When the temperature controller of nanosecond laser water chiller unit displays E1 error code, that means ultrahigh room temperature alarm is triggered. In most situations, this is because the location of the nanosecond laser water chiller unit has poor supply of air. Therefore, to avoid this alarm, users need to make sure the location of the nanosecond laser water chiller unit is well ventilated and the ambient temperature is below 40 degree Celsius.
After 18-year development, we establish rigorous product quality system and provide well-established after-sales service. We offer more than 90 standard water chiller models and 120 water chiller models for customization. With cooling capacity ranging from 0.6KW to 30KW, our water chillers are applicable to cool different laser sources,laser processing machines, CNC machines, medical instruments, laboratory equipment and so on.
