Based on the self-regulating technology, the heating cables cover the entire range of heating applications in Cold/Freezer room. The self-Regulating design renders the heater burnout proof particularly at 'cross-overs' as the output will va over its entire length depending on temperature.

We offer Heating solution for

Frost Heave protection (Underfloor heating)

Fan cowling heating cable

Dip tray heating cable / heated dip tray

Freezer door heating cable

Viewing glass heating cable

Compressor body heating cable

The frost heave occurs when the ground under the cold storage freezes and expands causing faults in cold storage floor such as cracks or slope.

When a cold store is installed at ground level, its low temperature will gradually transfer through the floor into the ground beneath. If this is allowed to happen then moisture, which is naturally present in the earth, will start to freeze. As this moisture turns into ice and expands, it pushes up on the floor above, causing the cold store floor to crack and bow. This oſten results in an uneven and unsafe floor and disruption to the racking.

The floor and subfloor design includes multiple layers of concrete and insulation. Without a floor heating system, the soil temperature would fall below freezing and an ice lens would form that would cause buckling of the cold storage floor. The heating systems are designed just to apply enough energy to prevent frost from forming in the ground. The insulation makes sure that the heat is directed into the ground without impacting the temperature of the cold store above.
