Refrigerant Gas and Accessories

Refrigerant gas and associated accessories are essential service consumables and components for the commissioning, maintenance, and repair of all vapour-compression cooling systems. Refrigerant selection is governed by the system design specification — R-410A and R-32 for modern split and VRF systems, R-134a for centrifugal chillers, R-407C and R-22 (phase-out compliance) for legacy plant, and next-generation low-GWP refrigerants (R-1234yf, R-513A, R-454B) for new designs targeting F-Gas and Kigali Amendment compliance. Accessories include refrigerant recovery cylinders, manifold gauge sets, vacuum pumps, electronic leak detectors, flaring and swaging tool kits, service valves, filter-driers, sight glasses, and charging hoses rated for the applicable working pressure. Proper refrigerant handling requires certified technicians following ASHRAE 15, EN 378, or local QCVN safety standards to prevent accidental release, cross-contamination, and moisture ingress. We supply genuine refrigerant gases and quality-verified accessories to support both new installation works and ongoing preventive maintenance programmes.
