What is R290?

Propane (R290) is a natural hydrocarbon refrigerant that offers exceptional environmental performance and energy efficiency.

Ultra-Low GWP

R290 has a Global Warming Potential of just 3, compared to 1430 for R134a and 3922 for R404a.

Zero ODP

R290 has zero Ozone Depletion Potential, making it safe for the ozone layer unlike older refrigerants.

Energy Efficient

R290 systems are 5-10% more energy efficient than traditional HFC systems, reducing operating costs.

Future Ready

R290 is exempt from the HFC phase-down, ensuring long-term compliance with environmental regulations.

Safety Standards

R290 is classified as A3 (low toxicity, high flammability) but is safe when used within established guidelines.

Flammability Class

R290 is A3 classified (highly flammable). Requires proper installation by certified technicians following NZ standards.

Charge Limits

Small units: ≤150g
Commercial: ≤500g
Max practical: 1.5kg with safety measures

Ventilation

Minimum 4 air changes per hour required. Systems must be installed in well-ventilated areas per AS/NZS standards.

Leak Detection

Electronic leak detectors required. Visual inspections mandatory. Annual certification required for commercial units.

NZ Standards

Compliant with AS/NZS 5149 refrigeration standards and WorkSafe NZ guidelines for flammable refrigerants.

Certified Installers

Only licensed refrigeration technicians may install, service, or repair R290 systems in New Zealand.

HFC Phase-Down Timeline

New Zealand is implementing the Kigali Amendment to phase down HFC refrigerants. R290 is exempt.

2024
-35%
Current Phase
35% reduction in HFC imports compared to baseline. Higher GWP refrigerants becoming restricted.
2027

Frequently Asked Questions

Everything you need to know about R290 propane refrigerant.

Yes, R290 is safe when used within established guidelines. While it is flammable (A3 classification), the small charge amounts used in modern systems (typically 150-500g) are well below dangerous thresholds. Proper installation by certified technicians, adequate ventilation, and leak detection systems ensure safe operation. R290 has been used safely in Europe for over a decade.
Retrofitting is generally not recommended. R290 requires different compressor oils, materials compatibility considerations, and safety systems designed for flammable refrigerants. It's usually more cost-effective and safer to replace aging R134a systems with purpose-built R290 equipment. This also ensures full warranty coverage and compliance with NZ safety standards.
R290 systems must be serviced by licensed refrigeration technicians trained in flammable refrigerant handling. Annual leak testing is mandatory for commercial units. Service requires spark-free tools, proper ventilation, and leak detection equipment. Service records must be maintained for compliance. Despite these requirements, R290 systems typically have lower maintenance costs due to fewer mechanical issues.
No. R290 is a natural hydrocarbon refrigerant, not an HFC, and is completely exempt from the HFC phase-down regulations under the Kigali Amendment. This makes it a future-proof choice as synthetic refrigerants like R134a, R404a, and R410a become increasingly scarce and expensive through 2035.
R290 systems are typically 5-10% more energy efficient than equivalent HFC systems. This is due to propane's favorable thermodynamic properties, including lower compressor discharge temperatures and better heat transfer characteristics. Over a 10-year period, this efficiency advantage can result in significant electricity cost savings, especially for 24/7 commercial refrigeration.
NZ follows AS/NZS 5149 standards with these charge limits: Small units (domestic/commercial under-counter): ≤150g. Commercial display cases: up to 500g. Larger commercial systems: up to 1.5kg with enhanced safety measures including ventilation and leak detection. Festivé R290 models are designed well within these safe limits.
