Freezer Frost Heave Prevention

In freezers, ice arenas, cold stores and other commercial areas, freezing temperatures can seep through the floor, even when well insulated. To avoid damage by frost heave, our self-regulating systems are efficient, simple and cost-effective. Much more so than hydronic heating systems.

What is frost heave exactly?

Freezing temperatures inside commercial freezers, ice arenas or other cold room areas can seep through the floor, even when well insulated. As the soil underneath freezes, capillary action draws water into the frozen areas, where the water forms a concentrated ice mass. As the ice mass grows, it can heave the floor and columns, causing structural damage and putting your valuable inventory at risk.

Preventing freezer floor heave damage efficiently

Effective frost heave protection is installed in the subfloor, under the freezer-floor insulation. To meet modern building standards, that system should be environmentally safe, energy-efficient, easy to design, install and maintain and cost-effective as well. That is where self-regulating technology comes in.

Self-regulating frost heave prevention systems are straightforward

Frost heave prevention systems by nVent Thermal Management Building Solutions have a simple design:

  • nVent RAYCHEM self-regulating electric trace-heating cables
    adjust their power output to compensate for temperature variations
  • easy-to-install connection kits and accessories
    for making electrical connections and properly completing the installation, such as power connections, end seal kits and junction boxes
  • advanced control systems
    controllers that monitor and/or control the trace-heating cable to help maintain surface temperature
Decades of experience in self-regulating technology

As the world leader in trace-heating solutions we are known for technical leadership and expertise in polymer science and radiation cross-linking. With more than 40 years experience in manufacturing self-regulating heating cables and over 400,000 km of cable installed worldwide, we offer proven technology and the highest quality.
