Refrigerant Scales & Charging Equipment for HVAC Engineers

Digital refrigerant scales, charging stations, refrigerant analysers, and A2L/A3 recovery machines for accurate refrigerant handling and F-Gas compliant system charging. Mastercool scales and charging equipment in stock with same-day UK dispatch and trade pricing.

Digital Refrigerant Scales

Accurate refrigerant charging by weight is essential for R410A and R32 systems — overcharging or undercharging directly affects system efficiency, compressor life, and warranty compliance. The Mastercool Accu-Charge II electronic refrigerant charging scale delivers high-precision weighing for professional charging work. The 98202 and 98201 5000g scales are specifically rated for R600a and R290 flammable refrigerants — essential for A3 refrigerant handling. Use scales alongside manifold gauges for complete charging control.

Refrigerant Analysers

The Mastercool Legend Series R1234yf & R134a Refrigerant Analyser — available with Bluetooth connectivity — identifies refrigerant purity and contamination before recovery or recharge. Refrigerant analysis protects recovery equipment from cross-contamination and ensures correct refrigerant handling on next-generation systems.

A2L & Combustible Gas Recovery Machines

Mastercool spark-free Twin Turbo recovery machines for safe handling of A2L flammable refrigerants including R32 and R1234yf, and A3 refrigerants including R290 and R600a. The 69400 Mini Spark-Free and 69395 ATEX certified units are engineered for flammable refrigerant recovery where standard recovery machines cannot be used safely. Browse all recovery machines including standard dual-voltage units.

System Flush Kits

Mastercool A/C system flush kits for removing contamination from refrigerant circuits following compressor burnout. Flushing is required before installing a replacement compressor to prevent acid and debris from damaging the new unit. Use with refrigeration oils to recharge the system with the correct oil grade after flushing.
