Why Refrigeration Matters on the Water

Whether you're heading offshore for a full day, staying overnight in a cabin cruiser, or running a sportfishing rig, keeping provisions, drinks and bait at the right temp matters. A sub-par cooler means more time managing ice and less time enjoying the trip. The Dometic CFX5 Series solves that by offering true compressor-drive cooling, not just blocks of ice.

What Sets the CFX5 Series Apart

• Built with vacuum-insulated panels (VIP) for superior thermal efficiency. 
• Equipped with the VMSO 3.5 compressor for deep-freeze capability down to –7°F (–22°C) in tough conditions.
• Bluetooth/WiFi smartphone control via the Dometic app—monitor temps and power draw from anywhere on your boat. 
• Rugged marine-ready build: ExoFrame design, reinforced corners, built-in bottle opener and premium features.

Real Boat Setup Tips

• Match the unit size to your available space and power budget (12V/24V or AC shore power).
• Secure the cooler to your deck or console using proper mounting hardware to account for motion.
• Pre-cool ahead of your trip so heavier loads don’t drive the compressor hard when underway.
• Use the Dometic app to monitor power draw and avoid draining your boat’s battery.
• Use accessories like protective covers, slide mounts and tie-downs to ensure your cooler lasts seasons of use.
