Product Manual
1.The PM and EPM range of SCR screw compressors unique oil cooled permanent magnet
motors offer the highest motor efficiency ratings.
2.SCR’s oil cooled motors utilize the compressor oil lubrication system for cooling the motor
throughout the whole frequency range ensuring the motor temperature remains cool evenat low
speed running. Adequate motor cooling avoids high temperature demagnetization problems often
associated with Permanent Magnet technology. SCR’s PM motor is rated at 180 degrees Celsius
effectively avoiding demagnetisation issues
3.SCR’s PM motor is a fully enclosed IP65 structure, eliminating any dust or liquid ingress.
This protects the motor even in the harshest of environments.
4.The unique PM motor design offers reduced maintenance due to the bearing free motor design.
5.New generation super profile airend SCR’s Super profile airend, reduces air leakage and increases
the compression area, exceeding the national level of energy efficiency by 8%-10%. Due to the excellent
safety performance and high efficiency ratings, this makes SCR’s airend the customers first choice of airend.
6.Original “Morse” connection The airend and motor use a “Morse” connection making any future air end
maintenance convenient and simple to carry out. This method of connection avoids any damage to the motor,
greatly reducing maintenance costs.
7.Touch screen intelligent controller
