Excellent support from Kiravans

A couple of weeks ago I bought the CB40 fridge, I powered it up at home and was pleased to find it didn't take more than 4.5A even when first powering up so I would see that as a maximum power consumption below the rated value. Unfortunately when I took it to my boat it wouldn't fit due the to curved hull and my poor measuring. I called Kiravans and they immediately agreed to take it back and provide a refund, even organising the courier for the return. Through the order and return the staff at Kiravans were helpful and knowledgeable. I will definitely be ordering from them again.


We installed this last week and used for the first time this weekend (very very hot!). It worked really well, especially considering the weather. We've very pleased with it.

Pros: Very easy to plug in and play. Very cold, stayed cold even when unplugged for hours. Capacity is massive.

Cons: Instructions not very clear on exactly how it should be fixed into position. Extremely expensive.

Obviously the surface needs to be cleared each time you use it, but we all know that before buying so not really an issue.


Not sure about a front opening fridge? Maybe the Dometic CB40 top loading fridge will suit your campervan set up better. 

The Dometic CoolMatic CB 40W is the go to fridge for tight spaces. With low energy consumption and a detachable cooling unit, there are plenty of features to be enjoyed on this 40 l fridge. A handy 1.5 m lead gives flexibility of position and its temperature range of +10 °C to –12 °C allows varied use.

To turn the fridge on, simply twist the thermostat knob to the right. The unit will take about 60 seconds to start the compressor.

Notes on fitting

  • Must be fitted in a location where heated air from the unit can dissipate easily. Failing to do this will result in excess battery use.
  • Powered by a 12volt leisure battery but to avoid a drop in performance the cable should be kept as short as possible, a graph showing the appropriate cable diameter for the length of cable run is included in the installation guide.
  • The lid rests on top of the unit and is not attached - normally the worktop is fixed to the lid and hinged from the back of the cabinet.

    Still can't decide?

    Not sure if a top loading fridge is for you? Have a quick read through our pros and cons to help you decide... 


    1. It will fit in the side cabinet of a T5 alongside your bench seat - a part of the campervan furniture which is often difficult to make use of. Typically this area does not have front access and is, therefore, a bit under utilised. By fitting the fridge here you free up a decent bit of space for a front opening cupboard.
    2. It seems to hold more than front opening fridges. Sure, front opening fridges have bottle holders, shelves and freezer sections - but these often seem on the smaller side. I often find myself squashing stuff into every little corner of front-loading fridges, whereas with this top loader it all just fits nice and easy. Ok so you won't have a milk bottle holder or a special space for eggs in the door of the fridge - but you can carry giant orange juice cartons, lots of wine bottles etc!


    1. One of the most obvious downsides is having to clear the worktop every time you want something out of the fridge.
    2. Another potential downside to many is the lack of a freezer compartment. Unlike the CRX50, you can't keep your frozen goods separate with this fridge. However, there is a way around this. You will be able to see which side of the fridge houses the chiller plates when you unpack your fridge. By simply dropping the temperature a little on the thermostat knob and placing your ice-cream over the top of the chiller plates you will find that things stay very well frozen.
