Natural refrigerants will become more and more popular over the next 12 years as HFC refrigerants are phased out. Carbon dioxide/ R744 was one of the first refrigerants. As modern technology is evolving, this refrigerant is becoming more and more efficient in higher ambient temperatures. It uses a transcritical gas cooler to reject the heat in the high side; there is still enough latent heat in the low side to make it an effective refrigerant. Booster packs have low temperature compressors that feed your -20° cabinets and medium temperature compressors that feed your 2-5° chilled cabinets. We are adept in the sensitivities of working on high pressure systems. Our skilled engineers know how to prevent the sublimation of the refrigerant when breaking into the system
