Dometic CK40D Thermoelectric / Compressor Hybrid Cooler is a multi-purpose fridge and freezer, this hybrid compressor cooler is highly efficient and provides excellent performance.. Two cooling systems in one box.

Are you looking for a highly efficient cooling appliance for the awning, the patio, or the garage workshop? Ideally, also for the car or recreational vehicle? Then the Dometic CoolFun CK 40D HYBRID
is just what you need: two cooling technologies, two connection options and a generous capacity of 38 litres.

Powerful compressor cooling on the 230-volt mains, thermoelectric cooling on a 12-volt vehicle battery – this hybrid cooling box can do both. It makes a reliable freezer for perishable deep-frozen food, chills the drinks for your garden party, and it will also keep your provisions nicely fresh on the journey to your holiday destination. On top of all this, it looks stylish with its shapely black/silver

This is the world's first dual cooling system. The new Dometic CK40 Hybrid (formally Dometic B40) incorporates a powerful compressor for static use, as well as a thermoelectric cooling unit for use on the move with deep-freezing up to -15°C.

An amazing low cost solution for all your needs!

A compressor cooler for stationary and mobile use can be hard on your pocket. The new B40 won’t. Designed as a typical awning cooler it incorporates a powerful compressor as well as a thermoelectric cooling unit. The latter comes in when the cooler is connected the 12-volt car battery. This ensures that the cool chain is maintained during transport from home to the campsite. An amazing and low cost technical solution for an important comfort feature. In compressor mode the B40 provides cooling and deep-freezing up to –15°C, even at high ambient temperatures. The thermoelectric system achieves 20°C below the ambient temperature. About 40 litres capacity, sturdy cabinet, recessed grips on the sides.

Features at a Glance
  • Compressor: Continuously Refridgeration and Deep Freezing, +10°C to –15°C
  • Thermoelectrics: Cooling max. 20 degrees below ambient temperature
  • Recessed side grips for convenient transport
  • 230 volts AC normal/deep-freezing (compressor)
  • 12 volts DC normal cooling (thermoelectrics)
  • Electronic thermostat with digital display (in compressor mode)
  • Lid with all-round seal and magnetic lock
  • Especially quick cooling with extra strong insulation
  • Power consumption - DC 48watt, AC 65watt


What is the difference between the cooling technologies?
Details of distinguishing features:
  • Gas-powered cooling independent of electricity
  • Three way cooling – Gas, 12 volts DC or 230 volts AC
  • Silent operation
  • Cooling performance depending on the ambient temperature

The Technical Bit
A concentrated ammonia solution is heated in a boiler and expelled as vapour. The pressurised ammonia gas is then liquefied in a condenser. Supplied with hydrogen, it evaporates and in the process extracts heat from the storage container. The ammonia gas then enters the absorber where it is reabsorbed in a weak solution of ammonia. Finally, the saturated solution flows back to the boiler where the whole cycle starts again.

Details of distinguishing features:
  • 12 / 24 / 230 Volt
  • Independent of inclination
  • Lightweight and low-cost
  • Cooling performance depending on the ambient temperature

The Technical Bit
The thermoelectric principle was discovered by J. C. A. Peltier, which is why the temperature generating parts of thermoelectric systems are referred to as Peltier elements. Thermoelectrics are based on the fact that cold or heat energy (depending on the polarity) is generated when a DC current is conducted between different types of metal. The heating or cooling capacity is further enhanced by heat exchangers and air fans. Ideal for low and medium cooling volumes.

Details of distinguishing features:
  • Excellent cooling performance even at extreme ambient temperatures
  • Refrigeration and deep-freezing
  • 12 / 24 / 100 – 240 volts
  • Low power consumption – suitable for solar operation
  • Battery protection
  • Quiet operation with little vibration
  • Independent of inclination

The Technical Bit
Compressor units operate using a refrigerant that changes from liquid to gaseous state in the evaporator. The evaporation extracts heat from the interior of the cooling unit – the temperature drops. The compressor draws in the refrigerant, compresses it and passes it on to the condenser. Here, the absorbed heat is released to the atmosphere. The refrigerant liquefies again and flows to the evaporator, where the cycle begins again.

Forget The Rest, BUY THIS!

Ordered and delivered next day, awesome service. Out of the box, left for 30 minutes to settle, then on for 20 mins at lowest temp and there was ice inside. Put food/drinks in it ready for glamping weekend and let it chill for the night (just to make sure) at 2 degrees (with hindsight, it was way to cold) and the next morning it was at 2 degrees Celsius. 4 hours travelling in the van with it using 12v cigarette connection and the stuff was still cold. on-site camping power it still registered at 2 degrees C (was well surprised) beer was really really cold but it nearly froze the rest of the food (butter/lettuce). It runs really quiet, freezes really well, the handles could have a better grip as its not a light piece of equipment to carry, especially when loaded with foodstuffs. but it is amazing. running on 12v the display doesn't show the temp. but left it in the van during the day and overnight running on 12v (using leisure battery) and then moved it into the house the next day and it was still at 5 degrees. TLDR; was dubious, ordered then delivered nextday. froze beer, ruined butter and lettuce (too cold). to lazy to get it out of van, everything still cold next day.

We were concerned spending so much on a cooler but we couldn't be happier with the purchase. It has worked really well on a number of continent trips (high temps) and would recommend it. It is also really well put together.

Great service from Leisureshopdirect, received it the day after ordering it!

A Serious Piece Of Kit

We used the Dometic B40 during a drive to the south of France and as a mains powered fridge when we arrived. It provides superb performance in AC compressor mode. In DC thermoelectric mode it keeps food cool even in very hot conditions although it seems to draw a lot of current (not measured precisely) in doing so. The standard of insulation is high, with the (acceptable) downside that it makes the cooler fairly large. It is also pretty heavy. Overall, a professional quality product.
