R22 HVAC Tools & Legacy System Equipment

Professional tools and equipment for R22 (HCFC-22) refrigerant systems. Whilst R22 is being phased out globally, millions of existing HVAC systems still require service, maintenance, and refrigerant recovery with proper R22-compatible equipment.

R22 Phase-Out Status

R22 is being phased out due to its ozone depletion potential:

• EU ban: Production and import banned since 2010 (virgin R22)
• UK status: New R22 installations prohibited, existing systems can be serviced with reclaimed refrigerant
• Reclaimed R22: Available for servicing existing systems
• Recovery mandatory: All R22 must be recovered, not vented
• System lifespan: Many R22 systems still operational and require ongoing service

R22 Compatible Tools & Equipment

Manifolds & Gauges

Pressure gauges and manifold sets calibrated for R22 refrigerant:

• Pressure scales showing R22 saturation temperatures
• Standard 1/4" SAE fittings for universal compatibility
• Digital and analogue options available
• Suitable for R22 diagnostics and charging

R22 Recovery Machines

Professional recovery equipment for R22 reclamation:

• Mandatory for R22 service: Venting R22 is illegal
• High-efficiency recovery: Reclaim R22 for reuse or proper disposal
• DOT-approved cylinders: Store recovered R22 safely
• Compliance essential: Meet environmental regulations

Leak Detectors

Electronic leak detectors calibrated for HCFC refrigerants:

• Sensitive to R22 and other HCFC gases
• Essential for locating leaks before recovery
• Prevents refrigerant loss during service
• Helps identify systems requiring repair or replacement

Vacuum Pumps & Charging Equipment

Standard HVAC service equipment suitable for R22 systems:

• Vacuum pumps for system evacuation
• Refrigerant scales for accurate charging
• Charging hoses and accessories
• Service tools for R22 maintenance

Retrofit & Conversion Tools

Equipment for converting R22 systems to alternative refrigerants:

• Retrofit kits for R407C, R422D, or R438A conversion
• Flushing equipment for system cleaning
• Compatibility testing tools
• Conversion documentation and labelling

R22 System Applications

R22 is still found in many existing systems:

• Commercial air conditioning: Older office buildings and retail spaces
• Industrial refrigeration: Cold storage and process cooling
• Residential HVAC: Pre-2010 air conditioning and heat pump systems
• Chiller systems: Large commercial and industrial chillers
• Walk-in coolers: Commercial refrigeration in food service

Service Options for R22 Systems

Continue with Reclaimed R22

Service existing systems using reclaimed R22 refrigerant:

• Pros: No system modifications required, maintains original performance
• Cons: Reclaimed R22 is increasingly expensive and has limited availability
• Best for: Systems in good condition with several years of service life remaining

Retrofit to Alternative Refrigerant

Convert R22 systems to drop-in or near-drop-in alternatives:

• R407C: Most common R22 replacement (requires POE oil change)
• R422D / R438A: Drop-in alternatives (minimal modifications)
• Pros: Extends system life, more affordable refrigerant
• Cons: May require oil change, slight performance differences

System Replacement

Replace the R22 system with modern, efficient equipment:

• R410A systems: Higher efficiency, environmentally friendlier
• R32 systems: Lower GWP, excellent efficiency
• Natural refrigerants: R290 for suitable applications
• Long-term solution: Modern equipment with better performance

R22 Refrigerant Facts

• Chemical name: Chlorodifluoromethane (HCFC-22)
• ASHRAE number: R22
• GWP: 1,810 (100-year horizon)
• ODP: 0.055 (ozone depleting)
• Flammability: Non-flammable (A1 classification)
• Colour code: Green cylinder
• Phase-out reason: Ozone depletion (Montreal Protocol)

R22 vs Modern Refrigerants

Legal & Compliance

• Recovery mandatory: R22 must never be vented to atmosphere
• Reclaimed only: Virgin R22 production banned in EU/UK
• Proper disposal: Recovered R22 must be reclaimed or destroyed
• Documentation: Keep records of R22 recovery and disposal
• F-Gas regulations: R22 is subject to strict handling requirements

Important Notes

• Recovery is mandatory: Never vent R22 to the atmosphere (illegal and harmful)
• Limited availability: Reclaimed R22 supply decreasing, prices increasing
• Plan for replacement: Consider system replacement or retrofit options
• Proper training: Ensure technicians are F-Gas certified for R22 handling
