Our R404A is a zero ozone depletion (ODP) hydrofluorocarbon (HFC) refrigerant blend. R404A is a ternary blend of R125, R143a and R134a (44%/52%/4%). It has been formulated to closely match the properties of CFC R502. It is widely used in new equipment that would have previously used R502 and can with specific modifications be retrofitted into exiting R502 equipment.

Applications

Cold-Storage Cells
Supermarket Display Cases
Ice Machines
Replacement for R502 in Transport Refrigeration
Retrofit of Existing R502-Installations with R404A is Possible

Lubricant Recommendation

POE lubricants must be used with R404A since it is not miscible with mineral or alkyl benzene lubricants found in most old R502 systems. When retrofitting, a lubricant flushing procedure is necessary to reduce the original oil content below 5%. For refrigeration systems using an oil separator, multiple oil flushes may not be required. New R404A equipment will be charged with the OEM recommended lubricant, ready to use with R404A.

Charging

Charging with Gas UK R404A can be done either as a vapour or a liquid.

Properties and Performance

R404A is designed to meet the needs of many new and existing refrigeration systems. R404A is a zeotropic HFC refrigerant blend rated A1 by ASHRAE (lowest levels of toxicity and flammability), having zero ozone depletion potential and a Global Warming Potential of 3922.
