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.
