The machine design is easy to understand and convenient to control.
Control operation with a single on/off button, send an alarm when an abnormal event is detected, and quickly reset the system.

- Power light
- Warning light
- Remote control signal
- Anti-ice mode
- Forming Up Mode
- Separate water pump installation
- Self-reset system after power failure, etc.
Large water pipe in the tank, convenient for cleaning. There is an LED display showing the water level clearly.
The water tank has a maximum diameter of 100 mm.
Easy to clean!
But it also reduces the rate of leakage or errors in water level control very well. There is an LED screen to clearly show the water level.

Easy to clean

It shows the water level clearly.
There is a standard filter to prevent clogging in the pipe.
There is a standard filter to prevent clogging in the pipe!
The filter can be removed for easy cleaning.
Cleaning the filter will reduce the damage rate of the cooling unit.

*1 The achievable pressure level at a cold water temperature of 20℃, an outdoor temperature of 32℃, and a capacity of 95% may be affected by heat generated during operation.
*2 Try to control the current so that it does not fluctuate beyond the specified value of ±3%.
*3 Maximum current at full load.
*4 Use the machine continuously and the load does not exceed ±10% and the current is constant, except when the machine is heavily loaded when starting operation.
*5 Install a standard circuit breaker (NFB) in the machine.
*6 Measure the noise level at a distance of 1 meter in front of the machine and 1 meter above the machine.
Warning 1) This chiller uses ethyl alcohol with a concentration of 30-40%, which contains pure brine (Aurora Brine) for Z-1
Or must use pure water 1µS/cm as a conductive medium. If using ethyl alcohol with a concentration lower than 30-40%, the cooling efficiency will decrease by about 10%.
Warning 2) The power generated by the heat (kW) is about 1.3 times of the power generated.
Warning 3) The working environment may cause the liquid in the pipe to freeze. Please install special equipment such as welding pipe, drain pipe.
