4FE-25Y Refrigeration Compressor 25HP AC Power Source High Efficiency Profile

The advantage of the compressor:

Energy efficient

High-efficiency profile

Infinite or closely stepped capacity control

Optimum economiser operation

Universal

R134a, R407C and R22 (R404A, R507A upon request)

With and without economiser (ECO)

Flexible

Dual capacity control

Changeable between 4-stage and infinite capacity control-without retrofitting the compressor

Suction and discharge gas connections can be rotated in 90" increments

1) New valve plate design

• New geometric concept for pressure valves – for low rear expansion.
• High cooling capacity with minimal energy requirements.
• The ECOLINE cylinder head system: Flexible operation in tandem.

2) Motor

• Efficient under full- and part-load thanks to its broadband characteristics.
• The universal refrigeration compressor: Motor version 2 for medium and low temperature applications.
• Motor versions 1 and 3 for special applications.

3) Capacity control

• The CRII system – intermittent blocked suction For example, 4-cylinder compressor with CRII on both heads: Range of control from 100% to ~10%
• ECOLINE VARISPEED – built-in frequency inverter

4) Downward compatible

• Essential internal components completely redesigned.
• Outer contour as standard: Every ECOLINE is downward compatible
