Detailed FAQ Section
How much power does the Engel MT35 fridge-freezer consume?
The Engel MT35 is incredibly efficient. Depending on the ambient temperature and internal load, it consumes between 0.7 to 2.5 amps per hour on DC power. This means it can operate off a 100Ah battery for several days without needing recharge, especially when combined with a solar panel system. The efficient Swing Motor Compressor plays a critical role in minimizing energy draw, which makes the MT35 ideal for long voyages or boats running entirely on solar.
Can the Engel MT35 fridge-freezer operate as both fridge and freezer?
Yes, the Engel MT35 can function as either a refrigerator or a freezer. However, it cannot do both simultaneously due to its single-zone cooling system. You can set the digital thermostat to the desired temperature range using the control panel. For refrigeration, set it around 1-4°C (34-39°F); for freezing, adjust it to as low as -18°C (0°F). This versatility allows you to switch usage based on your storage needs.
What are the dimensions and fitment needs of the Engel MT35 fridge-freezer?
The MT35 measures approximately 25.5”L x 14.3”W x 16.9”H. It fits snugly in many boat galley lockers or RV under-bench compartments. When planning installation, consider additional clearance for ventilation — at least 2” on all sides. The unit includes built-in carry handles and mounting brackets, giving you flexible installation options onboard or dockside. Many users choose to place it inside a custom wooden or fiberglass frame for a seamless look.
How does the Engel MT35 fridge-freezer compare with other marine fridges?
Compared to other marine coolers in the same class, the Engel MT35 outshines most in terms of energy efficiency, build quality, and low noise levels. The Swing Motor Compressor makes less noise than conventional rotary compressors and consumes fewer amps. While some models offer more capacity, the MT35’s durability and power performance make it a better long-term investment. For serious mariners, it strikes the perfect balance of size, function, and reliability.
Is the Engel MT35 fridge-freezer worth the cost?
Yes — while the Engel MT35 is priced higher than basic models, it offers unmatched performance, longer life, and better power efficiency. This reduces long-term operational costs and ensures fewer breakdowns. Additionally, Engel units retain strong resale value due to their global reputation and warranty support. For those relying on a fridge-freezer during critical journeys, this investment quickly pays for itself in food preservation, battery savings, and peace of mind.
Conclusion
The Engel MT35 fridge-freezer continues to be a gold-standard portable refrigeration option for boaters, RVers, and expedition travelers.
