Why Refrigerant Recovery Is Legally Required
Under UK F-Gas Regulations, it is illegal to vent R134a or any other fluorinated refrigerant to atmosphere. Before any work that involves opening a refrigerant circuit — including component replacement, decommissioning or system transfer — the refrigerant must be recovered into an approved recovery cylinder.
Equipment Required for R134a Recovery
- Recovery machine: Purpose-built unit rated for HFC refrigerants
- Recovery cylinder: Dedicated DOT or EN 13322 compliant cylinder — never use a refrigerant supply cylinder for recovery
- Manifold gauge set: Compatible with R134a fittings
- Electronic scales: For weighing recovered refrigerant
- PPE: Safety glasses, insulated gloves
R134a Recovery Procedure
- Connect recovery machine to system high and low side ports
- Start recovery machine in push-pull mode for faster extraction
- Continue until system pressure reaches -1 bar (gauge) or manufacturer-specified level
- Record weight of refrigerant recovered in logbook
- Seal recovery cylinder and label with refrigerant type and weight
- Send full recovery cylinders to an approved reclaim facility
R134a in UK Applications
R134a remains widely used in commercial refrigeration cabinets, ice machines, water chillers and automotive air conditioning systems. Our R134a 13.6 kg cylinders supply engineers for top-up and recharge work after recovery. Browse our full refrigerant range for all common HFC gases.
