Warning: R-407C is a zeotropic blend. Elins Nigeria emphasizes that it must be charged in the liquid phase (invert the cylinder) to ensure the three constituent gases enter the system in the correct chemical ratio.
Market Insight: In the Nigerian HVAC sector, Harp® R-407C is the elite choice for facility managers overseeing shopping malls, hotels, and corporate offices in VI and Ikoyi. Elins Nigeria positions Harp® as the “Safe Retrofit” gas—where unbranded 407C blends often suffer from “fractionation” (gas separation) leading to poor cooling, Harp’s UK-standard purity ensures your central cooling plant runs exactly as the engineers intended. It is the insurance policy for large-scale R-22 to HFC conversions.
Safety Note for : While R-407C is a replacement for R-22, it is not a direct “drop-in.” The system’s Mineral Oil (MO) must be replaced with Polyolester (POE) oil. Elins Nigeria Technical Advice: Because R-407C is a blend with significant temperature glide, if a major leak occurs in the vapor phase, the remaining gas composition may change. In such cases, we recommend a full evacuation and recharge with fresh Harp® R-407C to restore 100% cooling capacity.
