There’s a good reason why CO2 is the refrigerant of choice for supermarket applications: it’s future-proof whilst offering high energy efficiency and low global warming potential. ALDI SÜD came to this conclusion back in 2006 and thus began consistently switching its refrigeration systems at its stores to the environmentally friendly refrigerant. 1,400 stores have since been equipped with reciprocating compressors for transcritical CO2 applications. Erik Bucher, Director of Refrigeration Sales at BITZER in Sindelfingen, was recently able to present the 100,000th CO2 compressor produced by BITZER in Schkeuditz near Leipzig to ALDI SÜD. ‘We’ve maintained a long-standing partnership based on trust with ALDI SÜD,’ says Bucher. ‘I can confidently call our customer a pioneer, as they are also partly responsible for the fact that installations with CO2 as a refrigerant are now one of the most common standards in the EU.’

Jens Straßburg, Director Store Operations Management Refrigeration at ALDI SÜD, says: ‘We’re always on the lookout for solutions that will allow us to operate our display cabinets and refrigeration systems more efficiently, reduce greenhouse gas emissions by using the right refrigerant, and minimise our impact on the environment.’ ALDI SÜD’s activities are shaped by long-term, sustainable thinking. ‘We’ve dedicated ourselves to operating with a focus on the future,’ Straßburg adds. ‘Even if that means we have to invest more for a certain period of time. However, energy savings ultimately serve as proof of a short amortisation period and high investment security.’
The high energy efficiency of BITZER reciprocating compressors for transcritical CO2 applications makes it possible. Designed for operation with frequency inverter, they offer flexible, efficient and stepless capacity control. This is particularly important when it comes to the capacity characteristic of CO2 systems: stepless capacity control can minimise suction pressure fluctuations and cycling rates, which in turn reduces energy costs and increases the life cycle. It can also boost the quality of the products requiring cooling and the cooling process.
‘We highly value BITZER as a partner – particularly in this day and age, when there are so many changes and so much is going on in refrigeration.’

‘We’re looking forward to continuing to work closely with ALDI SÜD in the years to come,’ says Erik Bucher. And Jens Straßburg adds: ‘We highly value BITZER as a partner – particularly in this day and age, when there are so many changes and so much is going on in refrigeration. We need a partner we can rely on with decades of experience, to ensure our operations are more sustainable in the future.’
ALDI SÜD receives the Deutscher Kältepreis 2018
From the hands of Federal Environment Minister Svenja Schulze ALDI SÜD received the Deutscher Kältepreis 2018. The company earned the second place in the category “Intelligent Monitoring of Refrigeration and Air-Conditioning Systems” and was awarded the prize for its efforts to identify and minimize conspicuous energy consumption and refrigerant emissions with the help of monitoring.
