Cooling Method

Water -Cooled(Cooling system)

Installation Site

• Work station ground should be flat, good ventilation; no flammable article, corrosive gas or dust.

• No strong electromagnetic radiation source nearby

• Close to drainage system ( within 2 meters for condensate water)

• The ground bearing capacity not less than 15000kg/m2

• Prepare proper power supply and water supply

• If need water or gas supply, should be equipped with in advance

• Ambient Temp: 5℃~25℃suggested, 25℃~35℃ function well;(for air-cooled model);5℃～40℃ function well (for water-cooled model)

• Ambient Humid:≤85%RH

• Ambient Pressure:86KPa～106KPa

• Installation space assurances, as following

  ​

​

Cooling Water

Water temperature: 5℃≤ water temp.s ≤28℃.If the source of water is air conditioning chilled water, it’s temp is lower than 10℃ ,need to take some measures preventing pipe condensing water.

1.If adopt the design of the air cooling, do not need water.

2.If user need build new cooling water circulation system.Cooling tower standard

≥10tons, or Water chiller refrigerating capacity≥35KW(20℃).

3.Cooling water system :GB50050-1995

Water flow:≥ 10 tons/hour

Pipe diameter:G2.5 inch ×2

Inlet water pressure:0.3MPa～0.6MPa

water pressure difference inlet and outlet:≥0.2MPa

Water request: meet standard GB50050-1995

Temp Test

Temp.Range:-70℃～＋180℃

Note:1.Test with no load, meeting GB/T5170-2008,if no other special notice.

2.Ambient Temp 25℃, good ventilation condition: function well if 35℃≥RT＞25℃;Cool down rate and thermal load capacity will be affected by ambient low temperature.
