Market Insight: In Nigeria, the “Orange Cylinder” from Harp® is synonymous with “Industrial Reliability.” For businesses managing millions of Naira in frozen stock—from seafood warehouses in Apapa to luxury supermarkets in Victoria Island—Elins Nigeria positions Harp® as the mandatory choice. Using UK-made Harp® gas prevents the moisture-acid buildup in POE oil that is the primary cause of walk-in freezer compressor burnouts in our humid climate.
Safety Note: R-404A must never be mixed with air for pressure testing; use Dry Nitrogen for leak detection. Because R-404A systems use POE oil, which is highly hygroscopic (moisture-absorbing), Elins Nigeria recommends replacing the filter drier every time the system is opened for service. Always verify that your recovery equipment is specifically rated for R-404A high-pressure mixtures.
