Marine HVAC, where downtime costs sailings.
Passenger vessels need air conditioning that is reliable in a salt-laden environment and repairable on a tight schedule. We diagnose faults, plan recovery and keep vessels in service.

What matters
Fix it properly, between sailings.
On a vessel, the repair plan matters as much as the repair.
- Fault-finding on condensers, compressors and refrigerant circuits
- Staged recovery plans that limit time out of service
- Corrosion and salt exposure considered in every repair
- Refrigerant handling and records by licensed technicians
- Recommissioning and records for the operator
- Maintenance planning to avoid repeat failures

Do you work on vessels in service?
Yes. Recovery and repair work is planned around the operator’s schedule so vessels spend as little time out of service as possible.
Can you maintain vessel HVAC on an ongoing basis?
Yes. A maintenance plan can be set up around the vessel’s operating schedule and the faults history.
