Frost Heave Prevention

Ice build-up can be dangerous

Ice build up underneath tanks can cause problems and damage such as unwanted or uncontrolled movement or elevation of the tank. Subfreezing temperatures  inside cold rooms and freezers can seep through the floor, even when it is well insulated. As the soil underneath freezes, capillary action draws water into the frozen areas where it forms a concentrated ice mass. As the ice mass grows, it can heave the floor and columns, causing structural damage and putting valuable inventory at risk in areas such as:

  • LNG terminals
  • Cryogenic storage tanks
  • Freezers, ice arenas and cold rooms in commercial environments

Frost heave prevention of Tanks 

Our system prevents frost heave by applying thermal insultaion around cryogenic tanks and by applying electric heat tarce cables to the concrete layers underneath the tank. We can engineer and design a complete Turnkey system that included heat trace cables, power distribution system and control and monitoring system to help oversee your environment.

Freezer Frost heave prevention 

we offer a freezer frost heave prevention system that when installed in the subfloor under the freezer-floor insulation, can prevent frost heave damage in commercial freezers, ice arenas or other cold room areas.

Our systems have a simple design consisting of:

  • Electric heat trace cables – nVent RAYCHEM RaySol heat trace cables adjust their power output to compensate for temperature variations and can be installed in conduit; or nVent PYROTENAX MI heat trace cables which are supplied as complete factory-fabricated assemblies, provide constant power output, and can be installed in conduit or directly embedded underneath the subfloor
  • Connection kits and accessories – easy-to-install items for making electrical connections and properly completing the installation, such as power connections, end seal kits and junction boxes
  • Advance control systems – controllers that monitor and/or control the heat trace cable to help maintain the temperature of the surface

No environmental concerns

Hydronic heating systems rely on circulating warm fluids, like a glycol-water mix, to prevent frost heave. Not only is it inefficient, this can create environmental hazards due to the risk of leaking glycol. nVent RAYCHEM frost heave-prevention systems use electric heat trace cables for effective heating and reduced environmental risks.

Custom analysis and designed solutions

Designing a reliable frost heave system requires expertise. Our engineers design a complete system based on a comprehensive thermal analysis using:

  • State-of-the-art SlabHeat™ software tool
  • 2D- and 3D- finite element analysis (FEA)

Our solutions are designed to minimize both installation and operating costs, while maximizing energy efficiency, safety and long-life functionality.
