Introduction:

It is designed for cooling the one CO2 glass laser tube under 150W of the laser engraving and cutting machine. (Its emitting rate is higher than 60 %.) 
Cooling capacity is 800W.
Have design patent Certificate, CE and RoHS Certificate.
This Water Chiller has been sold largely to Europe, South America, Asia and other markets.
Economic cooling equipment, easy to install and operate, compact and easily movable.

Feature:

• It is suitable for cooling the laser tube under 150W, and the temperature can be adjusted precisely.
• You can choose different models according to local voltage and frequency.
• It can extend the using life of laser tube and ensure the engraving effect better.
• Small thermolysis water cooler, energy saving, long working life and simple operation
• with completed water flow and over high temperature alarm functions
• It can control the water temperature; precision is ±0.3℃, which provide stable working conditions for laser devices.
• This series of water chillers adopt intelligent controller, which need not adjust the control parameters under normal 
circumstances, it will automatically adjust control parameters according to room temperature changes, to meet the cooling requirement.
• Multiple alarm function: compressor time-delay protection, compressor overcorrect protection, water flow alarm and over high / low temperature alarm;
• Specific disconnection alarm securing protection.
• Enclosed water tanks, water used for a long time.
• Equipped with alarm output port, can quickly protect sensitive components.
• High cost performance, low failure rate.
• Multiple power specifications; CE approval; RoHS approval.

Parameters:

Alarm function:

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.

Notice:

Industrial cooling machine’s installation is very simple, the new machine for the first time using, you can install it as following steps.

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

2. Open the injection port to feed cooling water.

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

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

4. 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.

(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, according to different conditions, the time is range from seconds to minutes, so do not turn off the power and again on frequently.

5. Check the water level in the water tank.

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

6. Adjust parameters of temperature controller.

 CW-5000 series use an intelligent thermostat. Normally users do not need to adjust it. If it is really necessary, please refer to “Operating status and parameters adjustment.”

Cautions:
1. Please ensure that the power supply and electrical outlet are in good contact and the earth wire must be firmly grounded! Although the average operating current of the chiller is small, but the instantaneous operating current could be up to 6 ~ 10amps sometimes (The instantaneous operating current of models of AC220V power supply are possible to be up to 10 ~ 15amps).

2. Please make sure there is a 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 200 ~ 250V (110V model is of 100 ~130V). If you do need a wider operating voltage range, customization is available for us.

3. To protect the pump, it’s strictly forbidden to run the chiller without having 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. When the water level is below the green (NORMAL) range of the water level gauge, the cooling capacity of our chiller will go down slightly. Hence please ensure the water level is within the green (NORMAL) range. To drain through circulating pump is strictly prohibited!

 
4. 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.

 
5. The filter screen must be regularly cleaned! It’s essential to unpick and wash the dust gauze, or the serious blockage will cause breakdown to the chiller.

6. Please pay attention to the effect of the condensate water! With greater ambient humidity, when the water temperature is lower than the ambient temperature, the condensate water will generate on the surface of water circular pipes and the cooled components. If above circumstance appears, it is recommended to set a higher water temperature or keep pipes and cooled parts warm.
