ER 22-25 Series screw compressors

1. Direct reliable transmission without energy loss

The "air end" compressor and the motor are directly united by means of a carcass where the elastic coupling is located. This type of assembly is the most adequate because:

• It eliminates the losses of transmission that are produced in belt systems.
• It guarantees the perfect alignment of the compressor with the motor.
• It does not require maintenance.
• It reduces vibrations of the rotor which lengthens the life of the bearings.

2. High-efficiency rotor

ER- 22-55 series uses rotors with new design 5/6 with the new SRM "D" profile, it means significantly improve the performance of traditional rotors 4/6.

Machined with high-precision machines have reduced the clearances inside the rotor.

3. Integrated air-oil separator = maximum efficiency without leakage

The oil separator exclusive design is made up of a deposit that inside there are several elements that cause the first separation of oil from air.

The top is a special piece that acts as a cap, and includes filters and control elements, without interconnecting piping thereby eliminating leaks and easy maintenance.

4. BETRONIK-II. Accuracy and optimal performance.

The electronic control BETRONIK-II, is a rugged industrial microprocessor specially developed for maximum efficiency and protection of the compressors.
