantee that the equipment will not be damaged when cooling water circulation is out of control, CW-5200series chillers possesses an unique low flow alarm protection.

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.
