R407c Refrigerant Technical Bulletin #R-100 - DXairRefrigerant: R410a vs. R407c There are some dehumidification systems manufacturers using R407c refrigerant vs. the industry standard R410a. We occasionally receive calls from engineers and contractors inquiring what the difference in the two refrigerants are and how they affect the costs and operation of dehumidification systems.
R-407C - Refrigerants• R-407C can be added to a system during servicing, if required, without recovering the existing R-407C charge. Verify system performance. If the system has a critical charge, however, it is recommended that any remaining refrigerant be removed prior to servicing. • This refrigerant blend must be removed from the cylinder as a liquid.
New Refrigerant 407C - Neil OrmeRefrigerant Charging. In general, refrigerant charging equipment such as charging boards, valves, and hoses, which are compatible with R22 should be compatible with R407C. Refrigerant charging equipment needs to be recalibrated for use with R407C. Once designated for R407C use, it should be used specifically for that refrigerant only.

Comparison of R-407C AND R-410A with R-22 in a 10between the air and refrigerant side were within 1% to 2% for R-22 and within 4% to 5% for R-407C and R-410A. It is believed that the larger discrepancies in the energy balance for R-407C and R-410A are related to uncertainties of the refrigerant properties. The cooling and heating capacities reported in this paper were
