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 even at low speed running. Adequate motor cooling avoids high temperature
demagnetization problems oftenassociated with Permanent Magnet technology. SCRs
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
