Standard Refrigerant - ECOLINE
The BITZER ECOLINE series is the most universal compressor in the range of semi-hermetic reciprocating compressors. It combines high efficiency, a wide range of applications, flexibility in refrigerant selection, smooth running, solid design and high reliability. Highlights: Outstanding efficiency in wide application range | Reliable design/well-known BITZER product | Enhanced application limits | Optimal internal gas flow | Very compact design
Standard Refrigerant - ECOLINE Tandem
Tandem compressors are the simplest way of connecting two compressors in parallel. Turning on and shutting off one compressor allows for a particularly effective graduation of output. The 4- and 6-cylinder models can also be equipped with capacity control systems (cylinder cut-off), allowing them to run with up to four or six levels of output. Particularly for applications with high load fluctuations, this allows for cost-effective and energy-efficient operation under full- and part-load with all conventional refrigerants

Subcritical CO₂ Applications - OCTAGON SL Subcritical
The OCTAGON SL series is a closely stepped range of models with a cooling capacity ranging between 2.7 and 80 kW (–35° C/–5° C) for subcritical CO₂ applications. Alongside its well-known attributes, this SL compressor series also offers improved energy efficiency. In addition, the application limits were pushed to a higher condensing temperature, whilst the admissible pressure load was expanded on the high and low pressure side (53/30 bar) | Additional strengthening of housing and drive gear | Specially adapted motors for condensing temperatures of up to 15 °C | Reduction of internal flow losses
Subcritical CO₂ Applications - ECOLINE ME Subcritical
The subcritical ECOLINE ME series combines high standstill pressures, high efficiency, smooth running and high reliability in combination with the natural refrigerant CO₂ Applications | Medium temperature | Low temperature | Industry sectors | Commercial refrigeration | Marine
Transcritical CO₂ Applications - ECOLINE Transcritical
Expanded capacity range | New models with up to 38.2 m³/h | Housing with pressure strength and no bottom plate | Maximum allowable pressures: High pressure side up to 160 bar : Low pressure side down to 100 bar | Wear-resistant drive gear with advanced multi-layer bearings | High energy efficiency | Suction gas-cooled motor | Particularly efficient working valves, special drive gear geometry | Cylinder heads with separate, thermally insulated high and low-pressure chambers | Wide application range | Transcritical and subcritical operation modes possible | Two, four and six-cylinder configurations | Quiet and low vibration | Optimal for operation with a frequency inverter designed to control capacity | Low oil carry over thanks to centrifugal lubrication
Hydrocarbons - ECOLINE P Series
BITZERs ECOLINE P Series is specially adapted for operation with Hydrocarbon refrigerants. It combines high efficiency, smooth running, a wide range of applications, flexibility in refrigerant selection, solid design and high reliability
R410A - OCTAGON R410A Series
OCTAGON compressors for the high pressure refrigerant R410A. Designed for medium and high saturation suction temperatures in an extended normal temperature refrigeration range and high temperature range, even under high ambient temperatures. Efficient capacity control thanks to blocked suction | High efficiency working valves | Advanced centrifugal lubrication system with oil centrifuge | Wear-resistant drive gear with advanced multilayer bearings | Housing with high strength pressure and no bottom plate for operating pressures of up to 42 bar on the high pressure side
