Original DY Brand R22 Refrigerant Gas (13.6kg Cylinder) | 99.9% Pure | High-Performance Grade for Commercial & Residential Cooling
The Industrial Choice for Cost-Effective Cooling: DY Brand R22 (13.6kg)
In 2026, the demand for high-purity, budget-conscious refrigerants in Pakistan is led by DY Brand. Manufactured by the renowned Zhejiang Dongyang Chemical, this R22 refrigerant is specifically refined to provide high-efficiency heat exchange in high-ambient environments. Unlike generic “no-name” gases, DY Brand ensures a consistent pressure-temperature relationship, preventing the high-pressure trips common in Pakistani summer heatwaves.
Why DY Brand R22 is the 2026 Choice for Contractors:
- A-Grade Chemical Purity: Guaranteed 99.9% pure HCFC-22, minimizing the risk of non-condensable gases that lower cooling efficiency.
- Moisture-Free Performance: Advanced dehydration technology ensures zero moisture, protecting your system’s capillary and expansion valves from internal icing.
- Zero Acidity: Processed to eliminate impurities that cause “winding burn” in compressors, extending the life of older R22 units.
- Global Export Quality: DY is a top-tier Chinese exporter, providing factory-sealed 13.6kg (30 lbs) cylinders that meet international AHRI standards.

Verification Guide 2026: To ensure you are receiving the Genuine DY Brand and not a local repacked cylinder:
- Holographic Label: Genuine DY cylinders feature a distinct factory hologram near the valve. Check for color shifts when tilted.
- Factory Seal: The valve should be covered with the original DY-branded shrink wrap. If it’s plain or missing, the gas may be under-weight or contaminated.
- Cylinder Embossing: Look for “DY” or factory marks embossed on the shoulder of the cylinder.
- Tare Weight Consistency: Always weigh the cylinder. A genuine DY cylinder must equal Tare Weight (TW) + 13.6kg.
