DOMETIC CFX3 Single Zone Wi-Fi Fridge Freezer (35, 45, 100)

SKU: DM-9600024617

Dometic's updated CFX3 line of portable fridge/freezers is perfect for overland adventures, and is equipped with one of the highest performing and quietest compressors on the market. CFX3 fridge freezers are capable of achieving sub-zero temperatures with an ultra-low power draw from your 12V battery, achieving an A++ energy efficiency class rating. Compared to a standard ice-requiring cooler, a fridge/freezer gives you 60% more usable space for the same exterior dimensions and 100% freedom from soggy, water logged food.

What's new with the CFX3 model? The CFX3 internal compartment has been redesigned to eliminate the dairy compartment, which means more internal storage space in the same external footprint. Now all inner walls of the CFX3 unit are cooled with an extended evaporator so you can store an even more impressive amount of fresh food and drinks. Dometic also souped up the USB charging port so you can feed those power-hungry small electronic devices. The CFX3 USB port is 4x more powerful and is now conveniently located right next to the new, sleek high-resolution color display.

Like the CFX before it, the CFX3 is rugged, lightweight, and ready to go where you go. The CFX3 can operate using AC, DC, or solar powered battery systems. Dometic CFX3 fridge freezers provide a reliable, energy-efficient food storage solution that enables you to enjoy gourmet meals during off-grid camping trips for weeks on end without needing to resupply your provisions. .

NOTE: This is a single zone (uniform temperature) fridge/freezer. For a dual zone unit where you can have 2 separate temperature zones, please see the Dometic CFX3 Dual Zone Wi-Fi Fridge Freezers. For an ice-making capable, single zone unit, see the 55 quart CFX3 55IM.

NOTE: The 35 and 45 models are hinged on the shorter dimension and open "the long way". The 55IM, 75DZ, 95DZ and 100 models are hinged on the longer dimension and open "the short way". Please note the hinge location in the product photos.

NOTE: The demand for CFX3 Fridge Freezers is extremely high right now. We will fill all orders on a first-come, first-serve basis. However there may be a lead time of several weeks before your unit is available. Please plan ahead and order well in advance of planned adventures.

Dometic CFX3 Fridge Freezer Features

CFX3 Fridge Freezer Electronic Component Features

  • CFX3 next-gen electronics include an intelligent automatic "turbo mode". The variable speed VMSO3 compressor will ensure the temperature you set is reached quickly and maintained accurately.
  • Ultra Efficient Compressor = Ultra Quiet Fridge Freezer - incredibly efficient compressor is capable of achieving deep-freeze (-7.6 F) temperatures without whining about it
  • High resolution color display on front panel allows for monitoring & precise temperature control via push buttons (Wi-Fi app can also be used).
  • 3 Stage Dynamic Battery Protection System automatically shuts the product off to prevent a dead car starter battery and improves car battery performance. Choose from Low/Med/High settings for voltage cut-off point.
  • Power using Solar Panels, DC, or AC - minimal draw when using AC or DC power source. With such an efficient compressor you can easily supplement your 12V system with an appropriate solar panel to run your fridge indefinitely. Note- the solar panel doesn't plug into the CFX3 directly; rather the panel would go to a charge controller and 12V battery, which would wire into the fridge.
  • USB port (5V/2A) - CFX3 now boasts a more powerful USB charging port for your electronics, located in a more accessible location- front and center, right next to the display.
  • Internal LED light turns on upon opening the lid for efficient late night meal prep while camping. This light will flash to attract your attention if the fridge has been left open for more than 3 minutes. 
  • Wi-Fi enabled - run diagnostics, monitor & adjust temperature, check battery voltage remotely from Dometic's CFX3 App on your phone (Available at Apple Store and Google Play- see below for more details). 

Dometic CFX3 Fridge Freezer Design Features

  • Rugged Construction - Thermoplastic polymer construction, reinforced ExoFrame corners, and robust fully insulated lid with stainless steel hinges.
  • Removable & flippable lid- can have hinge on either side, customizable for your specific set up
  • Spring-loaded aluminum alloy handles can be used as tie down points, as handles, and are able to fold down or even be removed completely if clearance is an issue.
  • Mount fridge directly to slider (sold separately) using screws - no need for cumbersome tie downs. Base of fridge has threaded inserts for M6 hardware.
  • Easy to clean - Drain plug and flush mounted evaporator unit make it a breeze to clean even after heavy use
  • Tight sealing lid and extra thick polyurethane insulation keep the coolness in even when the power is off.
  • High efficiency compressor can cool contents to -7.6F (-22C) for a deep freeze. As reference, the average kitchen refrigerator at home is set to 35F to 40F, and most kitchen freezers are set to -4F to 0F.
  • Removable wire baskets with dividers for improved organization
