Semi-Hermetic Ecoline Compressor
The Semi-Hermetic Ecoline Compressor from BITZER is the creative advancement of the proven, robust and powerful semi-hermetic reciprocating compressors from BITZER.
The Ecoline compressor is a combination of high efficiency, smooth running, a wide range of applications, and flexibility in refrigerant selection, solid design and high reliability.
- 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.
- 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.
- 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
Open Drive Compressor 2nd Generation
With the open drive design, standard motors can be attached to the compressor via coupling housing or belt drive. The Open Drive compressor is reliable with easy maintenance.
- Suitable for coupling and belt drives
- The flange surface on the side of the shaft duct enables the direct extension of the motor (IEC B3/B5) by means of a coupling housing (accessory)
- The lightweight design and careful balancing of the moving mechanical parts result in extremely smooth running
- The surface-hardened crankshaft, optimised piston form and chromium-plated compression rings guarantee low frictional losses and a long service life
- Highly efficient and robust valve plate design resulting from a new style of valve construction – Equipped with proven design elements
- Pressure oil lubrication with reversible gear pump
- The special oil return system results in extremely low oil carry over
- Cooled shaft seal by means of pressure oil rinsing and suction gas circulation, resulting in low thermal loads and excellent stability
- Low-friction aluminium pistons
- Exchangeable bearing bushes (from type IV[Y])
- Reliable oil supply with centrifuge lubrication
- Hard-chrome-plated pistons (from type IV[Y])
- Special wrist pin bearing
- Extremely resistant against liquid slugging thanks to the robust design and low speed
