There will be thermal deformation when the machine is in the procession so that the machine will less precision.In order to avoid the problem,HERO-TECH specially designs and develops the HTO series chillers for cooling the oil. At present, the chiller is widely used in CNC manufacturing plants ( CNC planar grinder, CNC rapid lathe, CNC oil-hydraulic machine, CNC water engraving machine ) ,electro discharge machining plant.

 Note: 1. nominal cooling capacity is according to:
               Inlet chilled oil temperature: 25℃
               Outlet chilled oil temperature: 20℃
               Inlet cooling air temperature: 30℃
               Outlet cooling air temperature: 38℃
          2. working Range:
              The temperature range of chilled fluid is from 20℃ to 50℃;
              Temperature difference between inlet and outlet chilled fluid is from 3℃ to 8℃.
              The machine can be used while the ambient temperature is below 35℃.
             We can offer customized chillers if the oil temperature required is below 20℃.      
             We reserve the right to modify the above dimensions or parameters without further notice.
