ODF rotary screw air compressor's screw rotor (all-end) is imported from German, which is the third generation rotor, featuring asymmetric shape with a gear ratio of 5:6 and a reasonable ratio between length and diameter. Meanwhile, our rotor owns a tangential speed of 30-36m/s, far less than that of traditional air compressor – about 60m/s. Besides, rotors always enjoy a clearance of 0.003inch, so no abrasion will occur. Besides, a small difference between different teeth helps to reduce the return loss. Not only that, since it increases 10% ~12% of efficiency than air compressor with a gear ratio of 4:6, 20% of electricity could be saved. Besides that, SKF bearing from Sweden is also introduced to prolong our all-end's service life.
1. Switching value: 3 channel input and 5 channel output;
2. Simulation: 1 channel temperature input with Pt100 platinum resistance temperature device (RTD), 1 channel signal input with 4~20mA sensor transmitter, two sets of three-phase current input ( Supportive to CT (current transformer)).
3. Power supply of controller: AC20V 40AV;
4. Available ranges:
a. Oil temperature: -20~150℃;

c. Working hour: 0~999999 hours;
d. Current: 0~999.9A;
e. Pressure: 0~999999
5. Phase sequence: When the protector analyzes the error in terms of phase order, a protection for motor will be activated;
6. Protection for motor: Controller allows a protection for main motor and fan motor when followings occur: blocking, short circuit, default phase, unbalance, overload and etc.
7. High temperature protection: When actual temperature is higher than set temperature, the protection will be activated.
