Oil coolers are intended to equip power oil transformers, autotransformers and reactors with ДЦ cooling systems.
Climatic design of oil coolers is У, ХЛ, T, location category is 1 by GOST 15150.
ДЦ oil coolers main parameters:
- heat flow at nominal parameters – 180 kW;
- aerodynamic resistance at nominal parameters – 0.32 kPa;
- incoming oil rated temperature – 75 C;
- incoming air rated temperature – 40 C;
- rated parameter of oil temperature exceeding air temperature – 35 C;
- air consumption – 7.5 m³/s;
- incoming oil temperature – from -45 C (-60C for ХЛ design) to +115C;
- incoming air temperature – from -45 C (-60C for ХЛ design) to +45C;
- oil max. operating pressure – 300 kPa.
