Question about our products


Below freeze prevention heating for cold stores

As soon as an a cold store is built into the ground, it is possible that, depending on the temperature within the cold store, walls and eventually the earth around it, start freezing. This causes the water contained within the earth to expand, which can lead to massive damage to walls and foundations. That is why the cold transmission into the ground has to be prevented by a below freeze prevention heating system.

Below freeze prevention heating by Hemstedt, simple and durable

The frost protection by Hemstedt is simple to use. Heating cables pre-assembled into heating mats are being laid and then cast into the foundation or walls. Temperature sensors make sure that temperatures of walls and floors are kept steady, thus creating a reliable freeze prevention around the cold store.

Below freeze prevention heating and energy efficiency

When operating an icehouse, energy consumption is important, and it is also important concerning the operation of a below freeze prevention heating. The systems of Hemstedt provide intelligent control systems that heat the under-soil heating only as long as it is necessary to prevent a malicious cold transfer into the ground. Thus, the below freeze prevention heating does not consume unnecessary energy

Below freeze prevention heating without external power

Additionally, there is the possibility to power the frost protection by, for example, a photovoltaic system. In combination with battery storage, the below freeze prevention heating can be powered at night without expensive external power. Not only does this have economic benefits, it also contributes to protecting the environment. 

Doubly safe below freeze prevention

Hemstedt offers safe heating cables with two independent circuits. That way, a reliable below freeze prevention heating is ensured at any time over decades, even if a heating circuit should take damage. Additionally, our frost protection mats are equipped with the HEM-SYSTEM, the sleeveless transition between cables. That does not only ensure a simple laying process, but also makes our cables 100% water-proof.

Electric below freeze prevention heating on the floor

Extensive below freeze prevention in your cold store, that covers all areas where the cold store walls and the ground are in contact, helps prevent heat extraction through the ground.

Electric below freeze prevention heating on the walls

In cold storages that are built into the ground - whether fully or partially - an electric below freeze prevention heating mat allows for the temperature of the walls to be raised just enough to match the ambient temperature.
