R290 Tools
R290 (Propane) Natural Refrigerant Tools
Professional HVAC tools and equipment designed for R290 (propane) natural refrigerant systems. R290 is an environmentally-friendly, low-GWP hydrocarbon refrigerant increasingly used in domestic refrigeration, small air conditioning systems, and commercial applications as part of the transition to natural refrigerants.
Why R290 is Growing in Popularity
R290 (propane) offers significant environmental benefits:
- Ultra-low GWP: Global Warming Potential of just 3 (vs R134a's 1,430)
- Zero ODP: No ozone depletion potential
- Excellent efficiency: Superior thermodynamic properties improve system performance
- Natural refrigerant: Readily available, low-cost hydrocarbon
- Future-proof: Not subject to F-Gas phase-down regulations
R290 Compatible Tools & Equipment
Manifolds & Gauges
Pressure gauges and manifold sets suitable for R290 systems. Standard HVAC manifolds work with R290, but must be dedicated to hydrocarbon use to prevent cross-contamination.
Leak Detectors
Electronic leak detectors specifically calibrated for hydrocarbon refrigerants:
- Sensitive to propane and other hydrocarbons
- Essential for safety when working with flammable refrigerants
- Detects leaks down to trace levels
- Prevents dangerous gas accumulation
Recovery & Charging Equipment
Dedicated recovery machines and charging equipment for R290 systems. Must be used exclusively for hydrocarbon refrigerants to prevent contamination and ensure safety.
Vacuum Pumps & Accessories
Standard vacuum pumps suitable for R290 system evacuation. Proper evacuation is critical for R290 systems to ensure optimal performance and safety.
Safety Equipment
Essential safety equipment for working with flammable refrigerants:
- Hydrocarbon-specific leak detectors
- Ventilation and gas detection systems
- Spark-proof tools where required
- Safety signage and labelling
R290 Applications
- Domestic refrigeration: Fridges, freezers, and wine coolers
- Small air conditioning: Room A/C units and portable systems
- Commercial refrigeration: Display cabinets, vending machines, ice makers
- Heat pumps: Domestic and light commercial heat pump systems
- Retrofit applications: Converting R134a systems to R290
Safety Considerations for R290
Flammability
R290 is classified as A3 (highly flammable) refrigerant:
- Charge limits: Typically limited to 150g in domestic applications
- Ventilation required: Adequate ventilation essential during service
- No ignition sources: Eliminate sparks, flames, and hot surfaces
- Leak detection mandatory: Always use hydrocarbon leak detector
- Training required: Technicians must be trained in flammable refrigerant handling
Best Practices
- Use dedicated tools for R290 (prevent cross-contamination)
- Ensure adequate workspace ventilation
- Check for leaks before and after service
- Follow charge limits strictly
- Use appropriate safety equipment
- Label all R290 systems clearly
R290 vs Traditional Refrigerants
| Property | R134a | R290 (Propane) |
|---|---|---|
| GWP | 1,430 | 3 |
| ODP | 0 | 0 |
| Flammability | Non-flammable (A1) | Highly flammable (A3) |
| Efficiency | Standard | Higher (5-10% improvement) |
| Charge size | Standard | Reduced (typically 40-50% less) |
| Cost | Moderate | Low |
Regulatory & Standards
- EN 378: European standard for refrigerating systems using flammable refrigerants
- IEC 60335-2-40: Safety requirements for household refrigerators
- Charge limits: 150g for domestic applications (varies by jurisdiction)
- F-Gas exempt: Not subject to F-Gas regulations (natural refrigerant)
