1、 The cooling capacity test is based on the condition of ambient temperature 35℃ and water temperature 28℃.Special specifications also can be accepted.
2、 The tube size can be ordered according to customer's requirements.
3、 The performance parameters of water pump are just for reference.
4、 Power supply: Cooling capacity≤6000w(1P~220V/50Hz) ; Cooling capacity≥6000w(3P~380V/50Hz) .Special order also can be accepted.
5、 Temperature settings: 5~45℃ as of fixed-temperature type; indoor temperature±0~9.9℃ as of tracing-temperature type.
6 The refrigerant usually is R22, also can be changed to meet customers’ requirements.
7、 The ambient temperature is less than or equal to 43℃. Please keep the ventilation space of inlet and outlet more than 0.8m. Don’t block the ventilation space.
8、 Please install leakage circuit breaker at the power input terminal.
9、 Above parameters will change along with technical improvement without prior notice and the actual data are subject to the nameplate on the machine.
