How does it work?

The Groundfridge is dug in and covered with the excavated soil from its new location. This covering layer of soil is about 1 meter thick and has sufficient insulating properties for the core temperature within the Groundfridge to barely vary. Furthermore, your Groundfridge is fitted with a ventilator. This battery-driven ventilator offers you the option of setting ventilation times to your desired specifications. Night venting will have a positive effect on reducing interior temperature, as letting the cold night air can see it drop rather rapidly. We recommend venting your Groundfridge at least one full hour every twenty-four hours.


The temperature level inside your Groundfridge will more or less match the temperature on its outside at a depth of one metre below ground. Its interior temperature is affected by local factors such as soil type, ground water levels, exposure to sunlight, mound vegetation and the average outside temperature.

How does it work with The Chiller?

During peak temperatures the additional active cooler circulates and cools down the air inside the Groundfridge. The extra cooling power keeps the Groundfridge at a guaranteed and constant temperature which is adjustable to fit desired (professional) use.
