Full cooling 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.
commercial refrigeration and industrial applications
The benefits of CO2 in larger systems for commercial refrigeration and industrial applications: it’s a natural, non-toxic refrigerant that enables compact system dimensions.
The 8-cylinder reciprocating compressors for transcritical CO2 applications are also around 10 percent more energy-efficient than the smaller 6-cylinder compressors currently available on the market, which reduces energy consumption and emissions.
variants with displacements
They are also equipped with start unloading as well as with VARISTEP mechanical capacity control
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.
easy to integrate, install, and operate
The 8-cylinder CO2 reciprocating compressors boast low gas pulsations, vibrations, and starting currents. Improved gas guidance minimizes internal pressure drops, whilst the oil carry-over rate achieves the low values typical of BITZER.
Due to the IQ module and OLM oil management, the compressors are easy to integrate, install, operate, and service.
BITZER ejectors
BITZER, which specializes 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 fulfill the most stringent requirements.
