During this last ATMOsphere Europe edition held in Barcelona on the 19 and 20 April, 2016, we had the opportunity to participate with the presentation of our R&D Director Vicente Guilabert about low energy consumption in an R290 bottle cooler with variable speed compressor. In this actual case study, the improvement in efficiency has been demonstrated of a bottle cooler when using our propane compressor NLT60FSN, obtaining 39% reduction of energy consumption compared to another standard compressor model NL60TB, also in propane.
