DeCO2ded: Understanding ROI on CO2 Refrigeration Systems
DeCO2ded: Understanding ROI on CO2 Refrigeration Systems Here s the question many grocers ask when they re considering retrofitting or replacing commercial refrigeration systems: How much will it cost
Due to its low temperature glide about 1.5 approx. (75% less than R-407C and R-427A), it is suitable for a wide range of applications.
TECHNICAL DATA SHEET R434A () Features and uses of R-434A () is a non-flammable HFC mixture. ODP = 0, compatible with traditional mineral lubricants, alkyl benzene and also with synthetic POE, so there
