Technical Specifications:
1. Model number specification:e.g. HN-YL210P-D, “HN” indicates company code, “YL” indicates oil chiller, “210” indicates refrigerating capacity 210KW, “P” indicates built-in pump, “D” indicates dual system ( two compressors), “T” indicates three compressors, “F” indicates four compressors.
2. * Compressor Power: *2 indicates two compressors working and two separate cooling system.
3. Nominal cooling capacity calculated according to:Ambient temperature: 35℃. Oil inlet flow temperature: 35℃. Oil outlet flow temperature: 30℃. Oils: ISO Vg46.
4. The oil suction inlet must be connected with rigid tube, and it's necessary to install filter. Meanwhile, it's prohibited to install valve on the oil outlet.
5. The length of oil suction tube should not be more than 1.5meters; Otherwise, the diameter of oil suction inlet must be increased.
6. Working range: Oil temperature ranges from 15℃ to 50℃. Temperature difference between inlet and outlet oil is from 3℃ to 8℃. It is better to run the oil chiller while the ambient temperature at or below 42℃; Otherwise it's necessary to use high temperature models.
7. We reserve the right to revise the above information without prior notice.
