LU-VE has over 13 years of experience in CO2. It participated in the construction of the first transcritical supermarket in Europe (2004), providing gas coolers with a spray system in transcritical operation. In 2010, LU-VE decided to invest in CO2, designing the first test plant in Europe dedicated to the heat exchangers.
As with CO2, LU-VE has developed and applied innovations it the NH3 field, introducing in 2005 a new range of unit coolers for NH3 with optimized design with very low internal volume.
In 2016 the new EMERITUS® technology was introduced, bringing together the benefits of spray systems and adiabatic pre-cooling. When EMERITUS® is applied to CO2 gas coolers, high system COP can be achieved even during the hottest hours of the year. This means that the “CO2 equator” can be redrawn, extending the geographical area where transcritical systems can be cost-effectively constructed. Applied to NH3 condensers, EMERITUS® can reduce the internal refrigerant charges by over 50% compared to an evaporative condenser.
