Electronically controlled silicone oil "220V AC Cooling Fan" can achieve more accurate and rapid response. Reduce system noise and saving energy consumption than similar temperature sensitive products have improved significantly. Can improve fuel consumption, reduce engine power loss of 6% -10%. And this brings Borg Warner electronically controlled silicone oil "220V AC Cooling Fan" fan is optimized, an upgrade of 8% and 7% static pressure air flow efficiency, which can effectively reduce engine temperature 3 degrees Celsius. For overseas electronically controlled silicone fan who has been very wide application, technology is relatively mature. However, China is still in its infancy, due to price many users can not accept, Borg Warner also designed according to the situation of ordinary silicone localization clutch "220V AC Cooling Fan", the principle of controlling the fan speed in response to the test in accordance with the intake air temperature sensor excitation , not be controlled by the ECU. This is compared to the last fan technology has greatly improved.
