Davide Refosco - Nature and technology working as one
PDF document
published on 17 March 2015
Davide Rofosco outlined SCM Frigo’s product evolution from producing subcritical rack systems (2005) to the latest Plug’n Cool booster range (2013), and transcritical and NH3 indoor systems (2014). SCM already has 20 Plug’n Cool systems installed throughout Europe and Refosco explained that parallel compression had increased efficiency by 15%. SCM’s focus in 2015 will be to continue to develop the efficiency of its booster system to push the CO2 equator southward.

Sergio Girotto - Enex - leading in refrigeration
PDF document
published on 17 March 2015
Reliability, efficiency and cost of CO2 commercial refrigeration systems were the focusses of Sergio Girotto’s presentation. Designed for ‘overfeeding’, ENEX has been developing a unit with auxiliary compressors since 2008 to be specifically suitable for southern climates. More than 20 of the 60 systems have been installed with an ejector design and consume 25-30% less of standard CO2 solution in a typical southern climate.

Micael Antonsson - Refrigeration market trends
PDF document
published on 17 March 2015
Micael Antonsson of Green & Cool presented cost effective and reliable solutions for hot climates and touched on cost efficiency in smaller store formats. In particular, he highlighted Green & Cool’s installation of a refrigeration system from its CO2VINPACK range to replace 5 outdoor condensing units at a store in the UK, concluding that it provided 60kW of cooling capacity and proved an effective solution in the CVS layout, reducing energy costs by 80% in 6 months.

Jürgen Süß - Natural water
PDF document
published on 17 March 2015
In his presentation, Jürgen Süß extolled the virtues of water as the ‘perfect refrigerant’, including its low environmental impact, chemical stability as a working fluid and high COP. Displaying efficient energy’s eChiller, with two-stage compressor modulation and a very high COP of 26, the unit requires only 200-300W electrical power to operate at an ambient temperature of 14°C in a free cooling mode.
