refrigerant which enables compact system dimensions. The 8-cylinder reciprocating compressors for transcritical CO2
applications
are also around 10 per cent more energy- efficient than the smaller 6-cylinder compressors currently available on the market, which reduces energy consumption and emissions. Designed for frequency inverter operation, the Bitzer 8-cylinder CO2
reciprocating
compressors are available in two motor variants with displacements between 69.4 and 99.2 m3/h. They are also equipped with start unloading as well as with VARISTEP mechanical capacity control for part load operation.
The 8-cylinder CO2 reciprocating
range with up to 6.5 kW in low temperature application and up to 25 kW in medium temperature application. The LHL3E, LHL5E and LHL7E condensing units are approved for use with refrigerants of the A1 and A2L safety groups and can therefore be used in a variety of both low and medium temperature applications across all climate zones – with a single device. One example is cold stores at petrol station shops or fast-food restaurants. The Ecolite LHL7E continues the plug- and-play concept, allowing users to quickly install any Ecolite model. The system can be commissioned via the user-friendly control with display or in combination with the Bitzer BEST software. Designed to ensure access to all the components, the condensing units simplify commissioning and maintenance and are robust, compact and quiet. The semi-hermetic Ecoline reciprocating
compressors with VARISTEP mechanical capacity control ensure efficient, flexible and reliable operation of condensing units in part and full load. For another boost in system efficiency, the Ecolite LHL7E offers optional heat recovery – a must for modern system concepts.
Digital solutions such as the Bitzer BEST
software allow users to configure and monitor Ecolite condensing units, with further digital services available via the Bitzer Digital Network (BDN).

capacity for large systems and heat pump applications – with fewer compressors than before: the new 8-cylinder reciprocating
compressors for transcritical CO2 applications enhance the Ecoline CO2
series
for even larger capacity ranges with CO2 as a refrigerant in refrigeration and heat
pump applications. Bitzer developed the compressors for systems with a larger capacity range which were once developed for use with HFC refrigerants and ammonia. The benefits of CO2
in larger systems for
commercial refrigeration and industrial applications: it’s a natural, non-toxic
compressors boast low gas pulsations, vibrations and starting currents. Improved gas guidance minimises internal pressure drops, whilst the oil carry over rate achieves the low values typical of Bitzer. Thanks to the IQ module and OLM oil management, the compressors are easy to integrate, install, operate and service. Bitzer, which specialises in refrigeration, air conditioning and heat pump technology, has sold more than 270,000 CO2
compressors
since 2003, primarily for commercial refrigeration systems, and that number is only growing. Demand is also on the rise for transport, heat pump and industrial applications. The new, variable Bitzer ejectors for CO2
applications are suitable for the 8-cylinder CO2 reciprocating compressors and fulfil the most stringent requirements.
