Optimizing HVAC for Crew Comfort and Energy Efficiency

Comfortable living spaces and controlled atmospheres are vital for crew performance—and fuel efficiency. Here’s how Carat Maritime designs, installs, and maintains HVAC systems tailored to your vessel’s unique profile.

Marine HVAC differs from land systems: salt, vibration, and space constraints demand robust components. We specify marine-grade compressors, corrosion-resistant coils, and vibration-isolated mounts to withstand harsh conditions.

Air handling units are sized using psychrometric calculations, balancing supply-air temperature with humidity control. Carat Maritime’s designers factor in crew quarters layout, galley loads, and pump-room ventilation needs.

Energy-Saving Strategies

Heat recovery modules capture waste heat from engine room exhaust or jacket cooling water to pre-heat supply air, cutting overall HVAC load by up to 20%.

Regular filter replacements and duct-cleaning keep airflow optimal—preventing pressure drops that force compressors to work harder.

Our Planned Maintenance Service includes refrigerant leak checks, sensor calibrations, and belt-tension inspections, ensuring continuous comfort and efficiency.
