LU-VE Group : Pioneer in natural refrigerants

Ahead of the market since 1986, LU-VE Group has adopted policies of avantgarde research and development and respect for the fundamental principles of environmental protection: reduced energy consumption, reduced use of refrigerant fluid, low noise levels, high reliability over time, reduced dimensions.

LU-VE Group was amongst the first to focus on the replacement of FGases (fluorinated greenhouse gases), ahead of the market, which today increasingly focuses on the use of natural refrigerants (CO2, hydrocarbons, and ammonia) with low or no impact on the ozone layer or greenhouse effect. LU-VE Group has a wide range of Commercial and industrial unit coolers and condensers, optimized for the use of natural refrigerants.

In the case of CO2, the new challenge is to shift the “CO2 equator” and make this technology efficient even in countries where it was not possible before. LU-VE Group is at the forefront also in this case. Together with international institutes and universities, it is collaborating with the United Nations Industrial Development Organization (UNIDO) to increase the use of natural fluids, replacing those with a greenhouse effect. To this end, pilot plants have been built in India and the Middle East, in areas where it was thought that the climatic conditions made it impossible or extremely difficult to use CO2.

Since 2004, through challenging research projects on new refrigerants, LU-VE Group boasts a track record of first highly successful transcritical CO2 installations in Europe, Latin America, the Middle East, and Asia..

Already in 2004, well ahead of the market and the current “green wave”, the Group had produced the SHVDT 696 – CO2 gas cooler, on behalf of Linde, one of the major international manufacturers of refrigeration systems, destined for the Coop Supermarket, Tägipark Wettingen (Zurich, Switzerland). The fulfilment of the project was the result of a complex study, developed in collaboration with the Politecnico di Milano, which involved the adoption of unusual technical solutions and choices in the field of refrigeration.

In 2018, LU-VE has been the first supplier of a CO2 gas cooler to operate in the in the Gulf Region, for the Carrefour Hypermarket in Masdar City, Abu Dhabi, where the ambient temperature can reach up to 51 °C. The gas cooler for trans-critical use has been carefully studied along with Epta Refrigeration, to withstand the harsh weather conditions of the Arabian Peninsula. The product features state-of-the-art solutions and manufacturing techniques, such as:

• Low energy consumption EC fans;

• Adiabatic spray system;

• Al-Mg alloy fins with coating;

• Fully controlled and BMS connected regulation system;

The system has turned out to be extremely energy efficient, with an energy saving of 40% compared to traditional R404a based ones, installed in the Abu Dhabi area.

In 2000, LU-VE was the first company in Europe to obtain Eurovent’s then new “Certify All” certification, for all ranges of condensers, dry coolers and unit coolers.

In the twenty years since then, LUVE products have passed all the laboratory tests required by the certification procedure, which provides for an annual verification of some models of the ranges, chosen by Eurovent as samples, and tested at specialized international institutes. In 2016, LU-VE was the first manufacturer for which Eurovent officially certified that their heat exchangers for refrigeration had never registered a single negative test during three different test cycles.

At the end of 2020, LU-VE Group was amongst the very first companies to obtain Eurovent certification (No. 00.10.214) for CO2 unit coolers (thermal capacity, sound level and energy consumption), marketed under the brands LU-VE Exchangers and AIA LU-VE.

Eurovent certification, the first of the series explicitly dedicated to unit coolers using CO2 as the refrigerant fluid, is the culmination of a journey that has seen LU-VE be “first mover” in this field.
