This unit can be used as either a Freezer or Fridge, and can maintain -18oC even in 43oC ambient.
The 60mm thick wall insulation and complete coverage wall and floor cooling plates ensure the lowest possible battery consumption, making this one of the models ideally suited as a permanent portable freezer or extreme duty fridge.
12/ 24v DC and 240v AC are all built in and the unit will automatically select to run on mains power whenever it is available - but revert to battery power if the mains go off.
A digital thermostat that can be set down to as low as minus 30oC ensures the unit maintains your desired temperature range without the need to adjust for hotter or colder weather.
Ripple stainless steel outer cabinet and smooth stainless steel internal lining for maximum durability and ease of cleaning.Four (4) baskets fitted as standard.

Why Buy a National Luna?

Originally designed to meet World Health Organisation specifications for transporting medicines in harsh African conditions, National Luna fridges are now the preferred choice of safari operators, caterers, mining companies, travellers and 4WD'ers who desire commercial grade quality and serious performance with low battery consumption in demanding conditions.
What makes National Luna better?.... Performance is the answer! Performance in the form of a proven ability to refrigerate or freeze safely in very hot weather and to deliver this performance with the lowest possible power consumption, with reliability and a long life second to none. Food lasts longer and no matter what the climate, you will have a working fridge or freezer.

How is the Performance Achieved?

Three key design features help deliver the best refrigeration performance.... 1. Cooling platesthat also form the inner walls deliver cooling to all inner walls from top to bottom, ensuring consistent temperatures all around the cabinet and fast "pull-down" times. 2. Insulation density- all National Luna fridge/freezers use parallel internal walls and outer cabinets.... this is to allow a unique insulation injection process where the inner and outer walls are supported in a special jig (a bit like a wool-bale press), so that the foam can be injected at higher pressure thus a higher density. So, just like "pink batt insulation" where an R3.0 batt outperforms an R2.5 batt for a similar thickness, it is the density of insulation that gives the improved performance without wasting space. Wall thickneses range from 42mm to 60mm and we recommend for users wanting a full time Freezer, that you choose from our thick-wall range (40,55,65,72,80,110 & 125 Lt) or of course our 60 and 90 Twins which use thick-walls on the freezer side. 3. Door sealsmade the same as commercial fridges, with an air pocket that inflates and seals using the difference in air pressure between the cool inside and warm outside. No thin rubber strip seals in a National Luna! These key features combine with all the other National Luna design features and quality components to ensure the compressor can run for the shortest possible time which means low battery consumption and performance reserves for tough demands.

Other Important features....

Choice of Models- Where freezer use is planned the 40Lt to 125Lt in our "thick wall" single bin range are ideal. Portable freezers that can actually freeze freshly caught fish in a safe time, and not just keep something frozen. And by adjusting your thermostat these models can also be super efficient Fridges. Weekender models in 52Lt Single Bin (Fridge or Freezer) or 50Lt Twin Bin (40Lt Fridge & 10Lt Freezer) are the perfect size and layout for recreational users. The 60Lt and 90Lt Twins offers "two in one" - a thick wall Freezer (25Lt for the 60 and 40Lt for the 90), and a thin wall Fridge (35Lt for the 60 and 50Lt for the 90) but with individual controls so it can also be two freezers or two fridges and with just a single compressor to run it saves on space and battery power. 72Lt and 110Lt double door models also offer "thick wall" efficiency and individual control of each compartment for professional tour operators and catering companies, or anyone who wants premium performance and the separation of two lids.   Metal construction - All National Luna fridge/freezers are built with stainless steel or aluminum internal and external walls. The durability benefits over plastic fridges are obvious.... but metal walls with integral cooling plates also give National Luna superior cooling, extra internal space, and high efficiency. A stainless steel chassis forms the "backbone" of every National Luna and includes keyhole slots for use in conjunction with an optional fixed Base Plate fitted with Mushroom head bolts (secure mounting without ropes or straps) Danfoss Compressors - German engineered and recognized as the most efficient portable fridge compressor in the world, National Luna use only genuine European made Danfoss Compressors and Controllers as the heart of the performance, but then design their own fan-assisted condenser, full wall plate evaporator system, control panel and interface for maximum efficiency and reliability. Clever Controls- 12/24v DC can be connected at the same time as built-in 240v AC and National Luna will automatically use the 240v AC whenever it is available. It will revert to DC automatically if the mains power goes off - great for overnight stays in remote stations where the generators are turned off late at night. The controls also detect battery voltage and when the engine is charging the compressor will be run at high speed for maximum performance but automatically revert to battery save mode when the engine or charger is off. Turbo Mode can be used to over-ride this function. Digital Thermostats - simply set the temperature average you need and the National Luna controls will cycle the fridge around this temperature no matter whether it is a hot day or cold night. No need to constantly adjust the fridge to avoid freezing the vegies or even worse - risk warming the beer! After setting your desired temperature, the display reverts to showing you the internal cabinet temperature so you can see at a glance what is going on inside. Low Battery Cut-Out - adjustable and included on all models. On Weekender 50 & 52 Lt models the battery cut-out can be seen using the built-in battery monitor indicator. When the battery cut-out is triggered, the compressor is stopped but the digital temperature display continues to show you internal temperatures so you are kept informed. Handles and Catches - stainless steel and heavy duty spring loaded fold-flat handles double as tie-down points. The lockable stainless steel catches ensure that even on the roughest roads the lid remains secure. Solar Panel Friendly - by ensuring the lowest possible battery consumption through clever design and quality components National Luna is ideally suited to solar applications and can typically use less solar array than most other portable fridges. Typically a 65-80watt panel is all that is needed to maintain a battery powering a National Luna fridge *** Obviously this is dependant on sun-hours and all the other variables, but our own experience and customer feedback supports the claim that National Luna uses less solar panel array - especially when comparing our larger size models with the competitor's products. 3 Year Warranty- Even with the best design, quality and components, unfortunately sometimes things go wrong.
