Low-GWP refrigerant gases for marine and offshore systems

DEFRA has proposed tightening the UK F-gas phasedown from 2027 onwards, which will make high-GWP refrigerants harder to source and more expensive over time. For vessel operators, it makes sense to transition early.

Star International supplies a range of low-GWP refrigerant gases suitable for marine HVAC and refrigeration systems, backed by technical support and onboard servicing to keep downtime to a minimum.

Why act now?

• Stay ahead of DEFRA’s proposed phasedown: reduce reliance on high-GWP HFCs before quotas tighten.
• Protect budgets: avoid future price spikes and supply constraints on older gases.
• Support sustainability goals: lower overall greenhouse gas impact from onboard cooling.
• Marine-ready advice: we match refrigerants to your existing systems and approvals.

How Star International helps

• Supply of low-GWP refrigerant gases in marine-friendly pack sizes
• Guidance on suitable replacements for legacy high-GWP refrigerants
• Onboard support/servicing to complete changeovers safely
• Flexible, responsive service to fit vessel schedules

Contact our team with vessel type, current refrigerant and system details, and we’ll recommend the most appropriate low-GWP option.

Note: DEFRA’s changes are currently at consultation stage; operators who prepare early will be in the strongest position once the new schedule is confirmed.
